map in python code example

Example 1: map in python 3

map(function, iterable, ...)

Example 2: map in python

'''try this instead of defining a function'''

a = [1,2,3,4]
a = list(map(lambda n: n+n, a))

print(a)

Example 3: map in python

#Syntax
map(functions, iterables)

Example 4: map in python

# Python program to demonstrate working 
# of map. 
  
# Return double of n 
def addition(n): 
    return n + n 
  
# We double all numbers using map() 
numbers = (1, 2, 3, 4) 
result = map(addition, numbers) 
print(list(result))
# result [2, 4, 6, 8]

Example 5: map in python

map(function_to_apply, list_of_inputs)

Example 6: map in python

>>> numbers = [1, 2, 3, 4, 5]
>>> squared = []

>>> for num in numbers:
...     squared.append(num ** 2)
...

>>> squared
[1, 4, 9, 16, 25]
