# Python中的Goto函数及其替代方案在编程语言中,`goto`语句是一种直接跳转到程序中的另一部分的控制流语句。虽然C、BASIC等早期语言中都可以找到这一语句,但在现代编程中,尤其是在Python中,它被认为是一种不良实践,往往导致代码的可读性和维护性降低。本文将探讨Python中没有`goto`函数的原因,提供一些设计模式和结构...

Python 默认是没有 goto 语句的,但是有一个第三方库支持在 Python 里面实现类似于goto 的功能:https://github.com/snoack/python-goto.。比如在下面这个例子里,from goto import with_goto @with_goto def func(): for i in range(2): for j in range(2): goto 字节码 Python python 转载 mob64ca...
It's really strange that it's not able to initialise the python completer, as that's built in. What's more strange is that you say semantic completion is working with . ! That makes no sense to me. Can you confirm you used the minimal vimrc to repro this ? puremourning removed Wait...
