New submission from WIl Hall <w...@wilhall.com>: When creating lambda functions in a loop, variables involved in the lambda statements appear to not resolve until the loop finishes. This results in all of the defined lambda functions using the same variable to resolve to the last value of that variable.
For example, in my test program attached, I loop through a list of words: ["one", "two", "three", "four"] and create a function for each word, I.e: lambda: print_word(word). This results in every function having the word "four" as their argument. This doesn't seem like intended behavior. Im my example program attached, I demonstrate both the intended and not intended behavior - creating the lambda functions in another function, versus creating them in a loop. ---------- components: Interpreter Core files: lambda_tests.py messages: 150107 nosy: wilhall priority: normal severity: normal status: open title: Creating lambda functions in a loop has unexpected results when resolving variables used as arguments type: behavior versions: Python 2.6, Python 2.7 Added file: http://bugs.python.org/file24078/lambda_tests.py _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue13652> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
