Tkinter多Entry组件同步输入异常问题求助

你遇到的问题根源是所有Entry控件错误使用了text参数——Tkinter的Entry组件并没有text这个配置选项，当你传入text="test"时，会导致所有输入框意外共享同一个文本引用，进而出现输入内容同步的异常。

修复方案1：直接移除无效的text参数 #

这是最直接的修复方式，删除每个Entry的text="test"参数后，每个输入框会独立维护自身内容：

import tkinter as tk
window = tk.Tk()
window.title('Mortgage Calculator')
# How much is the property?
property_price = tk.Label(
    window, text="How much is the property? ", font=("Arial", 11))
property_price.pack(pady=10)
property_price_entry = tk.Entry(window, font=("Arial", 11))
property_price_entry.pack(pady=10)

# How much do you want to pay as a downpayment?
property_deposit = tk.Label(
    window, text="How much do you want to pay as a downpayment? ", font=("Arial", 11))
property_deposit.pack(pady=10)
property_deposit_entry = tk.Entry(window, font=("Arial", 11))
property_deposit_entry.pack(pady=10)

# How many years are you paying off your mortgage?
years_of_mortgage = tk.Label(
    window, text="How many years are you paying off your mortgage? ", font=("Arial", 11))
years_of_mortgage.pack(pady=10)
years_of_mortgage_entry = tk.Entry(window, font=("Arial", 11))
years_of_mortgage_entry.pack(pady=10)

# How much in interest are you paying?
interest = tk.Label(
    window, text="How much in interest are you paying? ", font=("Arial", 11))
interest.pack(pady=10)
interest_entry = tk.Entry(window, font=("Arial", 11))
interest_entry.pack(pady=10)

# Mortgage calculator button
monthly_mortgage_payment = tk.Label(
    window, text="Calculate monthly mortgage payments ", font=("Arial", 11))
monthly_mortgage_payment.pack(pady=10)
monthly_mortgage_payment_button = tk.Button(
    window, text="Calculate monthly mortgage payments ", font=("Arial", 11))
monthly_mortgage_payment_button.pack(pady=10)

window.mainloop()

修复方案2：使用textvariable绑定独立变量（如需默认文本） #

如果需要给输入框设置默认内容，可以为每个Entry绑定独立的StringVar对象，实现更灵活的文本控制：

import tkinter as tk
window = tk.Tk()
window.title('Mortgage Calculator')

# 为每个Entry创建独立的StringVar
price_var = tk.StringVar(value="")
deposit_var = tk.StringVar(value="")
years_var = tk.StringVar(value="")
interest_var = tk.StringVar(value="")

# How much is the property?
property_price = tk.Label(
    window, text="How much is the property? ", font=("Arial", 11))
property_price.pack(pady=10)
property_price_entry = tk.Entry(window, textvariable=price_var, font=("Arial", 11))
property_price_entry.pack(pady=10)

# How much do you want to pay as a downpayment?
property_deposit = tk.Label(
    window, text="How much do you want to pay as a downpayment? ", font=("Arial", 11))
property_deposit.pack(pady=10)
property_deposit_entry = tk.Entry(window, textvariable=deposit_var, font=("Arial", 11))
property_deposit_entry.pack(pady=10)

# How many years are you paying off your mortgage?
years_of_mortgage = tk.Label(
    window, text="How many years are you paying off your mortgage? ", font=("Arial", 11))
years_of_mortgage.pack(pady=10)
years_of_mortgage_entry = tk.Entry(window, textvariable=years_var, font=("Arial", 11))
years_of_mortgage_entry.pack(pady=10)

# How much in interest are you paying?
interest = tk.Label(
    window, text="How much in interest are you paying? ", font=("Arial", 11))
interest.pack(pady=10)
interest_entry = tk.Entry(window, textvariable=interest_var, font=("Arial", 11))
interest_entry.pack(pady=10)

# Mortgage calculator button
monthly_mortgage_payment = tk.Label(
    window, text="Calculate monthly mortgage payments ", font=("Arial", 11))
monthly_mortgage_payment.pack(pady=10)
monthly_mortgage_payment_button = tk.Button(
    window, text="Calculate monthly mortgage payments ", font=("Arial", 11))
monthly_mortgage_payment_button.pack(pady=10)

window.mainloop()
