如何在 PyCharm 中“查看"/突出显示选项卡和空格以检查缩进? [英] How to 'see' / highlight tabs and spaces in PyCharm for checking indentation?
问题描述
这听起来可能很愚蠢，但我还是个新手，是否有明确的方法可以发现 PyCharm 中的制表符或空格是否位于错误的位置?或者甚至可以直观地显示所有选项卡和空格?
this may sound dumb, but I am still fairly new, is there clear way to spot if I have tabs or spaces in the wrong place with PyCharm? Or even to display all tabs and spaces visually?
我花了很长时间在函数的 Def 行寻找无效语法"错误的问题，我原以为它可能仍然是一些错误的缩进，我以前确实有过，所以煞费苦心地检查了一下，但一无所获.最后，在此之前从函数结束处丢失了 ).我意识到右手边的彩色线条显示错误，并从那里得到了这个.
I just spent ages looking for problem with 'invalid syntax' error at Def line of function, I had thought it might still be some wrong indent, which I did have before, so checked this painstakingly and found nothing. In the end, was missing ) from end of function before this. I realised the coloured lines on right hand side show errors and got this one from there.
我也知道你可以在 PyCharm 中混合制表符和 4 个空格字符缩进没有问题?
Also I understand you can mix tabs and 4 space character indents in PyCharm with no problem?
但是，如果您在一行中使用制表符并在下一行中使用 4 个空格，例如，简单的文本编辑器，Python 会说‘不，我不会运行它，因为我是一个严格的学究，这太调皮了'?这方面还有其他常识性的最佳实践习惯吗?
But if you use tab one line and 4 spaces the next with, for example, simple text editor, Python will say 'no I'm not going to run this because I'm a strict pedant and this is just too naughty'? Any other common sense best practice habits in this area?

是的，你可以.但你不应该.但是，即使您选择这样做，默认情况下 PyCharm 也会将它们全部转换为空格.您可以通过转到设置 -> 编辑器 -> 代码样式 -> Python，然后选择使用制表符复选框来更改此行为:
Yes you can. But you shouldn't. Even if you choose to however, PyCharm will convert them all to spaces by default. You can change this behavior by going to Settings -> Editor -> Code Style -> Python and then selecting the Use tab character check box:
