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
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
