in moduleC file in run file 注意Relative imports use a module’s name attribute to determine that module’s position in the package hierarchy. Note that relative imports are based on the name of the current module. 上述导入的过程是通过import mylib.sublib.moduleC找到moduleC.py文件,在该文件中...
When you selectRun Module, IDLE runs the script file ininteractive modeand drops you in a REPL environment. It’ll execute all the code in your file first, then allow you to continue interacting with the code. In that way, IDLE gives you the best of both worlds—interactive mode and fi...

Multiplication*: Copy n times to generate a new list/tuple Length len(): the number of elements in the list/tuple Index: name[i] Slice: name[start: end: step] Find: in(): Determine whether an element exists in the list/tuple
To determine which class a given object belongs to, you can use the built-in type():Python >>> type(miles) <class '__main__.JackRussellTerrier'> What if you want to determine if miles is also an instance of the Dog class? You can do this with the built-in isinstance():...
