Git commit f24284763f9b82366d8f86ee1f0f179333747d62 by Sven Brauch. Committed on 26/08/2012 at 21:46. Pushed by brauch into branch 'master'. Support iterating over lists of tuples while unpacking those. Code example: c = [(1, 2)] for a, b in c: print a, b # a, b are ints should fix M +48 -7 duchain/declarationbuilder.cpp M +24 -0 duchain/expressionvisitor.cpp M +4 -0 duchain/tests/pyduchaintest.cpp http://commits.kde.org/kdev-python/f24284763f9b82366d8f86ee1f0f179333747d62 |
When an iterable of tuples is used in a 'for' statement, and there are multiple variables in the 'target list' (thus unpacking the tuple), their types are incorrect. Unpacking a tuple in a normal assignment gives the correct types to the target variables: t = ("x", 0.5) a,b = t # 't' is tuple, 'a' is string, 'b' is float. But when iterating over a list of tuples, and unpacking directly in the 'for' statement, KDevelop seems not to handle the unpacking at all: seq = [("x", 0.5)] for a,b in seq: print a The type of 'a' shows as 'mixed' (unknown), and 'b' is typed as tuple<string,float>. Instead, 'a' should be 'string' and 'b' should be 'float'.
