Tkinter框架中的滚动条（python）

Question

I've had a little dilemma and I think that it might be the same for a few people(hopefully). The following code gets names from a text file in the same folder, then prints them out in a frame. Unfortunately I don't know how to add a scrolling functionality into just this frame (nameframe) . I need this code so that when you have a long list of names, all the names can be seen. Currently you can only see half of the names. I also would like the buttons to be the same size.

from tkinter import *
import time
import datetime
import re

root = Tk()
root.title("Attendence Register")
root.geometry('1350x650+0+0')

root.resizable(False, False)

nameframe = Frame(root, height=650, width=300)
nameframe.pack(side='left')

saveframe = Frame(root, height=650, width=300)
saveframe.pack(side='right')

outlist = []

def saveDataPresent(line):
    presentcount[line] += 1

    if presentcount[line] %2 == 1:
        present[line].configure(bg='#ff4dd2')
        line = (line + ' is present')
        outlist.append(line)
        #print(outlist)

    else:
        present[line].configure(bg='#66ff66')
        line = (line + ' is present')
        outlist.remove(line)
        #print(outlist)

def saveDataAbsent(line):
    absentcount[line] += 1

    if absentcount[line] % 2 == 1:
        absent[line].configure(bg='#ff4dd2')
        line = (line + ' is absent')
        outlist.append(line)
        #print(outlist)

    else:
        absent[line].configure(bg='#ff6666')
        line = (line + ' is absent')
        outlist.remove(line)
        #print(outlist)

def saveDataIll(line):
    illcount[line] += 1

    if illcount[line] % 2 == 1:
        ill[line].configure(bg='#ff4dd2')
        line = (line + ' is ill')
        outlist.append(line)
        #print(outlist)

    else:
        ill[line].configure(bg='#ffa31a')
        line = (line + ' is ill')
        outlist.remove(line)
        #print(outlist)

def saveDataHoliday(line):
    holidaycount[line] += 1

    if holidaycount[line] % 2 == 1:
        holiday[line].configure(bg='#ff4dd2')
        line = (line + ' is holiday')
        outlist.append(line)
        #print(outlist)

    else:
        holiday[line].configure(bg='light blue')
        line = (line + ' is holiday')
        outlist.remove(line)
        #print(outlist)

def saveData():
    now = datetime.datetime.now()
    now = str(now)
    dire = 'logs/'
    now = dire + now

    now = re.sub(':', '', now)
    now += '.txt'

    log = open(now, "w+")
    log.close()
    log = open(now, "a")
    for i in outlist:
        i = (i + '\n')
        log.write(i)
    log.close()

text = open('names.txt','r')
line = text.readline()
count = 0
present = {}
absent = {}
ill = {}
holiday = {}

presentcount = {}
absentcount = {}
illcount = {}
holidaycount = {}

for line in text:
    count+= 1
    name = Label(nameframe, text=line)
    name.grid(row=count, column = 0)

    presentcount[line] = 0
    absentcount[line] = 0
    illcount[line] = 0
    holidaycount[line] = 0


    present[line] =  Button(nameframe, text='/', pady = 20, padx=20, bg ='#66ff66', command=lambda line=line: saveDataPresent(line))
    present[line].grid(row=count, column = 2)

    holiday[line] = Button(nameframe, text='H', pady=20, padx=20, bg='light blue', command=lambda line=line: saveDataHoliday(line))
    holiday[line].grid(row=count, column=3)

    ill[line] = Button(nameframe, text='ill', pady=20, padx=20, bg ='#ffa31a', command=lambda line=line: saveDataIll(line))
    ill[line].grid(row=count, column=4)

    absent[line] = Button(nameframe, text='NA', pady=20, padx=20, bg ='#ff6666', command=lambda line=line: saveDataAbsent(line))
    absent[line].grid(row=count, column=5)

savebut = Button(saveframe, text='Save', pady = 20, padx=20, command=saveData)
savebut.pack()

root.mainloop()

Thanks for any help I hope my question is clear. In summary, I would like to know how to add a functioning scroll bar, or atleast something to help to be able to see all the names. This scroll bar should only affect nameframe . To show my situation more clearly: Image of the frame cutting

This is the sort of thing that I'm looking for:

nameframe = Frame(root, height=650, width=300)
nameframe.pack(side='left')

vsb = Scrollbar(orient="vertical", command=nameframe.yview)
nameframe.configure(yscrollcommand=vsb.set)

saveframe = Frame(root, height=650, width=300)

This commes up with the error: 'Frame' object has no attribute 'yview' saveframe.pack(side='right')

As pointed out in the link I provided you need to be using a canvas to scroll over widgets by adding a frame window to the canvas. There is also this post that may better explain what to do here: Adding a scrollbar to a group of widgets in Tkinter .

My example is only to solve the problem of scrolling through your widgets. Please note you may have other issues to review.

I prefer to use grid() manager so I updated your code accordingly. Please let me know if you have any questions.

Here is your code updated (with some general cleanup):

import tkinter as tk

root = tk.Tk()
root.title("Attendence Register")
root.geometry('1350x650+0+0')
root.resizable(False, False)

root.rowconfigure(0, weight=1)
saveframe = tk.Frame(root, height=650, width=300)
saveframe.grid(row=0, column=2)

    presentcount[line] += 1

        outlist.append(line)
    else:

        line = (line + ' is present')
        outlist.remove(line)

    if absentcount[line] % 2 == 1:
