Python map() function

map() function returns a list of the results after applying the given function to each item of a given iterable (list, tuple etc.)

Syntax :

map(fun, iter)

 

Returns :

Returns a list of the results after applying the given function
to each item of a given iterable (list, tuple etc.)

Returns :

Returns a list of the results after applying the given function

to each item of a given iterable (list, tuple etc.)

				
					def addition(n): 
    return n + n 
    
# We double all numbers using map() 
numbers = (1, 2, 3, 4) 
result = map(addition, numbers) # map(function,Structre)
print(result)
print(tuple(result)) 
				
			
				
					#Example
#Calculate the length of each word in the tuple:

def myfunc(n):
  return len(n)

x = map(myfunc, ('apple', 'banana', 'cherry'))
#convert the map into a list, for readability:
print(list(x))

					# Add two lists using map and lambda 
  
numbers1 = [1, 2, 3] 
numbers2 = [4, 5, 6] 
  
result = map(lambda x, y: x + y, numbers1, numbers2) 
print(list(result)) 
				
			
				
					# Research and give me the answer and Explain me also that
# List of strings 
l = ['sat', 'bat', 'cat', 'mat'] 
  
# map() can listify the list of strings individually 
test = list(map(list, l)) 
print(test)
