学ぶ Lambda Functions in Python

メニューを表示するにはスワイプしてください

All the functions you've created so far are stored in memory after running the code for the first time. However, sometimes you may not want to define a separate function especially for simple, straightforward tasks. In these cases, lambda function can be useful, as it creates anonymous functions.

lambda var1, var2, ... : expression

But not all functions discussed can be converted into lambda functions. Typically, lambda functions are best suited for concise operations that fit within a single line.


              12345
            
# Define lambda function
sum_squared = lambda x, y: (x + y) ** 2

# Test
print('Sum of 2 and 3 squared is', sum_squared(2, 3))

すべて明確でしたか？
