问题

例如，我想要使用循环从1到10依次将数字插入到我创建的10个条目中，从开始到结束。

from tkinter import *

root = Tk()
root.title("")
root.geometry("500x400")
canvas = Canvas(root, width=450, height=350, highlightbackground="black")

for i in range(40, 240, 21):
entry = Entry(root, width=10)
entry_window = canvas.create_window(50, i, anchor="nw", window=entry)
entry.insert(0, 1)

canvas.pack()
root.mainloop()

For example, I want to insert the numbers from 1 to 10, respectively, from the beginning to the end, into the 10 entries I created with a loop.

from tkinter import *

root = Tk()
root.title("")
root.geometry("500x400")
canva = Canvas(root,width=450,height=350,highlightbackground="black")

for i in range(40, 240, 21):
Abent = Entry(root, width=10)
Abentry = canva.create_window(50, i, anchor="nw", window=Abent)
Abent.insert(0,1)

canva.pack()
root.mainloop()

你可以通过在你的`for`循环的可迭代对象上使用[enumerate](https://docs.python.org/3/library/functions.html?#enumerate)来完成这个操作。
```python
for index, y_pos in enumerate(range(40, 240, 21)):  # 在范围上使用enumerate
    abent = Entry(root, width=10)
    abentry = canva.create_window(50, y_pos, anchor="nw", window=abent)
    abent.insert(0, index)

另外，为了符合PEP8的规范，我已经将你的变量重命名为小写名称！供以后参考，大写名称通常用于类，如Entry。

for index, y_pos in enumerate(range(40, 240, 21)):  # enumerate over range
    abent = Entry(root, width=10)
    abentry = canva.create_window(50, y_pos, anchor="nw", window=abent)
    abent.insert(0, index)
