This article is about how to reload the function in python. The editor thinks it is very practical, so I share it with you. I hope you can get something after reading this article.

If you are used to writing Java or other object-oriented languages, you will often use function overloading.

The so-called function overloading means that the names and return value types of multiple functions are the same, only the parameter type or the number of parameters are different. Function overloading greatly improves the code reuse rate and programmer development efficiency.

But if you switch to python now, you may not be used to its formal inability to support function overloading. However, as an object-oriented language, python naturally does not lose the important feature of function overloading, which is common to object-oriented languages. The method of implementing function overloading in python is very special and interesting. Let's first look at the following function definition:

Def f (str,times):

Print str*times

The above function refers to printing times times to the string str, maybe you only need to print to str in many cases, so it is very tedious to assign a value of 1 to times each time. We want to print the value of times only once without specifying the value of string. In C++, you can do this with function overloading:

Void f (string str) {cout
