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.
