Anyone else getting this error? I tried on Debian 9 and MacOS 10.14.6 after installing via pip.

  import reloading
  Traceback (most recent call last):
    File "<input>", line 1, in <module>
      import reloading

    exc = exc.replace('File "<string>"', f'File "{fpath}"')
                                                         ^
  SyntaxError: invalid syntax

It only works with Python 3. Thanks for reminding me that I should add a note to the Readme.

It does work in Python 2 with the following patch:

    diff --git a/reloading/reloading.py b/reloading/reloading.py

Brilliant, thank you. I'll patch that.

That's an f-string, so it only works with Python 3.7 and later

f-strings were introduced in Python 3.6, fyi:
