Passing all pandas DataFrame columns to function as separate parameters
by zljubisic＠gmail.com April 27, 2018

April 27, 2018

Hi, I have pandas DataFrame with several columns. I have to pass all columns as separate parameter to a function. Something like this if I have 4 columns. f, p = stats.f_oneway(df_piv.iloc[:, 0], df_piv.iloc[:, 1], df_piv.iloc[:, 2], df_piv.iloc[:, 3]) As number of columns varies, how to do it in the most efficient way? Regards.

Question about Decimal and rounding
by Frank Millman April 27, 2018

April 27, 2018

Hi all I have an object which represents a Decimal type. It can receive input from various sources. It has to round the value to a particular scale factor before storing it. The scale factor can vary, so it has to be looked up every time, which is a slight overhead. I thought I could speed it up a bit by checking first to see if the value has any decimal places. If not, I can skip the scaling routine. This is how I do it - s = str(value) if '.' in s: int_portion, dec_portion = s.split('.') is_integer = (int(int_portion) == value) else: is_integer = True It assumes that the value is in the form iii.ddd or just iii. Today I found the following value - -1.4210854715202004e-14 which does not match my assumption. It happens to work, but I don't understand enough about the notation to know if this is reliable, or if there are any corner cases where my test would fail. I suspect that my test is a case of premature optimisation, and that I might as well just scale the value every time. Still, I would be interested to know if this could be a problem, or if there is a better way to do what I want. Thinking aloud, maybe this is a better test - is_integer = (value == value.quantize(0)) Thanks Frank Millman

setuptools setup.py commands are unintuitive and undiscoverable (--help-commands should replace --help)
by jimbo1qaz April 27, 2018

April 27, 2018

Frequently I have encountered projects packaged using setuptools, with a setup.py. To find out how to install it, I usually turned to Stack Overflow (https://stackoverflow.com/a/1472014) which doesn't explain what options exist or do. Surprisingly, neither "setup.py" nor "setup.py --help" doesn't provide a list of options either, instead telling you how to show various metadata options which are not useful to end users of the software project, trying to build/install it. Instead, to show a list of useful actions a user can perform, you need to use "setup.py --help-commands", which I only discovered several years after starting to use Python. Why isn't this command enabled by default (called without arguments, or with --help). https://imgur.com/a/HF4Iw6D

detect laptop open/close from within Python?
by Skip Montanaro April 26, 2018

April 26, 2018

I'm going through a bout of RSI problems with my wrists, so klst night I refreshed an old typing watcher program I wrote a couple decades ago (there's a comment about Python 1.4 in the code!): https://github.com/smontanaro/python-bits/blob/master/watch.py It's far from perfect and I'm sure miles behind more modern stuff, but it does the trick for me. I noticed a feww minutes ago that when I opened my laptop it immediately locked the screen. It would be nice to get notified of open/close events on the laptop. Any idea if there is a signal I can catch (Ubuntu 17.10) or a Tk event I can respond to? Thx, Skip

by Cecil Westerhof April 26, 2018

April 26, 2018

After I updated pip2/3 to 10 from 9 I sometimes get: Cache entry deserialization failed, entry ignored For example when I execute: pip3 list --outdated But not always. What could be happening here? And how would I solve this? -- Cecil Westerhof Senior Software Engineer LinkedIn: http://www.linkedin.com/in/cecilwesterhof
