所以基本上它不会将我输入的内容写到我出错的文本文件中...... 我不得不尝试使用一个按钮,以便它可以在输入后写入 我应该在函数中而不是在for循环中写入条目
答案 0 :(得分:2)
首先需要在这里解决一些问题。
您在全局命名空间而不是函数中拥有Assignment Branch Condition size
和get()
。这将导致在extend()
处调用这2个方法,基本上,您将始终拥有空字符串。您想使用一个函数来调用这些东西,以便在需要时获取数据。
您的按钮命令还在__init__
上调用您的函数,因为您实际上并未保存对该函数的引用。要解决此问题,您需要去除括号或使用__init__
。
我会在lambda
上使用import tkinter as tk
。这样可以防止意外覆盖方法。
我将使用from tkinter import *
代替with open
和open()
。函数完成后,close()
语句将自动关闭文件。
下面,我对您的代码进行了一些整理,并添加了所需的更改。如果您有任何问题,请告诉我。
示例:
with
结果:
文件包含以下文本:
import tkinter as tk
root = tk.Tk()
write_list = []
tk.Label(root, text="Input your name: ").grid(column=1, row=0)
tk.Label(root, text="Enter your age:").grid(column=1, row=1)
name_entry = tk.Entry(root)
age_entry = tk.Entry(root)
name_entry.grid(column=2, row=0)
age_entry.grid(column=2, row=1)
def write_file():
name = name_entry.get()
age = age_entry.get()
write_list.extend(("Name:", name))
write_list.extend(("Age:", age))
with open("details.txt", "w") as my_file:
for x in range(len(write_list)):
write = write_list[x]
my_file.write(write)
my_file.write("\n")
tk.Button(root, text="Write to a file", command=write_file, bg="turquoise").grid(column=1, row=3)
root.mainloop()
