This article mainly introduces the relevant knowledge of "the method of python string search and replacement". The editor shows you the operation process through the actual case. The operation method is simple, fast and practical. I hope this article "the method of python string search and replacement" can help you solve the problem.

Find

Instr (parameter 1, parameter 2, parameter 3, parameter 4)

Parameter 1: search from left to right by default. This parameter indicates the location where the search starts. The default is 1.

Parameter 2: represents the source string

Parameter 3: represents the string to find

Parameter 4: represents the way to find it, here we use vbbinarycompare

Vbbinarycompare returns the location found by the string, and returns 0 if it is not found

The selection function of Textbox control

Text1.SetFocus' set focus

Text1.SelStart = pos-1 'Note this is where the cursor starts

Text1.SelLength = Len (Text2.Text) 'Select a few characters back from the cursor

Replace function

Replacement function

Replace (source string, string to find, which string to replace)

Return result: return the string after the source string has been replaced

Software design interface:

Source code sharing:

Private Sub Command1_Click (Index As Integer) 'Note If Command1 (Index). Caption = "find" Then Dim pos& pos = InStr (1, Text1.Text, Text2.Text, vbBinaryCompare) Text1.SetFocus' set focus Text1.SelStart = pos-1 Text1.SelLength = Len (Text2.Text) ElseIf Command1 (Index). Caption = "replace" Then Text1.Text = Replace (Text1.Text, Text2.Text, Text3.Text)

End If

End Sub
