Lots of ideas. However, if you want practical help, edit your question to show ALL of your code. Also tell us what is the “it” that shows memory used, what it shows when you load a file with zero entries, and what platform you are on, and what version of Python. You say that “the … Read more
The second option is more Pythonic for two reasons: It is one operator, translating to one bytecode operand. The other line is really not (4 in a); two operators. As it happens, Python optimizes the latter case and translates not (x in y) into x not in y anyway, but that is an implementation detail … Read more
From the documentation of raw_input: The function then reads a line from input, converts it to a string (stripping a trailing newline), and returns that. So what happens is that you try to multiply a string with a float, something like y=”3″ * x – 0.5 * “3” *x**2, which is not defined. The easiest … Read more
Python supports arbitrary precision integers, meaning you’re able to represent larger numbers than a normal 32 or 64 bit integer type. The L tells you when a literal is of this type and not a regular integer. Note, that L only shows up in the interpreter output, it’s just signifying the type. If you print … Read more
None is being returned >>> print min([None, 1,2]) None >>> None < 1 True If you want to return 1 you have to filter the None away: >>> L = [None, 1, 2] >>> min(x for x in L if x is not None) 1
Just call the .time() method of the datetime objects to get their hours, minutes, seconds and microseconds. dt = datetime.strptime(start,”%H:%M:%S”).time()
For (at least) Python 3.7 According to the docs: bytes objects are immutable sequences of single bytes bytearray objects are a mutable counterpart to bytes objects. And that’s pretty much it as far as bytes vs bytearray. In fact, they’re fairly interchangeable and designed to flexible enough to be mixed in operations without throwing errors. … Read more
You want to use chardet, an encoding detector
You should use sys.getdefaultencoding()
I think it’s as simple as not converting to ASCII first. >>> print u’exámple’.upper() EXÁMPLE
