Hello all,
I have been making some big multiplots lately and found a nice little
way of writing out 30 plots as follows, this part works great and leads up
to my question, here I have 30 sets defined by the set=(), in this case I
get a nice arrangement of 30 plots for V(GSR) and Log(g) (2

You should not override the builtin set() type [1] as you've done here by
assigning
Hi everyone,
Is there any decent barcode decoder software which one could use to read
image barcodes and return a result to a calling function/ app? I wish to
implement a Python server backend which would import and use such a module
(if it were that, for instance).
Thanks.

HI,
Would anyone have tips on how to generate random 4-digit alphanumeric codes
in python? Also, how does one calculate the number of possible combinations?
Thanks in advance.

Python's, random module is your
First of all, determine your alphabet (the pool of characters you'll derive
your 4-character code from):
- For example, using an English alphabet with both lowercase and uppercase
letters and digits 0-9 makes for 62 characters (26 + 26 + 10).
Then, ask if you want to allow a character to repeat
Correcting what was said below.
- If not, then it's a little more complicated, calculate (length) *
(length-1) * (length-2) * (length-3), or in other words the factorial of
length divided by the factorial of (length - 4). In my example, 62! /
(62-4)! = 13,388,280

I'm a bit confused about extracting data using re.search or re.findall.
Say I have the following code: tuples =
re.findall(r'blahblah(\d+)yattayattayatta(\w+)moreblahblahblah(\w+)over',
text)
So I'm looking for that string in 'text', and I intend to extract the parts
which have parentheses

If you want to know *how* Python does it you will have to read the
module code (probably in C so download
Dear Don,
Thanks for the comment, the set type is no problem for me, this is just
a variable that I call set... and it works great for my purposes, I do
suspect it is something in the way that matplotlib/pyplot deals with
histograms, but I have not so far been able to find the right syntax.
Yay Python:
The solution was a syntax one, if anyone else ever feels like massively
multi-plotting histograms, here is the working code:
#--
fig, axes = plt.subplots(nrows=5, ncols=6, figsize=(12,6))
index=0
for b in axes:
for ax in b:
15 matches
