操纵os.path

Question

我试图检查某个文件是否存在，但是，存在的文件被保存为.png。是否有一种方法可以使用os.path来查看没有.png部件的文件是否存在？例如，我想看看example.png是否存在，所以我输入“示例”而不是"example.png“

以下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，这显然是有效的，但是我如何更改它，所以我所需要做的就是检查不带.png的第一个位？

您只需将输入与“.png”进行字符串连接即可

这看起来应该是：

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'
