sigh ... when will people learn ... one-liners are not good. Especially when they lead to bugs. For example #4 in the list. If you that didn't jump out to you as a bug. You are a fucking idiot and shouldn't be writing production code.
- hythloday 14y agoFor reference, a correct #4 would read: with open("one_liners.py") as f: print f.readlines() In CPython, a file handle is closed immediately the file goes out of scope, because it's reference-counted. In Jython (and I believe IronPython too), with lazier garbage collection, the filehandle would stay open until it was gc'd. I have no idea about PyPy's behaviour.
