How do I use the map function with lists in Python?
The map
function applies a given function to all items in an input list. Would you like an example?
Yes, please provide an example.
Sure! Here's a simple example:
numbers = [1, 2, 3, 4]
result = list(map(lambda x: x * 2, numbers))
print(result) # Output: [2, 4, 6, 8]
This doubles each number in the list.
What if I want to use a defined function instead of a lambda?
You can definitely use a defined function! For example:
def double(x):
return x * 2
result = list(map(double, numbers))
print(result) # Output: [2, 4, 6, 8]
