The reason why python has quirks like 'sqrt' being faster than 'numpy.sqrt' is because python variables are untyped. That is the chief reason for so much trouble with python performance. Debugging is a nightmare for the same reason. The lack of multi-line comment syntax (found in most other languages ,e.g. /*...*/,) is another irksome quality. However, python's superb libraries make it the only real choice for some applications. Just my opinion based on much experience.,(reply>), Triple quotes are for multiline Strings. They are not ignored by the parser and are garbage collected if not assigned to a variable. Another hack is their use as a comment to get around python language deficiencies.,(reply>), Triple quotes is multi-line comment syntax in Python….,(reply>), Tell Thomas I referred you to him.....
