Message331464
Code in question:
try:
# non-sequence items should not work with len()
# non-empty strings will fail this
if len(query) and not isinstance(query[0], tuple):
raise TypeError
# [. . .]
except TypeError:
ty, va, tb = sys.exc_info()
raise TypeError("not a valid non-string sequence "
"or mapping object").with_traceback(tb)
It is not redundant if you want a specific error message. I think that is the point of the code, to indicate the problem to the programmer. So the message is meant to be useful. I can think of three cases:
>>> urlencode(None) # Non-sequence
TypeError: not a valid non-string sequence or mapping object
>>> urlencode({'sized but not indexable'})
TypeError: not a valid non-string sequence or mapping object
>>> urlencode('item [0] not a tuple')
TypeError: not a valid non-string sequence or mapping object |
