Python Tkinter开发报错：TextIOWrapper.write()参数数量不匹配求助

错误原因 #

• f.write() 方法仅支持接收单个字符串参数，你代码中同时传入了输入框对象、换行符等共16个参数，直接触发 TypeError 报错。
• Entry(sign).place(xxx) 的写法错误，place() 方法无返回值，执行后 e1 到 e8 变量全部为 None，即使修复传参问题也无法拿到用户输入的内容。
• 写文件的逻辑直接放在窗口初始化代码后，程序运行时会在窗口弹出的瞬间就执行写文件操作，不会等待用户输入后点击提交按钮触发。
• 字符串形式的Windows文件路径未做转义处理，路径中的特殊字符可能被识别为转义符导致文件打开失败。

import tkinter as tk
from tkinter import *

def sign_in():
    sign = tk.Tk()
    sign.title("Learn English To Study Abroad - LETSA  |  v0.0.1")
    sign.geometry("300x210")

    Label(sign, text = "Your Account: ").place(x = 0, y = 0)
    Label(sign, text = "Your Fullname: ").place(x = 0, y = 20)
    Label(sign, text = "Your age: ").place(x = 0, y = 40)
    Label(sign, text = "Your birthday: ").place(x = 0, y = 60)
    Label(sign, text = "Your Email address: ").place(x = 0, y = 80)
    Label(sign, text = "Your Phone number (Optional): ").place(x = 0, y = 100)
    Label(sign, text = "Your Password: ").place(x = 0, y = 120)
    Label(sign, text = "Re-Your password: ").place(x = 0, y = 140)

    # 先创建Entry对象，再调用place方法，保证变量存储的是输入框实例
    e1 = Entry(sign)
    e1.place(x = 85, y = 0)
    e2 = Entry(sign)
    e2.place(x = 90, y = 20)
    e3 = Entry(sign)
    e3.place(x = 60, y = 40)
    e4 = Entry(sign)
    e4.place(x = 80, y = 60)
    e5 = Entry(sign)
    e5.place(x = 110, y = 80)
    e6 = Entry(sign)
    e6.place(x = 175, y = 100)
    e7 = Entry(sign)
    e7.place(x = 90, y = 120)
    e8 = Entry(sign)
    e8.place(x = 110, y = 140)

        ]) + '\n'
        # 路径加r前缀标记为原始字符串，避免转义问题
