使用tkinter Entry组件append数据后打印列表出现异常信息求助

你的问题核心是没有调用Entry组件的get()方法——你把方法对象本身(weather1.get)添加到了列表，而非执行方法获取输入框的实际内容。只有调用weather1.get()才能返回输入框中的文本值。

修正后的代码 #

import tkinter
from tkinter import messagebox

TemperatureInfo = []

weather = tkinter.Tk()
weather.geometry("200x300")
weather.update()
messagebox.showinfo("Weather App Explanation", "Hello! Welcome to my app that collects weather data! Input different aspects about the weather for the weekdays here and I will send back information on the data you entered!")

expln = tkinter.Label(weather, text = "Put the temperatures in here for Monday - Wednesday!").pack()
weather1 = tkinter.Entry(weather)
weather1.pack(pady = 10)
weather2 = tkinter.Entry(weather)
weather2.pack(pady = 10)
weather3 = tkinter.Entry(weather)
weather3.pack(pady = 10)
weather4 = tkinter.Entry(weather)
weather4.pack(pady = 10)
weather5 = tkinter.Entry(weather)
weather5.pack(pady = 10)

def addTempData():
    # 关键修正：给每个get()添加括号，执行方法获取输入内容
    TemperatureInfo.append(weather1.get())
    TemperatureInfo.append(weather2.get())
    TemperatureInfo.append(weather3.get())
    TemperatureInfo.append(weather4.get())
    TemperatureInfo.append(weather5.get())
    
def printInfo():
    print(TemperatureInfo)


done = tkinter.Button(weather, text = "Done", command = addTempData).pack()

printing = tkinter.Button(weather, text = 'print', command = printInfo).pack()

weather.mainloop()

额外建议 #

• 若不想多次点击"Done"时重复添加数据，可在addTempData函数开头加上TemperatureInfo.clear()清空列表
• 可以添加输入校验逻辑，比如把输入转为数值类型，避免非温度格式的内容存入列表
