A lambda function is an anonymous function (the function has no name), that excectues a single expression. An if-else block can be the one expression executed.
Solution for How to perform an if-statement inside a lambda function in Python : You can use an inline if-else expression to perform an if-statement inside a lambda function A lambda function behaves and runs the same as a one line function. The main differences are that the lambda function only takes up one line (arguments, and a single expression) so it is more compact to write, and lambda functions can be immediately invoked (i.e called and defined at the same time).
In the expression field of the lambda function declaration syntax:
lambda arguments : expression
Use the inline if-else expression syntax:
option 1 if condition else option 2
Where option 1 executes when condition results in True, otherwise option 2 is executed.
