Yeah, I caught that after I tried running the script in a dedicated console in Spyder, and my logging worked as expected.

Mysterious Logging Handlers
by Josh English Sept. 12, 2016

Sept. 12, 2016

I have a Python script that imports a utility script. Both scripts use logging, but the logs don't work as advertised. I'm getting logging output from the utility script but none from the main file. Worse, the format of the utility script's logs don't match anything I define. The utility script is called xlreader.py. It has the following lines: -- begin snippet -- import logging XLOGGER = logging.getLogger('XLREADER') -- end snippet -- And it calls XLOGGER.debug(), XLOGGER.error() and XLOGGER.info() but it never defines a handler. The main script imports xlreader but does not reference XLOGGER. It defines its own logger: -- begin snippet -- import logging import xlreader LOG = logging.getLogger('SHIPPING') FORMAT = '%(asctime)-15s %(name)s %(level)-8s %(message)s' logging.basicConfig(format=FORMAT,level=logging.DEBUG) handler = logging.StreamHandler() formatter = logging.Formatter(FORMAT) handler.setFormatter(formatter) LOG.addHandler(handler) -- end snippet -- I added the logging.basicConfig line but it didn't have any effect. I created the second handler separately. When I run the scriptI get logging information from only xlreader, not from the main script: DEBUG:XLREADER:Creating Excel Reader This format isn't defined anywhere. T Even more mysterious, after I run the file (in an IDE so I have a REPL afterwards), I have: >>> XLOGGER >>> <logging.Logger at 0x981a208> >>> XLOGGER.handlers >>> [] >>> XLOGGER.debug('test') >>> DEBUG:XLREADER:test >>> LOG.handlers >>> [<logging.StreamHandler at 0x97e3c88>, <logging.StreamHandler at 0xb2954e0>] >>> [h.formatter._fmt for h in LOG.handlers] >>> ['%(asctime)-15s %(name)s %(level)-8s %(message)s', '%(asctime)-15s %(name)s %(level)-8s %(message)s'] How can I track where this formatting is coming from?

There is some merit in this. For instance, Python 2 had a lower-level consistency in the division operator than Python 3 has. According to Py2, integers and floats are fundamentally different beasts, and when you divide an int by an int, you get an int, not a float. Py3 says "well, you probably REALLY meant to divide a number by a number", so it gives you a float back, unless you explicitly ask for floor division. Py2 is more consistent on a lower level of abstraction. Py3 is more consistent on a higher level of abstraction (modulo the oddities at extremely large numbers). Both have merit, but in a high level language, the Py3 way is usually [1] better. But the consistency of call-by-object-reference is at the same high level as the consistency of call-by-value or call-by-name. I can explain Python's assignment model to someone fairly easily, using pencil and paper, without any reference to "low level" or "high level" concepts. And Python is extremely internally consistent; *every* assignment behaves the exact same way. How does "import x" compare with "from x import y"? Easy: the former is "x = some_module_object", and the latter is "y = some_module_object.y", and either way, it's regular assignment. How does parameter passing work? You take the value of the argument as evaluated in the caller, and assign it to the parameter in the function. What about default arguments? They're evaluated when the function's defined, and assigned to the parameter when it's called. Function definition itself is the same thing - it's assigning a function object to a name. Python handles every one of them the same way. I don't care one iota about how voltages inside a CPU operate. I don't generally even care about machine code - let other people worry about that, people more expert than I am. Discussions about how the core dev and the novice see Python's consistencies are nothing to do with those levels. To go back to your original point, that a newbie is better at recognizing inconsistencies... maybe, in a sense, but they also get a lot of false positives. Ultimately, "consistent" means that there's a single pattern that explains everything; if you're unaware of that pattern, you won't know that it's consistent. ChrisA [1] Even in Python, there are places where low-level consistency is better, because Python is a glue language. But in general, it's better for Python to be consistent with humans than with C APIs.

Calling SM(...,trg[1:],src[1:]) gives plausible result. See also the result of .get_matching_blocks() on your strings (it returns no matching blocks). It is all due to the "Autojunk" heuristics (see difflib's doc for details), which considers the first characters as junk. Call SM(...,autojunk=False).
