Python usually uses an interpreter. The compiler are a little bit different.

Interpret translates line by line.

Compiler takes all lines to machine code.

What is programming language? We give some instruction to translator. They tell the machine what to do. Translator can be interpreter or compiler.

Return in python:

How it works:

without return it prints none:

def sum(num1,num2):
    num1+num2

print(sum(10,5))

def sum(num1,num2):

num1+num2

print(sum(10,5))

with return it prints something that I insisted for:

def sum(num1,num2):
    return num1+num2

print(sum(10,5))

def sum(num1,num2):

return num1+num2

print(sum(10,5))

Nested Return:

def sum(num1,num2):
    def another_func(num1,num2):
        return num1+num2
    return another_func(num1,num2)

#should do one thing really well.
#should return something
total=sum(10,20)
print(total)

def sum(num1,num2):

def another_func(num1,num2):

return num1+num2

return another_func(num1,num2)

#should do one thing really well.

#should return something

total=sum(10,20)

print(total)

#issues with print and return

def sum(num1,num2):
    def another_func(num1,num2):
        return num1+num2
    return another_func(num1,num2)
    return 5    #this line will not return because we have already returned something before
    print('hello') #this line will not print because we have already returned something before

#should do one thing really well.
#should return something
total=sum(10,20)
print(total)

def sum(num1,num2):

def another_func(num1,num2):

reduce() function and how it works in python:

I have seen two videos here from udemy and youtube to clear this concept for me

code from udemy:

reduce()

from functools import reduce
my_list = [1,2,3]
def accumulator(acc,item):
    print(acc, item) # to show how it is going
    return acc+item
print(reduce(accumulator,my_list,0)) #we are starting from 0 to iterate
print(reduce(accumulator,my_list,10)) #we are starting from 10 to iterate

from functools import reduce

my_list = [1,2,3]

def accumulator(acc,item):

print(acc, item) # to show how it is going

return acc+item

print(reduce(accumulator,my_list,0)) #we are starting from 0 to iterate

print(reduce(accumulator,my_list,10)) #we are starting from 10 to iterate

Output:

0 1

1 2

3 3

10 1

11 2

13 3

Exercise solutions here in function:

#1 Capitalize all of the pet names and print the list

my_pets = ['sisi', 'bibi', 'titi', 'carla']

def capiFunc(string):
    return string.upper()
print(list(map(capiFunc,my_pets)))

my_pets = ['sisi', 'bibi', 'titi', 'carla']

def capiFunc(string):

return string.upper()

print(list(map(capiFunc,my_pets)))

output:

['SISI', 'BIBI', 'TITI', 'CARLA']

1	['SISI', 'BIBI', 'TITI', 'CARLA']

#2 Zip the 2 lists into a list of tuples, but sort the numbers from lowest to highest.

my_strings = ['a', 'b', 'c', 'd', 'e']
my_numbers = [5,4,3,2,1]
list_number_new=sorted(my_numbers)
print(list(zip(my_strings,list_number_new)))

my_strings = ['a', 'b', 'c', 'd', 'e']

my_numbers = [5,4,3,2,1]

list_number_new=sorted(my_numbers)

print(list(zip(my_strings,list_number_new)))

#3 Filter the scores that pass over 50%

scores = [73, 20, 65, 19, 76, 100, 88]
def morethan50(item):
    return item>50
print(list(filter(morethan50,scores)))

scores = [73, 20, 65, 19, 76, 100, 88]

def morethan50(item):

return item>50

print(list(filter(morethan50,scores)))

#4 Combine all of the numbers that are in a list on this file using reduce (my_numbers and scores). What is the total?

def addition(accu,item):
    return accu+item
print(reduce(addition,(my_numbers+scores),0))

def addition(accu,item):

return accu+item

print(reduce(addition,(my_numbers+scores),0))

Output:

456

Lambda Expressions in python:

Lambda is a computer science term. Which is an anonymous function. Which don’t use more than once for a purpose. Usually in lambda we don’t need to decalre any function name. What happens inside a function we can write in simple line using lambda function.

lambda using map:

#lambda expressions
numbers=[1,2,3]
# def multiply_by2(item):
#     return item*2

#print(list(map(multiply_by2, numbers)))
print(list(map(lambda item: item*2, numbers))) # this line will be forgtten after run lambda param: action(param)

#lambda expressions

numbers=[1,2,3]

# def multiply_by2(item):

# return item*2

#print(list(map(multiply_by2, numbers)))

print(list(map(lambda item: item*2, numbers))) # this line will be forgtten after run lambda param: action(param)

lambda using filter:

#lambda expressions
numbers=[1,2,3]
print(list(filter(lambda item: item%2!=0, numbers))) # this line will be forgtten after run lambda param: action(param)

#lambda expressions

numbers=[1,2,3]

print(list(filter(lambda item: item%2!=0, numbers))) # this line will be forgtten after run lambda param: action(param)

lambda using reduce:

#lambda expressions
from functools import reduce
numbers=[1,2,3]
print(reduce(lambda acc,item: acc+item, numbers)) # this line will be forgtten after run lambda param: action(param)

#lambda expressions

from functools import reduce

numbers=[1,2,3]

print(reduce(lambda acc,item: acc+item, numbers)) # this line will be forgtten after run lambda param: action(param)

# Exercises using lambda
1. make a lambda example to squre

my_list=[5,4,3]
print(list(map(lambda item:item**2,my_list)))

1 2	my_list=[5,4,3] print(list(map(lambda item:item**2,my_list)))

2. make a lambda example to make a sorted list

a=[(0,2),(4,3),(9,9),(10,-1)]
print(list(filter(lambda item:sorted(a),a)))

a.sort(key=lambda x:x[1])
print(a)

a=[(0,2),(4,3),(9,9),(10,-1)]

print(list(filter(lambda item:sorted(a),a)))

a.sort(key=lambda x:x[1])

print(a)

List Comprehension

#list, comprehension
my_list=[]
for char in 'hello':
    my_list.append(char)

print(my_list)

#another rule with list comprehension using like that format below
#my_list=[param for param in iterable]
my_list=[char for char in 'hello']
my_list2=[num for num in range(0,100)]
my_list3=[num**2 for num in range(0,100)]
my_list4=[num**2 for num in range(0,100) if num%2==0]
print(my_list)
print(my_list2)
print(my_list3)
print(my_list4)

#list, comprehension

my_list=[]

for char in 'hello':

my_list.append(char)

print(my_list)

#another rule with list comprehension using like that format below

#my_list=[param for param in iterable]

my_list=[char for char in 'hello']

my_list2=[num for num in range(0,100)]

my_list3=[num**2 for num in range(0,100)]

my_list4=[num**2 for num in range(0,100) if num%2==0]

print(my_list)

print(my_list2)

print(my_list3)

print(my_list4)

Set and Dict Comprehension:

#set only allow numbers
# set only allow unique numbers or characters that is why out put has only once in 
my_list={char for char in 'hello'}
my_list2={num for num in range(0,100)}
my_list3={num**2 for num in range (0,100)}
my_list4={num**2 for num in range (0,100)}
print(my_list)
print(my_list2)
print(my_list3)
print(my_list4)

#set only allow numbers

# set only allow unique numbers or characters that is why out put has only once in

my_list={char for char in 'hello'}

my_list2={num for num in range(0,100)}

my_list3={num**2 for num in range (0,100)}

my_list4={num**2 for num in range (0,100)}

print(my_list)

print(my_list2)

print(my_list3)

print(my_list4)

#dict comprehension

#dict comprehension
simple_dict={
    'a':1,
    'b':2
}

#my_dict={key:value**2 for key,value in simple_dict.items()}
my_dict={k:v**2 for k,v in simple_dict.items() if v%2==0} #another way
my_dict1={num:num**2 for num in [1,2,3]} #different way to print dict
print(my_dict)
print(my_dict1)

#dict comprehension

simple_dict={

'a':1,

'b':2

}

#my_dict={key:value**2 for key,value in simple_dict.items()}

my_dict={k:v**2 for k,v in simple_dict.items() if v%2==0} #another way

my_dict1={num:num**2 for num in [1,2,3]} #different way to print dict

print(my_dict)

print(my_dict1)

Comprehension is for shorthand.

Now a small exercise:

Problem: to write a one line code to find duplicate character to show in a answer
Soln code:

some_list=['a','b','c','d','b','m','n','n']
duplicates=[]
# for value in some_list:
#     if some_list.count(value)>1:
#         if value not in duplicates:
#             duplicates.append(value)
duplicates=list(set([x for x in some_list if some_list.count(x)>1]))
print(duplicates)

some_list=['a','b','c','d','b','m','n','n']

duplicates=[]

# for value in some_list:

# if some_list.count(value)>1:

# if value not in duplicates:

# duplicates.append(value)

duplicates=list(set([x for x in some_list if some_list.count(x)>1]))

print(duplicates)

Output:

['b', 'n']

1	['b', 'n']

Decorators:

#decorators @classmethod @staticmethod it is start with @ sign
def hello():
    print('hellllooooo');

greet = hello
del hello #keywords del delete the function

print(greet())

#decorators @classmethod @staticmethod it is start with @ sign

def hello():

print('hellllooooo');

greet = hello

del hello #keywords del delete the function

print(greet())

another example:

#decorators @classmethod @staticmethod it is start with @ sign
def hello(func):
    func()

def greet():
    print('still here')

a=hello(greet)

print(a)

#decorators @classmethod @staticmethod it is start with @ sign

def hello(func):

func()

def greet():

print('still here')

a=hello(greet)

print(a)

Higher Order Function HOC

#higher order function(HOC)
def greet(func):
    func()
    
#filter(),map(),reduce(), all are higher order function
def greet2():
    def func():
        return 5
    return func

#higher order function(HOC)

def greet(func):

func()

#filter(),map(),reduce(), all are higher order function

def greet2():

def func():

return 5

return func

the decorator can supercharge the function and can add an extra feature

Decorator:

#decorator

def my_decorator(func):
    def wrap_func():
        print('******')
        func()
        print('******')
    return wrap_func

@my_decorator
def hello():
    print('helllooooo')

@my_decorator
def bye():
    print('Tschüß, see you later')

# hello()
# bye()

# a=my_decorator(hello)
# a()

# my_decorator(hello)()

#decorator

def my_decorator(func):

def wrap_func():

print('******')

func()

print('******')

return wrap_func

@my_decorator

def hello():

print('helllooooo')

@my_decorator

def bye():

print('Tschüß, see you later')

# hello()

# bye()

# a=my_decorator(hello)

# a()

# my_decorator(hello)()

Another example:

#Decorator
def my_decorator(func):
    def wrap_func(*args,**kwargs):
        print('*****')
        func(*args,**kwargs)
        print('*****')
    return wrap_func

@my_decorator
def hello(greeting, emoji=':('):
    print(greeting, emoji)

hello('hiii')

# a= my_decorator(hello)
# a('hiii',':)')
# hello('Hiii')

#Decorator

def my_decorator(func):

def wrap_func(*args,**kwargs):

print('*****')

func(*args,**kwargs)

print('*****')

return wrap_func

@my_decorator

def hello(greeting, emoji=':('):

print(greeting, emoji)

hello('hiii')

# a= my_decorator(hello)

# a('hiii',':)')

# hello('Hiii')

Practical Application of Decorator:

from time import time

def performance_time(fn):
	def wrapper(*args, **kwargs):
		t1=time()
		result=fn(*args,**kwargs)
		t2=time()
		print(f'took {t2-t1} seconds')
		return result
	return wrapper
	
@performance_time
def long_time():
	for i in range(100000000):
		i*5
		
long_time()

from time import time

def performance_time(fn):

def wrapper(*args, **kwargs):

t1=time()

result=fn(*args,**kwargs)

t2=time()

print(f'took {t2-t1} seconds')

return result

return wrapper

@performance_time

def long_time():

for i in range(100000000):

i*5

long_time()

while True:
    try: #the asking
        age=int(input('what is your age?'))
        #print(age)
        10/age #it is buggy if we give age 0
    except ValueError: #if there is error do this
        print('Please enter a number')
    except ZeroDivisionError:
        print('Please enter age higher than 0')

    else: #if there is no error do this
        print('Thank you')
        break

#continue

except ZeroDivisionError:

print('Please enter age higher than 0')

break

else:

print('thank you!')

break

finally:

print('ok, i am finally done')

print('can you hear me?')

custom error in error handling:

while True:
    try:
        age=int(input('What is your age?'))
        99/age
        #raise ValueError('Hey cut it out!')
        raise Exception('Hey cut it out!')
    except ZeroDivisionError:
        print('Please enter age higher than 0')
        #break
    else:
        print('thank you!')
       # break
    finally:
        print('ok, i am finally done')
    print('can you hear me?')

while True:

try:

age=int(input('What is your age?'))

99/age

#raise ValueError('Hey cut it out!')

raise Exception('Hey cut it out!')

except ZeroDivisionError:

print('Please enter age higher than 0')

#break

else:

print('thank you!')

# break

finally:

print('ok, i am finally done')

print('can you hear me?')
