In Python, the lambda keyword is used to create anonymous functions, or functions without a name. These functions can be used in place of a named function to provide a simple, one-line expression.

The syntax for a lambda function is:

lambda arguments: expression

where arguments are the input parameters to the function, and expression is the output of the function.

For example, the following lambda function takes two arguments and returns their sum:

sum = lambda a, b: a + b

Lambda functions can be assigned to a variable, passed as an argument to another function, or used as a return value for another function. They are commonly used when a simple operation is needed and defining a full function is not necessary.

Here is an example of using a lambda function in Python:

#A lambda function that adds two numbers

addition = lambda x, y : x + y

Use the lambda function

result = addition(5, 3)

Print the result

print(result) # Output: 8
