Hi,
Need some help,
in the Python, I have a array of string
var_array=["Opt1=DG","Opt1=DG2"]
I need to call c library and pass var_array as parameter
In the argtypes, how do I set up ctypes.POINTER(???) for var_array?

A ctypes data type has an in_dll() met
On a Windows 10 platform (python 3.8.9 and 3.9.5), how do I use ctypes to
access an array of uint32_t's exported from a DLL?
The array (after various #define's are resolved) is defined as:

Every array in numpy has a number of dimensions,
"np.array" is a function that can create an array numpy given a list.
when you write

Hello Peter,
Many thanks for your suggestion.
Now I am using Pandas &
I already did that but now I need to make a multi-dimensional array for reading
all variables (5 in this case) at one x-axis, so I can perform multiple
regression analysis.
I am not getting how to bring all variable

Hi, All,
I have 6 variables in CSV file. One is rainfall (dependent, at y-axis) and
others are predictors (at x). I want to do multiple regression and create a
correlation matrix between rainfall (y) and predictors (x; n1=5). Thus I want
to read rainfall as a separate variable and others in sep
Thanks very much, it was pretty easy and now it works :)

Hi again,
I am trying to subtract the minimum value from all numbers (in one array). I am
using this:
(array[:,1] -= np.min(array[:,1]) but I alsways have syntaxerror:invalid

Thanks a lot, it helped me.
I have new question..maybe very easy but I am trying to search on web and I
have no clue.
I have array(table) with 3 rows - x, y, y. I would like to plot graph with
double y axis from that table. Should I use twinxs? or does exist easier way?
Thanks!

Thank you for the reply.
I tried that, I am trying to do this.
The context is I am trying to find mapk ( k = 3 ) for this list.
A, B , C, D and E are product names.
If I am trying manually I will do something like this.
TRUTH = [[A], [B,C], [A], [D,E]]
and if my prediction is :
PRED=[[B,A, D],
You can do this with pandas:
import pandas as pd
from io import StringIO
io = StringIO('''\
idABCDE
10010000
10101100
10210
I have a dataset in the below format.
id A B C D E
100 1 0 0 0 0
101 0 1 1 0 0
102 1 0 0 0 0
103 0 0 0 1 1
I would like to convert this into below:
100, A

on 3.5 on Windows and I get an exception:
SystemError: new style getargs format but argument is not a tuple
From what I've been able to find out, the argument of 'putdata' should
be a list (sequence) of tuples.
A quicker way is to create a new image from the array:
im = Image.fromarray(arr)
