在 Tkinter 的文本框中保存和重新打开数据

Question

我在学校的最后一年，即 12 年级，我正在尝试制作一个我的客户能够打开的每周计划程序，将他们的数据输入到分配的文本框中，然后点击“保存”按钮并关闭窗口，当他们重新打开窗口时，他们之前输入的数据将已经存在。我已经创建了我的窗口、标题、文本框网格和一个“清除”按钮，用于清除文本框中的所有数据。我创建了“保存”按钮，但没有链接到它的命令。 这是我的代码：（它很长，其中大部分可能是不必要的，但它可以满足我的需求）：

from tkinter import Scale,Tk,Frame,Label,Button
from tkinter.ttk import Notebook,Entry,Button

root = Tk()
#title of the window
root.title('Orgnaiser')
#how big the window is in pixels
root.geometry("1700x700")


#program sets up a range of rows and columns:
for row in range(21):
    for column in range(7):#program then checks for the required info of row and column number
        if row==0 and column==0:#if these numbers match:
            label = Label(root, text="Monday")#the heading text of the first column will be "Monday",
            label.config(font=('comic sans ms', 16))#the font of the heading will be "comic sans ms"
            label.grid(row=row, column=column, sticky="nsew")
            root.grid_columnconfigure(column, weight=1)
        if row==0 and column==1:#repeats the same process as before but changes the heading text to "Tuesday",
            label = Label(root, text="Tuesday")# and moves it a column over to the right
            label.config(font=('comic sans ms', 16))
            label.grid(row=row, column=column, sticky="nsew")
            root.grid_columnconfigure(column, weight=1)
        if row==0 and column==2:#repeats the same process as before but changes the heading text to "Wednesday",
            label = Label(root, text="Wednesday")# and moves it a column over to the right
            label.config(font=('comic sans ms', 16))
            label.grid(row=row, column=column, sticky="nsew")
            root.grid_columnconfigure(column, weight=1)
        if row==0 and column==3:#repeats the same process as before but changes the heading text to "Thursday",
            label = Label(root, text="Thursday")# and moves it a column over to the right
            label.config(font=('comic sans ms', 16))
            label.grid(row=row, column=column, sticky="nsew")
            root.grid_columnconfigure(column, weight=1)
        if row==0 and column==4:#repeats the same process as before but changes the heading text to "Friday",
            label = Label(root, text="Friday")# and moves it a column over to the right
            label.config(font=('comic sans ms', 16))
            label.grid(row=row, column=column, sticky="nsew")
            root.grid_columnconfigure(column, weight=1)
        if row==0 and column==5:#repeats the same process as before but changes the heading text to "Saturday",
            label = Label(root, text="Saturday")# and moves it a column over to the right
            label.config(font=('comic sans ms', 16))
            label.grid(row=row, column=column, sticky="nsew")
            root.grid_columnconfigure(column, weight=1)
        if row==0 and column==6:#repeats the same process as before but changes the heading text to "Sunday",
            label = Label(root, text="Sunday")# and moves it a column over to the right

            label.grid(row=row, column=column, sticky="nsew")
            root.grid_columnconfigure(column, weight=1)

我对编码有点陌生，这是我唯一需要完成我的代码的事情。我将非常感谢任何可以帮助我解决这个问题的人，因为我已经坚持了一段时间。 谢谢。

对于您的规划器脚本，有两件事：

• 为网格创建条目对象列表。这比单独的变量更简洁（也更小）。
• 使用条目列表，遍历条目以将值保存\读取到 csv 文件

试试这个代码：

from tkinter import Scale,Tk,Frame,Label,Button
from tkinter.ttk import Notebook,Entry,Button

root = Tk()
#title of the window
root.title('Organiser')
#how big the window is in pixels
root.geometry("1700x700")

# create label for each day
daylist = ['Monday','Tuesday','Wednesday','Thursday','Friday','Saturday','Sunday']
for i,dy in enumerate(daylist):
    label = Label(root, text=dy)#the heading text of the first column will be "Monday",
    label.config(font=('comic sans ms', 16))#the font of the heading will be "comic sans ms"
    label.grid(row=0, column=i, sticky="nsew")
    root.grid_columnconfigure(i, weight=1)

entrylist = []  # list of all entry objects
for c in range(7):  # each column
   entrylist.append([])  # inner list for each row
   for r in range(10):  # each row
       a = Entry(root, text="")  # create entry object
       a.grid(row=r+1, column=c, padx=5, pady=5)
       entrylist[c].append(a)  # add to list

def clearTextInput():  # clear all entry boxes
    for c in entrylist:
        for r in c:
           r.delete("0", "end")

def save():
    import csv
    with open('plan.csv', 'w', newline='') as f:
        wr = csv.writer(f, quoting=csv.QUOTE_ALL)
        for r in range(10):
           lst = []  # create list for each row of data
           for c in range(7):  # each column
              lst.append(entrylist[c][r].get())
           wr.writerow(lst)  # write row to csv
    
def load():
    clearTextInput()  # prevent mixed text
    import csv
    with open('plan.csv') as f:  # read csv file
        rd = csv.reader(f)
        for r,data in enumerate(rd): # read single row (list)
           for c in range(7):  # each column
              entrylist[c][r].insert(0, data[c])  # fill in text box
   

load_button = Button(root, text ="Load", command=load)
load_button.grid(row=19, column=2, padx=10, pady=10)
   
save_button = Button(root, text ="Save", command=save)
save_button.grid(row=19, column=3, padx=10, pady=10)

clear_button = Button(root, text ="Clear", command=clearTextInput)
clear_button.grid(row=19, column=4, padx=10, pady=10)

root.mainloop()
