Tkinter Text 文本框控件具有 delete(first, last=None) 方法，可从文本框中删除 first 索引处或 (first, last) 范围内的字符。
如果未给出 last，则仅删除在 first 位置中指定的字符。
清除 Tkinter 文本控件内容的示例代码
import tkinter as tk
root = tk.Tk()
root.geometry("400x240")
def clearTextInput():
textExample.delete("1.0","end")
textExample=tk.Text(root, height=10)
textExample.pack()
btnRead=tk.Button(root, height=1, width=10, text="Clear",
command=clearTextInput)
btnRead.pack()
root.mainloop()
textExample.get("1.0", "end")
"1.0"和"end"是指 Tkinter 文本框控件中内容的第一个字符和最后一个字符，与如何获取文本的输入的文章中介绍的内容相同。
