[wxPython] Python string insertion problem with wxListCtrl

Referin to George email I tried to change the subject
of my question.

This is the code:
for sum_of_data in range(total):
    
self.list.SetStringItem(sum_of_data,0,grade[sum_of_data][0])
    
self.list.SetStringItem(sum_of_data,1,grade[sum_of_data][1])

When running this codes I got Error:

TypeError: String or Unicode type nedded

Help me please & thanx to George!!!

This is the code:
for sum_of_data in range(total):

self.list.SetStringItem(sum_of_data,0,grade[sum_of_data][0])

self.list.SetStringItem(sum_of_data,1,grade[sum_of_data][1])

When running this codes I got Error:

TypeError: String or Unicode type nedded

Well, what is the type of "grade[sum_of_data][0]" ? If it's not a string
then you need to convert it to one before calling the method.

BTW, The first column of each item in a list ctrl needs to be created with
InsertStringItem. You can then use SetStringItem for the remaining columns
of the item. See the demo for an example.

This is the code again:

        self.list = wxListCtrl(self, tID,
style=wxLC_REPORT|wxSUNKEN_BORDER)#|wxLC_VRULES|wxLC_HRULES)

        if 0:
            self.list.InsertColumn(0, "ID")
            self.list.InsertColumn(1, "Name",
wxLIST_FORMAT_CENTER)
        else:
            info = wxListItem()
            info.m_mask = wxLIST_MASK_TEXT |
wxLIST_MASK_FORMAT
            info.m_format = 0
            info.m_text = "ID"
            self.list.InsertColumnInfo(0, info)

            info.m_format = wxLIST_FORMAT_CENTER
            info.m_text = "Name"
            self.list.InsertColumnInfo(1, info)
            
            total = len(self.Kueri())
            grade = self.Kueri()
            
        for sum_of_data in range(total):
            self.list.SetStringItem(sum_of_data, 0,
grade[sum_of_data][0])
            self.list.SetStringItem(sum_of_data, 1,
grade[sum_of_data][1])

    def Kueri(self):
        s = odbc.odbc('mysql/user/passwd')
        cur = s.cursor()
        cur.execute('select * from user')
        rec = cur.fetchall()
        return rec

I took this code from the demo of wxListCtrl & it
didn;t say anything about InsertStringItem before
SetStringItem. I don't know if the
grade[sum_of_data][0]
type is string or else I just know that it was the
data taken from the database (def Kueri()).

SetStringItem.

Yes it does, look again. (Well, it uses InsertImageStringItem, which is
just another overloaded name for InsertItem.)

I don't know if the
grade[sum_of_data][0]
type is string or else I just know that it was the
data taken from the database (def Kueri()).

Well, since you are getting a "TypeError: String or Unicode type nedded" you
can be certain that it is not a string (or unicode). You can add a "print
type(grade[sum_of_data][0])" (and one for *[1] too) to find out what it
really is if you are interested. Convert it to a string and the error will
go away.
