本文实例讲述了Python实现去除代码前行号的方法。分享给大家供大家参考。具体实现方法如下：
代码如下:
# -*- coding: utf-8 -*-
import wx
class MainWindow(wx.Frame):
def __init__(self, parent, id):
wx.Frame.__init__(self, parent, id,
u'去除代码前行号的Python小工具 - wxPython版 - Develop by Yanxy')
self.textBox = wx.TextCtrl(self, 1, style=wx.TE_MULTILINE,size=(600,600))
self.butOK = wx.Button(self, label=u"去除行号")
self.butLeft = wx.Button(self, label=u"去除左侧一个字符")
self.Bind(wx.EVT_BUTTON, self.CutLineNum, self.butOK)
self.Bind(wx.EVT_BUTTON, self.CutLeftChar, self.butLeft)
self.Bind(wx.EVT_CLOSE, self.OnCloseWindow)
self.sizer = wx.BoxSizer(wx.HORIZONTAL)
self.sizer.Add(self.textBox,1,wx.EXPAND)
self.sizer.Add(self.butOK)
self.sizer.Add(self.butLeft)
self.SetSizer(self.sizer)
self.SetAutoLayout(1)
self.sizer.Fit(self)
self.Show(True)
def OnCloseWindow(self, event):
self.Destroy()
def CutLineNum(self, event):
multiStr = unicode(self.textBox.GetValue()).splitlines(1)
outStr = u''
for singleStr in multiStr:
singleStr = singleStr.lstrip()
i=0
for charStr in singleStr:
if charStr.isdigit():
i += 1
elif i>0:
singleStr = singleStr[i:]
break
else:
break
outStr += singleStr
self.textBox.SetValue(outStr)
def CutLeftChar(self, event):
outStr = u''
multiStr = unicode(self.textBox.GetValue()).splitlines(1)
for singleStr in multiStr:
singleStr = singleStr[1:]
outStr += singleStr
self.textBox.SetValue(outStr)
if __name__ == '__main__':
app = wx.PySimpleApp()
frame = MainWindow(parent=None, id=-1)
app.MainLoop()
del app
希望本文所述对大家的Python程序设计有所帮助。
