Learn Python Lambda Functions with Example

Python lambda function is a small anonymous function without a name. It can take any number of arguments but only have one expression.

Here, arguments is a comma-separated list of arguments and expression is a single-line expression that is evaluated and returned by the lambda function.

For example, consider the following lambda function that adds two numbers:

Generally, Lambda functions are used with higher-order functions such as map, filter, and reduce.

consider the following code that uses the map function to apply the lambda function to a list of numbers:

We can also use lambda functions with the filter function to select elements that satisfy a certain condition.

we can use the reduce function from the functools module to perform a reduction operation on a sequence of elements.

Define a lambda function that calculates the square of a number

Overall, lambda functions are a powerful tool in Python that can help you write cleaner, more efficient code.
