This article is about how to use python location parameters. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Description

1. Arguments must be transferred to the function in the correct order.

2. The number of actual parameters specified in the calling function must be the same as the number of formal parameters, otherwise the Python interpreter will throw a TypeError exception and indicate the lack of necessary location parameters.

Example

Def girth (width, height): when return 2 * width+height# calls a function, you must pass 2 parameters, otherwise it will cause an error print (girth (3)) and report a Traceback error after running. Traceback (most recent call last): File "/ Volumes/Develop/Python_learn/PycharmProjects/python_demo_1/demo/function/locate_fun.py", line 6, in print (girth (3)) TypeError: girth () missing 1 required positional argument: 'height' Thank you for reading!
