Python Lambda (Anonymous) Function Programiz Python allows you to create anonymous function i.e function having no names using a facility called lambda function. Lambda functions are small functions usually not more than a line. It can have any number of arguments just like a normal function. The body of lambda functions is very small and consists of only one expression.
What is lambda function in Python and why do we need it. Lambdas are one line functions. They are also known as anonymous functions in some other languages. You might want to use lambdas when you don’t want to use a function twice in a program. They are just like normal functions and even behave like them.
