操作 os.path

Question

我试图检查某个文件是否存在，但是，存在的文件保存为 .png。 有没有办法使用 os.path 来查看没有 .png 部分的文件是否存在？ 例如我想看看example.png是否存在所以我输入“example”而不是“example.png”

这是我到目前为止所拥有的：

import os

filepath = str(input("If you want to make a new file, type None otherwise enter the file that it is being written to: "))
        while os.path.isfile(filepath) is False:
            if filepath == "None":
                filepath = functnone()
                break
            print("That filepath doesn't exist")
            filepath = str(input("If you want to make a new file, type None otherwise enter the file that it is being written to: "))

如果文件是 .png，这显然有效，但是我该如何更改它，所以我需要做的就是检查没有 .png 的第一位？

Answer 1

您只需要使用 '.png' 将您的输入进行字符串连接

这看起来像：

import os

filepath = str(input("If you want to make a new file, type None otherwise enter the file that it is being written to: "))+'.png'
        while os.path.isfile(filepath) is False:
            if filepath == "None":
                filepath = functnone()
                break
            print("That filepath doesn't exist")
            filepath = str(input("If you want to make a new file, type None otherwise enter the file that it is being written to: "))+'.png'
