Python re.search() vs re.match()用法及代码示例 先决条件:Python正则表达式 使用re.search()和re.match()- re.search()和re.match()两者都是repython中的模块。这些函数对于在字符串中搜索非常有效且快速。该函数在字符串中搜索一些子字符串,如果找到则返回匹配对象,否则不返回。 re.search()和re.match()-...

代码的 else 部分在 if 条件内,因为缩进是错误的。 修复Python中错误 IndentationError: unindent does not match any outer indentation level 空格和制表符的一致使用 虽然跟踪缩进听起来很乏味,但 PyCharm 和 VS Code 等代码编辑器具有内置功能,可帮助您跟踪缩进。

Now, you will be able to use VIM key combos not only in the shell but also in the Python interpreter and any other tool that uses GNU Readline (most database shells). Now you have VIM everywhere! Conclusion That’s more or less it (for Python development, at least). There are a to...
