Error when using the example code

[git-jamesfrench]

Hello, i have installed sunzip on my windows computer using "pip install sunzip" and i got an error when using this example code :

import sunzip

f = sunzip.Sunzip("archive.zip")

f.extract()

the error

Traceback (most recent call last):
  File "c:\Users\*****\Desktop\sunzip\sunzip.py", line 1, in <module>
    import sunzip
  File "c:\Users\*****\Desktop\sunzip\sunzip.py", line 3, in <module>
    f = sunzip.Sunzip("archive.zip")
        ^^^^^^^^^^^^^
AttributeError: partially initialized module 'sunzip' has no attribute 'Sunzip' (most likely due to a circular import). Did you mean: 'sunzip'?

Thanks !
