python - 使用 tkinter 窗口生成 CSV 文件

Question

我正在尝试创建 CSV 生成器，它将为我将提供给他的用户列表生成 csv 文件。生成的行应如下所示：

add;[e-mail];Rolename1
add;[e-mail];Rolename2
add;[e-mail];Rolename1
add;[e-mail];Rolename2

这是如果我选择角色 1 和 2 的复选框，它将为用户添加具有这两个角色的行。到目前为止，我必须生成文件，但我现在的主要问题是我不知道如何让它从 tkinter Text 读取用户，然后将其保存到 csv 中。我希望它只接受 AZ 和 0-9 作为用户名。到目前为止，这是我的代码：

from tkinter import *
from tkinter import ttk
import datetime
import pandas as pd

root = Tk()
root.geometry('500x500')
root.title("Csv generator")
#Creator name
creator = Entry(root, width=23)
creator.grid(column=1,row=0)
creator.insert(0, "Enter here your username")

#Functions entry

functionLabel = Label(root, text="FUNCTION", width=10).grid(column=0, row=1, padx=10)
clickFunction = StringVar()
clickFunction.set("Select your function")
Function = OptionMenu(root, clickFunction, "add", "chg", "cho", "del")
Function.grid(column=0, row=2, padx=10)

#Username list

usernameLabel = Label(root, text="USERNAME",width=10)
usernameLabel.grid(column=1, row=1, padx=10)
usernameList = Text(root, width=10, height=4)
usernameList.grid(column=1, row=1, padx=10, rowspan=4)

#Role List
rolesLabel = Label(root, text="ROLES", width=10)
rolesLabel.grid(column=2, row=1, padx=10)
rolesCheck1 = StringVar()
role1 = Checkbutton(root, text="Role01", variable=rolesCheck1, onvalue="Role01", offvalue="")
role1.grid(column=2, row=2, padx=10)
rolesCheck2 = StringVar()
role2 = Checkbutton(root, text="Role02", variable=rolesCheck2)
role2.grid(column=2, row=3, padx=10)
rolesCheck3 = StringVar()
role3 = Checkbutton(root, text="Role1", variable=rolesCheck3)
role3.grid(column=2, row=4, padx=10)
rolesCheck4 = StringVar()
role4 = Checkbutton(root, text="Role2", variable=rolesCheck4)
role4.grid(column=2, row=5, padx=10)

#Read Textbox
def usersout():
    inputvalue = usernameList.get("1.0","end-1c")
    print(inputvalue)
#CSV Creator part
def csvGenerate():
    basename= creator.get()
    suffix = datetime.datetime.now().strftime("%Y%m%d%H%M.csv")
    filename = "_".join([basename, suffix]) # e.g. 'Creator_120508171442'
    df = pd.read_csv('Template.csv')
    df2 = df.append(usernameList, ignore_index=True)
    df.to_csv(filename, index=False, header=False)

#Generate button

GENERATE = Button(root, text="GENERATE", command=csvGenerate).grid(column=0, row=6, columnspan=3)

root.mainloop()

编辑 20.10.2021：按照建议将我的代码从 csv 更改为 pandas，但仍然不知道如何继续。

我建议使用 for 循环创建检查按钮，并将这些StringVars 存储在一个列表中，以后可以很容易地使用它来确定选择了哪些角色。

请注意，csv使用 module 而不是pandas：

from tkinter import *
from tkinter import ttk
import datetime
import csv

root = Tk()
root.geometry('500x500')
root.title("Csv generator")
#Creator name
creator = Entry(root, width=23)
creator.grid(column=1, row=0)
creator.insert(0, "Enter here your username")

#Functions entry

Label(root, text="FUNCTION", width=10).grid(column=0, row=1, padx=10)
clickFunction = StringVar(value="Select your function")
OptionMenu(root, clickFunction, "add", "chg", "cho", "del").grid(column=0, row=2, padx=10)

#Username list

Label(root, text="USERNAME", width=10).grid(column=1, row=1, padx=10)
usernameList = Text(root, width=10, height=4)
usernameList.grid(column=1, row=1, padx=10, rowspan=4)

#Role List
Label(root, text="ROLES", width=10).grid(column=2, row=1, padx=10)
role_vars = [] # for storing those StringVars
# create the checkbuttons
for row, role in enumerate(("Role01", "Role02", "Role1", "Role2"), 2):
    var1 = StringVar()
    Checkbutton(root, text=role, variable=var1, onvalue=role, offvalue='').grid(row=row, column=2, padx=10, sticky='w')
    role_vars.append(var1)

#CSV Creator part
def csvGenerate():
    basename = creator.get()
    suffix = datetime.datetime.now().strftime("%Y%m%d%H%M.csv")
    filename = "_".join([basename, suffix]) # e.g. 'Creator_202110211234.csv'
    with open(filename, "w", newline="") as file:
        writer = csv.writer(file)
        func = clickFunction.get() # use the StringVar instead
        # get user list
        users = usernameList.get('1.0', 'end-1c').splitlines()
        # get selected roles
        roles = [role.get() for role in role_vars if role.get()]
        for user in users:
            for role in roles:
                writer.writerow([func, user, role])

#Generate button
Button(root, text="GENERATE", command=csvGenerate).grid(column=0, row=6, columnspan=3)

root.mainloop()
