python - 在 Python(或其他)GUI 中显示漂亮的 Python 代码

Question

我正在启动一个简单的小 GUI，用于给我学生的 Python 源代码评分。有没有一种简单的方法可以在 GUI 中自动格式化 python 代码的显示？例如，从某个编辑器中提取颜色格式？

我已经开始使用 Python tkk(只是为了一些额外的 python 练习，我教它但不经常使用它)但是如果在这方面更容易，我不反对切换语言。

输出将是一个包含所有成绩等的网页，但会使用 Google Prettify 显示 python 代码(除非有人有更好的建议)，所以我不需要保留配色方案，只需要显示它即可评分更容易。

非常感谢!

只记得 wxPython 与 SciTe 捆绑在一起:

#!/usr/bin/env python

import wx
from wx import stc
import keyword

class PyDialog(wx.Dialog):
    def __init__(self):
        wx.Dialog.__init__(self, None, -1, 'Python Code')
        sizer = wx.BoxSizer(wx.VERTICAL)

        self.stc = stc.StyledTextCtrl(self, -1)
        self.stc.SetSizeHints(400, 400)
        self.stc.SetLexer(stc.STC_LEX_PYTHON)
        self.stc.SetKeyWords(0, " ".join(keyword.kwlist))
        self.stc.SetMarginType(1, stc.STC_MARGIN_NUMBER)
        # Python styles
        self.stc.StyleSetSpec(wx.stc.STC_P_DEFAULT, 'fore:#000000')
        # Comments
        self.stc.StyleSetSpec(wx.stc.STC_P_COMMENTLINE,  'fore:#008000,back:#F0FFF0')
        self.stc.StyleSetSpec(wx.stc.STC_P_COMMENTBLOCK, 'fore:#008000,back:#F0FFF0')
        # Numbers
        self.stc.StyleSetSpec(wx.stc.STC_P_NUMBER, 'fore:#008080')
        # Strings and characters
        self.stc.StyleSetSpec(wx.stc.STC_P_STRING, 'fore:#800080')
        self.stc.StyleSetSpec(wx.stc.STC_P_CHARACTER, 'fore:#800080')
        # Keywords
        self.stc.StyleSetSpec(wx.stc.STC_P_WORD, 'fore:#000080,bold')
        # Triple quotes
        self.stc.StyleSetSpec(wx.stc.STC_P_TRIPLE, 'fore:#800080,back:#FFFFEA')
        self.stc.StyleSetSpec(wx.stc.STC_P_TRIPLEDOUBLE, 'fore:#800080,back:#FFFFEA')
        # Class names
        self.stc.StyleSetSpec(wx.stc.STC_P_CLASSNAME, 'fore:#0000FF,bold')
        # Function names
        self.stc.StyleSetSpec(wx.stc.STC_P_DEFNAME, 'fore:#008080,bold')
        # Operators
        self.stc.StyleSetSpec(wx.stc.STC_P_OPERATOR, 'fore:#800000,bold')
        # Identifiers. I leave this as not bold because everything seems
        # to be an identifier if it doesn't match the above criterae
        self.stc.StyleSetSpec(wx.stc.STC_P_IDENTIFIER, 'fore:#000000')

        # Caret color
        self.stc.SetCaretForeground("BLUE")
        # Selection background
        self.stc.SetSelBackground(1, '#66CCFF')

        sizer.Add(self.stc, 0, wx.EXPAND)

        button = wx.Button(self, -1, 'Open...')
        self.Bind(wx.EVT_BUTTON, self.OnOpen, button)
        sizer.Add(button)

        self.SetSizer(sizer)
        sizer.Fit(self)

    def OnOpen(self, evt):
        dlg = wx.FileDialog(
            self,
            message = 'Choose File',
            wildcard = 'Python source (*.py)|*.py',
            style = wx.OPEN)

        if dlg.ShowModal() != wx.ID_OK:
            return

        with open(dlg.GetPath()) as fo:
            self.stc.SetText(fo.read())

        dlg.Destroy()


if __name__ == '__main__':
    app = wx.PySimpleApp()
    dlg = PyDialog()
    with open(__file__) as fo:
        dlg.stc.SetText(fo.read())
    dlg.ShowModal()
