Python Lambda Function

A lambda function is a small anonymous function.

A lambda function can take any number of arguments, but can only have one expression.

Syntax

lambda arguments : expression

The expression is executed and the result is returned:

A lambda function that adds 10 to the number passed in as an argument, and print the result:

x = lambda a : a + 10
print(x(5))

Lambda functions can take any number of arguments:

A lambda function that multiplies argument a with argument b and print the result:

x = lambda a, b : a * b
print(x(5, 6))

A lambda function that sums argument a, b, and c and print the result:

x = lambda a, b, c : a + b + c
print(x(5, 6, 2))
