WebJul 28, 2024 · Python Function Syntax. The following snippet shows the general syntax to define a function in Python: def function_name(parameters): # What the function does goes here return result . You need to use the def keyword, give your function a name, followed by a pair of parentheses, and end the line with a colon (:). WebOn line 2, Python displays the value of the expression, which you can see is a function. The built-in Python function callable() returns True if the argument passed to it appears to be callable and False otherwise. Lines 4 and 5 show that the value returned by the lambda expression is in fact callable, as a function should be.
