Lambda functions in Python are small, anonymous functions defined using the lambda keyword. These functions can have any number of arguments but can only have a single expression. The result of the expression is implicitly returned. Lambda functions are often used in situations where a simple function is needed for a short period and is not reused elsewhere.

Syntax      

lambda arguments: expression

Example :

# Regular function to add two numbers

def add(x, y):

    return x + y

# Lambda function to add two numbers

add_lambda = lambda x, y: x + y

# Using both functions

result1 = add(5, 3)

result2 = add_lambda(5, 3)

print("Using regular function:", result1)   # Output: 8

print("Using lambda function:", result2)    # Output: 8
