How to deal with multiple dots in a file name with Python pathlib?

Question

I am having an issue with pathlib when I try to construct a file path that has a "." in its name, the pathlib module ignores it.

Here are example lines (I tried multiple versions, all resulted the same issue)

The issue is that the original file name will be coming from another application, so it is not like I can edit the name myself. I also do not want to do string replacement work arounds, if possible.

path=r"c:\temp"

1

p=Path(path).joinpath("myfile.001").with_suffix(".bat")

2

p=Path(path, "myfile.001").with_suffix(".bat")

3

p=Path(path).with_name("myfile.001").with_suffix(".bat")

All these lines will yield to

WindowsPath('C:/temp/myfile.bat')

So how do I make pathlib.Path to construct this full path properly. The final path has to be

WindowsPath('C:/temp/myfile.001.bat')

Not

WindowsPath('C:/temp/myfile.bat')

Naturally I am looking for a way to do it through pathlib itself, otherwise I can just use os.

thanks

You are telling pathlib to replace the suffix .001 with the suffix .bat. pathlib complies.

Tell pathlib to add .bat to the existing suffix.

p = Path(path, 'myfile.001')
p = p.with_suffix(p.suffix+'.001')
