使用 GUI 写入 CSV 文件单元格答案

【问题描述】：

我正在尝试制作一个将写入 CSV 文件的 GUI。我希望输入框中的任何内容都写入相应的单元格。

我想在 CSV 中查看的条目示例如下：

vlan 8
192.168.1.1 255.255.255.0
fa2/0/1

但是，当我打开 data1.csv 时，它写道：

PY_VAR0
PY_VAR1
PY_VAR2

这是我写的python代码：

import csv
from tkinter import *

root = Tk()
root.geometry('300x300')
root.title("Cisco-Oneport")
photo = PhotoImage(file = "Logo.PNG")
root.iconphoto(False, photo)

def info():
    list_of_lists = [[f'{vlan}',],
                    [f'{ip}',],
                    [f'{port}',]]

    with open('data1.csv', 'w', newline='') as f:
        writer = csv.writer(f, delimiter=';')
        for sublist in list_of_lists:
            writer.writerow(sublist)

entry1_text = Label(text = "Type Vlan Number * ",)
entry2_text = Label(text = "Type IP Number and Subnet * ",)
entry3_text = Label(text = "Type in Fast Port * ",)

entry1_text.place(x = 15, y = 30)
entry2_text.place(x = 15, y = 90)
entry3_text.place(x = 15, y = 150)

vlan = StringVar()
ip = StringVar()
port = StringVar()

vlan_entry = Entry(textvariable = vlan, width = "10")
ip_entry = Entry(textvariable = ip, width = "30")
port_entry = Entry(textvariable = port, width = "10")

vlan_entry.place(x = 15, y = 60)
ip_entry.place(x = 15, y = 120)
port_entry.place(x = 15, y = 180)


register = Button(root,text = "Run", width = "10", height = "2", command = info, bg = "lightgreen")
register.place(x = 15, y = 240)

root.mainloop()

如何获得所需的输入？我对轻量级 GUI 编码还很陌生。

.csv 文件显示StringVars 的 tcl/tk 名称。使用 .get() 获取值。标签和条目是在没有包含对象的情况下创建的，所以我看到一个带有文本的 GUI，而另一个带有运行按钮的 GUI。

回答可以在控制台中复制和运行代码的问题更容易。因此，最好删除图标之类的东西，这些东西使用了另一台 PC 上不存在的文件。

import csv
from tkinter import *

root = Tk()
root.geometry('300x300')
root.title("Cisco-Oneport")

# Removed icon as I cant access the file

# Use .get() to get the values of the StringVars, not the names of the StringVars
def info():
    list_of_lists = [[f'{vlan.get()}',],
                    [f'{ip.get()}',],
                    [f'{port.get()}',]]

    with open('data1.csv', 'w', newline='') as f:
        writer = csv.writer(f, delimiter=';')
        for sublist in list_of_lists:
            writer.writerow(sublist)

# Add root to put the all the objects in the same GUI
entry1_text = Label(root, text = "Type Vlan Number * ",)
entry2_text = Label(root, text = "Type IP Number and Subnet * ",)
entry3_text = Label(root, text = "Type in Fast Port * ",)

entry1_text.place(x = 15, y = 30)
entry2_text.place(x = 15, y = 90)
entry3_text.place(x = 15, y = 150)

vlan = StringVar()
ip = StringVar()
port = StringVar()

# Add root to put the all the objects in the same GUI
vlan_entry = Entry(root, textvariable = vlan, width = "10")
ip_entry = Entry(root, textvariable = ip, width = "30")
port_entry = Entry(root, textvariable = port, width = "10")

vlan_entry.place(x = 15, y = 60)
ip_entry.place(x = 15, y = 120)
port_entry.place(x = 15, y = 180)

# 
register = Button(root,text = "Run", width = "10", height = "2", command = info, bg = "lightgreen")
register.place(x = 15, y = 240)

root.mainloop()
