It's not a bug. strip() does not work like you think. Please read the
documentation

New submission from Akilesh K :
When the argument to lstrip / strip has a number and it matches the string it
begins to act different.
>>> text = "apiv1appliance"
>>> text.strip("apiv1")
'liance'
>>> text.strip("apiv2")
'1appliance'
>>> text.strip("a")
'piv1appliance'
>>> text.strip("ap")
