We Keep Coding

When trying to append a string to a list I get an error

I am coding a script in python that automatically writes a file which you can use in the DecentSampler plugin, I am running into an error right now which I am not understanding.
noteGroups = []
firstGroup = True
print(noteGroups)
for file in files: #Writes all the files in the pack.
rfeS = ""
strFile = str(file)
rfe = strFile.split(".", 1)
rfe.pop(-1)
for rfeX in rfe:
rfeS += rfeX
filesSplit = rfeS.split("_", 1)
note = filesSplit[0]
rr = filesSplit[1]
noteList = note.split("delimiter")
print(noteList)
if note not in noteGroups:
noteGroups = noteGroups.append(note)
print(noteGroups)
if firstGroup:
dsp.write("\n </group>")
firstGroup = False
dsp.write("\n <group>")
dsp.write("\n <sample path=\"" + dir + "/" + file + "\" volume=\"5dB\" rootNote=\"" + note + "\" loNote=\"" + note + "\" hiNote=\"" + note + "\" seqPosition=\"" + rr + "\" />")
else:
print(noteGroups)
dsp.write("\n <sample path=\"" + dir + "/" + file + "\" volume=\"5dB\" rootNote=\"" + note + "\" loNote=\"" + note + "\" hiNote=\"" + note + "\" seqPosition=\"" + rr + "\" />")
print(noteGroups)
I am getting the error
File "D:\Python\GUI-test\dshgui.py", line 109, in dspWrite
if note not in noteGroups:
TypeError: argument of type 'NoneType' is not iterable
But if I try this:
noteGroups = ["test", "test"]
note = "A2"
noteGroups.append(note)
print(noteGroups)
It does function properly...
Does anyone know why? And how I can fix it?

The problem is this line:
noteGroups = noteGroups.append(note)
append modifies the list in-place and then it returns None. Don't assign that None value back to the name of the original list. Just do:
noteGroups.append(note)

PDF template not merging data properly with pdftk

I'm editing a PDF template with using pdftk
command = ("pdftk " + '"' +
template + '"' +
" fill_form " + '"' +
pathUser + user['mail'] + ".xfdf" + '"' +
" output " + '"' +
pathUser + user['mail'] + ".pdf" + '"' +
" need_appearances")
command = command.replace('/', '\\')
os.system(command)
First I'm writing my data in a .xfdf file
for key, value in user.items():
print(key, value)
fields.append(u"""<field name="%s"><value>%s</value></field>""" % (key, value))
tpl = u"""<?xml version="1.0" encoding="UTF-8"?>
<xfdf xmlns="http://ns.adobe.com/xfdf/" xml:space="preserve">
<fields>
%s
</fields>
</xfdf>""" % "\n".join(fields)
f = open(pathUser + user['mail'] + '.xfdf', 'wb')
f.write(tpl.encode("utf-8"))
f.close()
I fetch the template and as shown above, write the data from the xfdf to pdf but for some reason, only the ime gets written.
Templates get fetched using some basic conditional logic as shown below:
for item in user['predavanja']:
user[acthead + str(actn)] = item
actn += 1
for item in user['radionice']:
user[acthead + str(actn)] = item
actn += 1
for item in user['izlet']:
user[acthead + str(actn)] = item
actn += 1
print(actn)
templates = {}
templates['0'] = "Template/2019/certificate_2019.pdf"
templates['5'] = "Template/2019/certificate_2019_5.pdf"
templates['10'] = "Template/2019/certificate_2019_10.pdf"
templates['15'] = "Template/2019/certificate_2019_15.pdf"
templates['20'] = "Template/2019/certificate_2019_20.pdf"
templates['25'] = "Template/2019/certificate_2019_25.pdf"
templates['30'] = "Template/2019/certificate_2019_30.pdf"
templates['35'] = "Template/2019/certificate_2019_35.pdf"
templates['40'] = "Template/2019/certificate_2019_40.pdf"
templates['45'] = "Template/2019/certificate_2019_45.pdf"
templates['50'] = "Template/2019/certificate_2019_50.pdf"
I'm writing this data
user['id'] = data['recommendations'][0]['role_in_team']['user']['id']
user['ime'] = data['recommendations'][0]['role_in_team']['user']['first_name']
user['prezime'] = data['recommendations'][0]['role_in_team']['user']['last_name']
user['tim'] = data['recommendations'][0]['role_in_team']['team']['short_name']
user['mail'] = data['recommendations'][0]['role_in_team']['user']['estudent_email']
user['puno_ime'] = (data['recommendations'][0]['role_in_team']['user']['first_name'] + ' ' +
data['recommendations'][0]['role_in_team']['user']['last_name'])
user['predavanja'] = predavanja
user['radionice'] = radionice
user['izlet'] = izlet
One note. predavanja, radionice and izlet are lists.
I've tried printing tpl which shows all the data being properly added to the scheme.

Turns out the issue was the naming of the variables since they didn't match the field names in the acroform PDF. So the solution was to rename the variables in the code to match the field names.

Why does my Python XML parser break after the first file?

I am working on a Python (3) XML parser that should extract the text content of specific nodes from every xml file within a folder. Then, the script should write the collected data into a tab-separated text file. So far, all the functions seem to be working. The script returns all the information that I want from the first file, but it always breaks, I believe, when it starts to parse the second file.
When it breaks, it returns "TypeError: 'str' object is not callable." I've checked the second file and found that the functions work just as well on that as the first file when I remove the first file from the folder. I'm very new to Python/XML. Any advice, help, or useful links would be greatly appreciated. Thanks!

You are overwriting your function calls with the values they returned. changing the function names should fix it.

Parsing dynamic arabic character xml in python

This is the code. However, this code can only parse 4 characters of Arabian only. I want it to parse dynamically. So, the number of characters does not matter. Therefore, it can parse 1 character, 2 character or more based on the number of existing characters.
import xml.etree.ElementTree as ET
import os, glob
import csv
from time import time
#read xml path
xml_path = glob.glob('D:\1. Thesis FINISH!!!\*.xml')
#create file declaration for saving the result
file = open("parsing.csv","w")
#file = open("./%s" % ('parsing.csv'), 'w')
#create variable of starting time
t0=time()
#create file header
file.write('wordImage_id'+'|'+'paw1'+'|'+'paw2'+'|' + 'paw3' + '|' + 'paw4' + '|'+'font_size'+'|'+'font_style'+

for doc in xml_path:
print 'Reading file - ', os.path.basename(doc)
tree = ET.parse(doc)
#tree = ET.parse('D:\1. Thesis FINISH!!!\Image_14_AdvertisingBold_13.xml')

#get wordimage id

How to encrypt a .bin file

I need to encrypt 3 .bin files which contain 2 keys for Diffie-Hellman. I have no clue how to do that, all I could think of was what I did in the following Python file. I have an example what the output should look like but my code doesn't seem to produce the right keys. The output file server.ini is used by a client to connect to a server.
import base64
fileList = [['game_key.bin', 'Game'], ['gate_key.bin', 'Gate'], ['auth_key.bin', 'Auth']]
iniList = []
for i in fileList:
file = open(i[0], 'rb')
n = list(file.read(64))
x = list(file.read(64))
file.close()
n.reverse()
x.reverse()
iniList.append(['Server.' + i[1] + '.N "' + base64.b64encode("".join(n)) + '"\n', 'Server.' + i[1] + '.X "' + base64.b64encode("".join(x)) + '"\n'])
iniList[0].append('\n')
#time for user Input
ip = '"' + raw_input('Hostname: ') + '"'
dispName = 'Server.DispName ' + '"' + raw_input('DispName: ') + '"' + '\n'
statusUrl = 'Server.Status ' + '"' + raw_input('Status URL: ') + '"' + '\n'
signupUrl = 'Server.Signup ' + '"' + raw_input('Signup URL: ') + '"' + '\n'
for l in range(1, 3):
iniList[l].append('Server.' + fileList[l][1] + '.Host ' + ip + '\n\n')
for l in [[dispName], [statusUrl], [signupUrl]]:
iniList.append(l)
outFile = open('server.ini', 'w')
for l in iniList:
for i in l:
outFile.write(i)
outFile.close()
The following was in my example file:
# Keys are Base64-encoded 512 bit RC4 keys, as generated by DirtSand's keygen
# command. Note that they MUST be quoted in the commands below, or the client
# won't parse them correctly!
I also tried it without inverting n and x
