python tkinter 输不出结果”TypeError: 'str' object cannot be interpreted as an integer“

Question

想要输出类似于”A112“的字符串所代表的储物架位置，但是发现函数无法使用

from tkinter import *
from tkinter import messagebox
text1=r=''
x=5
window = Tk()
window.title("First Window")
window.geometry("350x200")
lbl = Label(window, text="Hello")
lbl.grid(column=0, row=0)
txt = Entry(window, width=10)
txt.grid(column=1, row=0)
txt2=Label(window, text="output")
txt2.grid(column=1, row=1)
def searching():
    for i in range(r):
        south=["Z","Y","X","W","V","U","T","S","R","Q","P","O","M","N","L","K","J",]
        middle=["H"]
        north=["A","B","C","D","E","F","G"]
        x=input("请输入序列号（斜杠前字母大写）")
        a1=x[0]
        a2=x[1]
        if a1=='G':
            if '5' >= a2 >='0':
                text3 = "北架"
                txt2.configure(text=text3)
            else:
                text3="中架"
                txt2.configure(text=text3)
        elif a1=='I':
            text3='人工操作'
            txt2.configure(text=text3)
        elif a1 in south:
            text3="南架"
            txt2.configure(text=text3)      
        elif a1 in middle:
            text3="中架"
            txt2.configure(text=text3)
        elif a1 in north:
            text3="北架"
            txt2.configure(text=text3)
        else:
            text3="请再确认编号"
            txt2.configure(text=text3)
btn = Button(window, text="searching", command=searching)
btn.grid(column=2, row=0)
window.mainloop()

调用之后就提示”TypeError: 'str' object cannot be interpreted as an integer“
希望有朋友能够提供帮助！

      for i in range(r):

这个r是空字符串啊。你想用for循环什么啊？
如果不需要循环把 for i in range(r): 这行去掉就好
