But I run pycco maths/add.py，it's ok. so What is the reason for this?

It looks like you’re using Unix glob syntax with Windows? I don’t have windows, so I’m not sure if that’s expected to work.

[jshipley]

Windows does not do shell expansion in the same way that sh does, it expects the program to do the shell expansion.

The best way to handle this input would be to use glob (either from pathlib.Path or glob) to expand the sources before using them.

As a workaround (in powershell), you could run this to expand the glob before passing it to pycco.

pycco -p (maths/*.py | Resolve-Path -Relative)

Or if you wanted to do something like myproject/**/*.py, you could do it like this:

pycco -p (Get-ChildItem -Recurse -Path myproject -File -Filter *.py | Resolve-Path -Relative)
