1.文件打开和保存的选择框

选择文件例子

from tkinter.filedialog import askopenfilename# 弹出文件选择对话框选择一个文件
read_file_name = askopenfilename()
if read_file_name != '':print("you can read from " + read_file_name)file1 = open(read_file_name, "r", encoding="utf-8")s = file1.read()print(s)
else:print("你未选择一个文件")

手动选择文件的例子

from tkinter.filedialog import asksaveasfilename# 弹出文件选择对话框选择保存文件
write_file_name = asksaveasfilename()
if write_file_name != "":print("you can write data to " + write_file_name)with open(write_file_name, "w", encoding="utf-8") as file:file.write("你好中国")
else:print("你未选择一个文件")

2.选择或者输入对话框

用途：

• 显示特定消息警告

• 提示用户输入数字和字符串

import tkinter.messagebox
import tkinter.simpledialog
import tkinter.colorchooser# 显示特定信息或警告
tkinter.messagebox.showinfo("对话框名字，它在对话框左上角", "对话框中间的内容")
tkinter.messagebox.showwarning("showwarning", "This is a warning")
tkinter.messagebox.showerror("showerror", "This is an error")# 提示用户进行选择，并获取值
isYes = tkinter.messagebox.askyesno("askyesno", "Contiue ?")
print(isYes)  # True 或者 False
isOk = tkinter.messagebox.askokcancel("askokcancel", "OK ?")
print(isOk)   # True 或者 False
isYesNoCancel = tkinter.messagebox.askyesnocancel("askyesnocancel", "Yes, No, Cancel ?")
print(isYesNoCancel)  # True 或者 False 或者 None# 提示用户进行输入，并获取值
name = tkinter.simpledialog.askstring("askstring", "Enter your name")
print(name)   # OK返回输入的内容，取消返回None,
age = tkinter.simpledialog.askinteger("askinteger", "Enter your age")
print(age)    # OK返回输入的内容，输入非整数会报错，会让其重新输入，取消返回None,
weight = tkinter.simpledialog.askfloat("askfloat", "Enter your weight")
print(weight)
