Python make it much faster !

#python programming today we will study map function to make functions run faster 

import time # we will record every function and make comparison of speed let go

time_at_this_moment_in_seconds=time.time()

def function1(listinput): #this is first example

 result=[]

 for element in listinput:                # or we can write  for first_argument,second_argument in listinput: and deleting this line "first_argument,second_argument=element "

   first_argument,second_argument=element   

   result.append(first_argument+second_argument)

 return result

short_list_as_input_for_exemple=[(1,2),(3,4),(5,6)]

short_list_made_longer=[(1,2),(3,4),(5,6)]*10

print("short_list_made_longer:",short_list_made_longer)

result_of_function1=function1([(1,2),(3,4),(5,6)]*1000)# let now make the input more longer and see how much second and comparison percents will change

print("result_of_function1:",result_of_function1)

time_once_first_function_finish=time.time()

time_that_took_the_function1_to_finish=time_once_first_function_finish-time_at_this_moment_in_seconds

   return  first_argument+second_argument

 return list(map(minifunction,listinput))

time_at_this_newmoment_in_seconds=time.time()

#Conclusion

#more we have longer list more we win time if we use map builtin function
