In this article Xiaobian for you to introduce in detail the "python function two kinds of parameter transfer examples comparison", the content is detailed, the steps are clear, the details are handled properly, I hope this "python function two kinds of parameter transfer examples comparison" article can help you solve doubts, the following follow the editor's ideas slowly in-depth, together to learn new knowledge.

Comparison and explanation

1. One-to-one correspondence of the participating parameters in the position transfer, the location transfer parameters should be marked with the formal parameter names, which may not correspond to the formal parameters one by one, and the location transfer parameters must precede the keyword parameters.

The parameters are transferred strictly according to the position of the parameters, and the number of formal parameters and actual parameters must correspond.

2. The keyword parameter call function uses the formal parameter name to pass parameters, which can be different from the order of the formal parameter.
