map python documentation code example

Example 1: 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 2: python3 any

# True since 1,3 and 4 (at least one) is true
l = [1, 3, 4, 0]
print(any(l))

# False since both are False
l = [0, False]
print(any(l))

# True since 5 is true
l = [0, False, 5]
print(any(l))

# False since iterable is empty
l = []
print(any(l))

Example 3: função map python

lista =  [1, 2, -3, 4, 5, -9]
def quadrado(n):
    return n*n
 
map(quadrado, lista)
[1, 4, 9, 16, 25, 81]
