Python error: string index out of range - python

I try to update a game of n in a row. But when I try to update the array matrix i get the "string out of range error.
I made a while statement with ind < len(board_height).
What am I doing wrong here?

Getting the subheaders in openpyxl

I'm currently using openpyxl to use an excel file that has mul-indices (2 Levels of headers) and i'm trying to do the operations depending on the subheaders a header has.
I have some exp. doing this in pandas but for this Project i have to use openpyxl which i barly made any use of before.
Only thing i could think off is the manual way:
iterating over the rows
saving the first row as header and 2nd row as subheader
do some cleaning.
manually save the headers with their subheaders in dics. then filleing in the values by iterating over all the cols
my code is as follows:
#reading the excel file
path = r'path to file'
wb = load_workbook(path) #loading the excel table
ws = wb.active #grab the active worksheet
#Setting the doc Header
for h in ws.iter_rows(max_row = 1, values_only = True): #getting the first row (Headers) in the table
header = list(h)
for sh in ws.iter_rows(min_row = 1 ,max_row = 2, values_only = True):
sub_header = list(sh)
#removing all of the none Values
header = list(filter(None, header))
sub_header = list(filter(None, sub_header))
print(header)
print(sub_header)
#creating a list of all the Columns in the excel file
col_list = []
for col in ws.iter_cols(min_row=3,min_col = 1): #Iteration over every single row starting from the third row since first two are the headers
col = [cell.value for cell in col] #Creating a list from each row
col = list(filter(None, col)) #removing the none values from each row
col_list.append(col) #creating a list of all rows (starting from the 3d one)
#print (col_list)
But i'm sure there must be a better way that i wasnt able to find in the docs or by checking this website.
Thanks in advance!
My goal in the end is to automate this part of my code by iterating over the header and use the subheaders of that head and their values each time
code:
#bulding the templates using yattag "yattag.org"
doc , tag , text = Doc().tagtext()
#building the tags of the xml file

Unless Pandas is completely off the table I think you might be able to do something pandas and openpyxl. The documentation mentions reading data from openpyxl into a pandas dataframe: Working with Pandas and Numpy.
Could you use:
data = ws.values
df = DataFrame(data[2:,:], index=data[0], columns=data[1])
There may be some filtering necessary with regards to the None values.

How to get new line

How can I print a new line on the output file? When I try to add the new line with "/n" it just prints /n
This is what I have so far.
``
inputFile = open("demofile1.txt", "r")
outFile = open("Ji
string = line.split(',')
go =(string)[3::]
bo = [float(i) for i in go]
total = sum(bo)
pine = ("%8.2f"%total)
name = string[2] + "," + " " + string[1]
kale = (string[0] + " " + name + " " + "/n")
se)
Current Result
8
53 Baul
A999999

You need to use \n, not /n. So this line:
kale = (string[0] + " " + name + " " + "/n")
Should be:
kale = (string[0] + " " + name + " " + "\n")
Also, please do consider using a str formatter, so all these lines:
go =(string)[3::]
bo = [float(i) for i in go]
total = sum(bo)
pine = ("%8.2f"%total)
name = string[2] + "," + " " + string[1]
kale = (string[0] + " " + name + " " + "/n")
str1 = ''.join(kale)
str2 = ''.join(pine)
outFile.write(str1 + " " + str2 + " ")
Will become:
outFile.write("{} {} {:8.2f}\n".format(string[0], string[2] + ", " + string[1], sum(bo))

Python plot Legend Key Format

I am trying to plot a set of data in python. I'm using matplotlib.pyplot library to do this.
I got everything working, but I have this one issue where the last key in the legend comes out with a weird format than the others. I tried to do different settings to get this fixed with no luck so far... Can anyone help me fix that CH4 (A) to show in the same format as the other keys?
The format looks much like this in the plot (I cannot post picture until I get 10 reputations
CH1 (A)
CH2 (A)
CH3 (A)
CH4
(A
)
Here is my code to set up legend.
legends = data[16]
legends = legends.split(",")
if numChannels == 1:
plt.plot(raw[:,0],raw[:,1], label=legends[1] + " (" + units[1] + ")")
elif numChannels == 2:
plt.plot(raw[:,0],raw[:,1], label=legends[1] + " (" + units[1] + ")")
plt.plot(raw[:,0],raw[:,2], label=legends[2] + " (" + units[2] + ")")
elif numChannels == 3:
plt.plot(raw[:,0],raw[:,1], label=legends[1] + " (" + units[1] + ")")
plt.plot(raw[:,0],raw[:,2], label=legends[2] + " (" + units[2] + ")")
plt.plot(raw[:,0],raw[:,3], label=legends[3] + " (" + units[3] + ")")
elif numChannels == 4:
plt.plot(raw[:,0],raw[:,1], label=legends[1] + " (" + units[1] + ")")
plt.plot(raw[:,0],raw[:,2], label=legends[2] + " (" + units[2] + ")")
plt.plot(raw[:,0],raw[:,3], label=legends[3] + " (" + units[3] + ")")
plt.plot(raw[:,0],raw[:,4], label=legends[4] + " (" + units[4] + ")")
plt.legend(loc=0)
plt.xlabel(legends[0])
plt.ylabel("Data")
plt.title(filestr)
plt.show()
legends is data I am reading in from a .csv file. I'm not really sure why this happens. This only happens to the last legend. E.g. if I have 4 data set and plot 3, they come out fine, but if I plot all 4 or only have 1 data set and plot, the key is formatted differently as shown above.

I think you units[4] data may contain some newline characters (\n) which are causing the strange legend format. If you setup the legend and units strings manually, you get what looks like correct formatting,
import numpy as np
import matplotlib.pyplot as plt
raw = np.random.random((20,5))
legends = [" ", "CH1 ","CH2 ","CH3 ","CH4 "]
units = [" ", "A","A","A","A"]
numChannels = 4
if numChannels == 1:
plt.plot(raw[:,0],raw[:,1], label=legends[1] + " (" + units[1] + ")")
elif numChannels == 2:
plt.plot(raw[:,0],raw[:,1], label=legends[1] + " (" + units[1] + ")")
plt.plot(raw[:,0],raw[:,2], label=legends[2] + " (" + units[2] + ")")
elif numChannels == 3:
plt.plot(raw[:,0],raw[:,1], label=legends[1] + " (" + units[1] + ")")
plt.plot(raw[:,0],raw[:,2], label=legends[2] + " (" + units[2] + ")")
plt.plot(raw[:,0],raw[:,3], label=legends[3] + " (" + units[3] + ")")
elif numChannels == 4:
plt.plot(raw[:,0],raw[:,1], label=legends[1] + " (" + units[1] + ")")
plt.plot(raw[:,0],raw[:,2], label=legends[2] + " (" + units[2] + ")")
plt.plot(raw[:,0],raw[:,3], label=legends[3] + " (" + units[3] + ")")
plt.plot(raw[:,0],raw[:,4], label=legends[4] + " (" + units[4] + ")")
plt.legend(loc=0)
plt.xlabel(legends[0])
plt.ylabel("Data")
plt.show()
which gives,

Get field name from an object retrieved by orm query

I have a small Django app, and when I query my DB with django orm I get my objects list.
What I want is the name of the db column where the query has matched.
Is possible?
Thanks in advance!
results = Verbs.objects.filter(
Q(fps__icontains = " " + word_name + " ") | Q(fps__endswith = " " + word_name) | Q(fps__startswith = word_name + " ") |
Q(sps__icontains = " " + word_name + " ") | Q(sps__endswith = " " + word_name) | Q(sps__startswith = word_name + " ") |
Q(tps__icontains = " " + word_name + " ") | Q(tps__endswith = " " + word_name) | Q(tps__startswith = word_name + " ") |
Q(fpp__icontains = " " + word_name + " ") | Q(fpp__endswith = " " + word_name) | Q(fpp__startswith = word_name + " ") |
Q(spp__icontains = " " + word_name + " ") | Q(spp__endswith = " " + word_name) | Q(spp__startswith = word_name + " ") |
Q(tpp__icontains = " " + word_name + " ") | Q(tpp__endswith = " " + word_name) | Q(tpp__startswith = word_name + " ")
).all()
What I want is the name of field where the query as matched. For example: fps or fpp ...

I think this is what you want--for each returned row it will print the matched fields, indented:
fields = ('fps', 'sps', 'tps', 'fpp', 'spp', 'tpp')
for r in results.values():
print 'Row with id=%s:' % r['id']
for f in fields:
if word_name in str(r[f]):
print ' Field %s matches' % f
Edited to account for non-string values and to look only at the desired fields.
