Following is the syntax of Python Lambda Function with if else inside another if else, meaning nested if else. You have to use the else statement as given in the method below. Hope now you will be able to play with the anonymous function and got understanding of lambda function in python. This is less like the for keyword in other programming languages, and works more like an iterator method as found in other object-orientated programming languages.. With the for loop we can execute a set of statements, once for each item in a list, tuple, set etc. Loop statements may have an else clause; it is executed when the loop terminates through exhaustion of the iterable (with for) or when the condition becomes false (with while), but not when the loop is terminated by a break statement.

In many other function that takes function as input argument, you can use anonymous function using lambda keyword. Can you elaborate? Python is having shorthand statements and shorthand operators. Summarizing this tutorial of Python Examples, we learned how to use if else or nested if else in lambda function to conditionally return values. Using a list comprehension might make for a cleaner use in 3.x: What's wrong with lambda x: x if x < 3 else None? See the following syntax. @ ubuntu -- thank you.
