self.zone.locations==None when parsing zones.mpk

I've finally made it through all of the linting errors when I converted the project from the archaic Python 2.7 code to Python 3.11. When I run python MapperGUI-3.pyw, the GUI loads but something is keeping the daoc game path from being loaded properly and stored, resulting in the error message "Game not found".
I've beat my ahead against the functions and variables and I am sure I'm missing something obvious, but for the life of me I cannot figure out where it is going wrong parsing the game directory of 'C:/Program Files (x86)/Electronic Arts/Dark Age of Camelot/'
For whatever reason, the program is stuck thinking self.zone.locations==None and I confirmed this by manually declaring the variable to a valid one and things worked fine.
MapperGUI/modules/zones.py is the module that loads the zones from the .mpk file dynamically. I verified mapper/all_locations.txt is being created properly when zones.py is parsed and called from the main program.
Did I miss something in zones.py? When I ran the 2 to 3 conversion on it, nothing was changed and I am not seeing any runtime errors.

Module urllib.request not getting data

I am trying to test this demo program from lynda using Python 3. I am using Pycharm as my IDE. I already added and installed the request package, but when I run the program, it runs cleanly and shows a message "Process finished with exit code 0", but does not show any output from print statement. Where am I going wrong ?
import urllib.request # instead of urllib2 like in Python 2.7
import json
def printResults(data):
# Use the json module to load the string data into a dictionary
theJSON = json.loads(data)
# now we can access the contents of the JSON like any other Python object
if "title" in theJSON["metadata"]:
print(theJSON["metadata"]["title"])
# output the number of events, plus the magnitude and each event name
count = theJSON["metadata"]["count"];
print(str(count) + " events recorded")
# for each event, print the place where it occurred
for i in theJSON["features"]:
print(i["properties"]["place"])
# print the events that only have a magnitude greater than 4
for i in theJSON["features"]:
if i["properties"]["mag"] >= 4.0:
print("%2.1f" % i["properties"]["mag"], i["properties"]["place"])
# print only the events where at least 1 person reported feeling something
print("Events that were felt:")
for i in theJSON["features"]:
feltReports = i["properties"]["felt"]
if feltReports != None:
if feltReports > 0:
print("%2.1f" % i["properties"]["mag"], i["properties"]["place"], " reported " + str(feltReports) + " times")
# Open the URL and read the data
urlData = "http://earthquake.usgs.gov/earthquakes/feed/v1.0/summary/2.5_day.geojson"
webUrl = urllib.request.urlopen(urlData)
print(webUrl.getcode())
if webUrl.getcode() == 200:
data = webUrl.read()
data = data.decode("utf-8") # in Python 3.x we need to explicitly decode the response to a string
# print out our customized results
printResults(data)
else:
print("Received an error from server, cannot retrieve results " + str(webUrl.getcode()))

Not sure if you left this out on purpose, but this script isn't actually executing any code beyond the imports and function definition. Assuming you didn't leave it out on purpose, you would need the following at the end of your file.
if __name__ == '__main__':
data = "" # your data
printResults(data)
The check on __name__ equaling "__main__" is just so your code is only executing when the file is explicitly run. To always run your printResults(data) function when the file is accessed (like, say, if its imported into another module) you could just call it at the bottom of your file like so:
data = "" # your data
printResults(data)

I had to restart the IDE after installing the module. I just realized and tried it now with "Run as Admin". Strangely seems to work now.But not sure if it was a temp error, since even without restart, it was able to detect the module and its methods.

Your comments re: having to restart your IDE makes me think that pycharm might not automatically detect newly installed python packages. This SO answer seems to offer a solution.

How to decode python string

I have some code which I would like to be decoded but not having much luck in guessing what the codepage is, if any is being used. Any help would be much appreciated.

The code is uglified. You can unobfuscate it yourself by executing the contents of exec(...) in your Python shell.
import re
import base64
print ((lambda p,y.....split("|")))
EDIT: As snakecharmerb says, it is generally not safe to execute unknown code. I analysed the code to find that running the insides of exec will only decrypt, and leaving off the exec itself will just result in a string. This procedure ("execute stuff inside exec") is by no means a generally safe method to decrypt uglified code, and you need to actually analyse what it does. But, at this point, I was asking you to trust my judgement, which, if it is wrong, theoretically could expose you to an attack. In addition, it seems you have problems getting it to run on your Python; so here's what I'm getting from the above:

Flask not writing to file

I've been meaning to log all the users that visit the site to a file.
Using Flask for the backend.
I have not been able to get python to write to the file. Tried keeping exception handling to catch any errors that might be generated while writing. No exceptions are being raised.
Here is the part of the blueprint that should write to file.
from .UserDataCache import UserDataCache
udc = UserDataCache()
#main.route('/')
def index():
s = Suggestion.query.all()
udc.writeUsertoFile()
return render_template('suggestions.html', suggestions = s)
Here is the UserDataCache class:
from flask import request
from datetime import datetime
class UserDataCache():
def __init__(self):
pass
def writeUsertoFile(self):
try:
with open("userData.txt","a") as f:
f.write(str(datetime.now()) + " " + request.remote_addr + " " + request.url + " " + request.headers.get('User-Agent') + "\n")
except IOError,e:
print e
return

I recommend using an absolute path and verifying the permissions on that file. Something like /tmp/UserData.txt or another absolute path should work. The web server's user is what needs the permission to write to the file (www-data if you're using apache2 with Ubuntu, or check your web server's conf file to verify).
As far as why you're not seeing the exception you're catching, I see you're using print. If you're calling the app using a web browser, you'll need to send the error to something else, like a log file or flash it to the browser, or raise an error so it gets logged in the web server error log.

Is your python file name begins with uppercase? If so, try to modify it into lowercase.
I just came into the same problem and copied the exactly same code into two .py file. The only difference is their file name, one being 'Flask_test.py' and another being 'flask_for_test.py'. It's weird that 'Flask_test.py' works just fine except it cannot write into any file and 'flask_for_test.py' works perfectly.
I don't know whether the format of the file name has an effect on the function of python but using lowercase file name works for me.
By the way, all other solutions I found didn't work.

Python newbie - Input strings, return a value to a web page

I've got a program I would like to use to input a password and one or multiple strings from a web page. The program takes the strings and outputs them to a time-datestamped text file, but only if the password matches the set MD5 hash.
The problems I'm having here are that
I don't know how to get this code on the web. I have a server, but is it as easy as throwing pytext.py onto my server?
I don't know how to write a form for the input to this script and how to get the HTML to work with this program. If possible, it would be nice to make it a multi-line input box... but it's not necessary.
I want to return a value to a web page to let the user know if the password authenticated successfully or failed.
dtest
import sys
import time
import getopt
import hashlib
h = hashlib.new('md5')
var = sys.argv[1]
print "Password: ", var
h.update(var)
print h.hexdigest()
trial = h.hexdigest()
check = "86fe2288ac154c500983a8b89dbcf288"
if trial == check:
print "Password success"
time_stamp = time.strftime('%Y-%m-%d_%H-%M-%S', (time.localtime(time.time())))
strFile = "txt_" + str(time_stamp) + ".txt"
print "File created: txt_" + str(time_stamp) + ".txt"
#print 'The command line arguments are:'
#for i in sys.argv:
#print i
text_file = open(strFile, "w")
text_file.write(str(time_stamp) + "\n")
for i in range(2, len(sys.argv)):
text_file.write(sys.argv[i] + "\n")
#print 'Debug to file:', sys.argv[i]
text_file.close()
else:
print "Password failure"

You'll need to read up on mod_python (if you're using Apache) and the Python CGI module.

Take a look at django. It's an excellent web framework that can accomplish exactly what you are asking. It also has an authentication module that handles password hashing and logins for you.
