Python text operations module
Project description
When you access an object with chained attributes
info = obj.a.b.c.d or 'Unknown'
Usually, it will failed when one intermediate attribute return ‘None‘
if obj.a returns None obj.a.b.c.d will fail with that exception : AttributeError: 'NoneType' object has no attribute 'xxx'
To avoid that, instead of returning a ‘None‘ value, one should return ‘NoAttr‘, by this way, even next chained attribute will return ‘NoAttr‘
if obj.a returns NoAttr obj.a.b.c.d will not fail and will return NoAttr
‘NoAttr‘ can be seen as False, ‘’, [], {} depending on the context, so
if obj.a returns NoAttr obj.a.b.c.d or 'Unknown' will return 'Unknown'
