python - 在 python tkinter 上出现奇怪的缩进错误 - unindent 与任何外部缩进级别都不匹配
问题描述
我只是在出现缩进错误之前用 2 行代码添加 1 个 def。我正在尝试修改从 PAGE TkinterGUI 编辑器生成的用于登录消息框的代码。我真的不知道为什么会这样。
我在 youtube 上做了与这个人完全相同的代码，我试图将 def 移到最左边和最右边。
所以我要补充的是。def cancelLogin()在登录页面类中。它显示我的缩进错误def init()。请帮我解决这个问题。

没有“def cancelLogin()”它照常工作
实际结果：文件“./jta.py”，第 52 行 def init (self, top=None): ^ IndentationError: unindent does not match any external indentation level
解决方案
你可以试试：
grep -C 7 "__init" YOUR_FILE.py | tr ' \t' '.*'
这会将空格转换为点，将制表符转换为星号。然后你可以检查那里是否存在不匹配。
这是我在您发布的代码上尝试时的输出（来自问题源）：
$ grep -C 7 "__init" test.py | tr ' \t' '.*'
........w.=.None
....
....class.Login_page:
....
....*def.cancelLogin(self):
....**msg=tkMessageBox.askyesno("Login.page","Are.you.sure.,.you.want.to.cancel.login?")
....
........def.__init__(self,.top=None):
............'''This.class.configures.and.populates.the.toplevel.window.
...............top.is.the.toplevel.containing.window.'''
............_bgcolor.=.'#d9d9d9'..#.X11.color:.'gray85'
............_fgcolor.=.'#000000'..#.X11.color:.'black'
............_compcolor.=.'#d9d9d9'.#.X11.color:.'gray85'
............_ana1color.=.'#d9d9d9'.#.X11.color:.'gray85'.
............_ana2color.=.'#ececec'.#.Closest.X11.color:.'gray92'.
正如@tobias_k 所述，您添加的行中混合了制表符和空格。
