StopIteration exception ...

[David Sierro]

Dear colleagues,

i am using python3.7 and i have tried many web.py different versions (pip install web.py==0.40.dev0, git+https://github.com/webpy/webpy#egg=web.py, ...) so far, however, i am always getting the StopIteration error for the following code

urls = (

    '/x1/(.*)', 'x1',

    '/x2/(.*)', 'x2',

    '/x3/(.*)', 'x3'

)

app = web.application(urls, globals())

ERROR 

app = web.application(urls, globals())

  File "C:\Users\D056772\AppData\Local\Programs\Python\Python37-32\web\application.py", line 62, in __init__

    self.init_mapping(mapping)

  File "C:\Users\D056772\AppData\Local\Programs\Python\Python37-32\web\application.py", line 130, in init_mapping

    self.mapping = list(utils.group(mapping, 2))

  File "C:\Users\D056772\AppData\Local\Programs\Python\Python37-32\web\utils.py", line 531, in group

    x = list(take(seq, size))

RuntimeError: generator raised StopIteration

The same code works in a Mac with Python2.7

Could you please support on this? Thanks in advance.

Kind regards,

David
