Visual Studio Code, Python, Alterations Not Running

I am trying to alter some code I have been given for my dissertation. However, any alterations to the modules (print statements, logging, and even trying to deliberately break the code with breaks) do not seem to affect the main program running as if those changes were not there, but changes to the main program does affect the output.
All the changes are saved and I have tried reimporting all the data files I am using and deleting all of the results before rerunning to try and start the program from "fresh". But no luck in fixing the issue.
Is there any fix to this problem? Apologies if it is an easy one, still starting out.
Main Program
eda = EDA()
cdr3_lengths = eda.get_length_of_repertoires(
repertoires=repertoires,
cdr3_col_name="aaSeqCDR3",
freq_col="cloneCount",
groups={
"01.TC8.14": "14days",
"02.TC4.14": "14days",
"03.SC8.14": "14days",
"04.SC4.14": "14days",
"05.TC8.21": "21days",
"06.TC4.21": "21days",
"07.SC8.21": "21days",
"08.SC4.21": "21days",
},
)
Module
class EDA:
# --init method etc --
def get_length_of_repertoires(
self,
repertoires: List,
groups: dict,
cdr3_col_name: str,
freq_col: str,
save_df: bool = False):
print("This isn't working")
cdr3_lengths = {}
self.logger.info("For loop fetching each repertorie.")
for repertoire in repertoires: #Repeat seqs len for count
self.logger.debug(repertoire)
.....
return 'value'
I have added some of the code that I am working with here, I believe it is being executed. I hope this helps a little more.

Random.Choice always the same result

Some pretext that's maybe useful idk. I use mixer and am trying to do a random music choice but the random.choice always take the last one (song 5). This is my code
if Mamp=='1':
vad=input("[1] Bakground music")
#Mixer shit
mixer.init()
pygame.mixer.get_init
if vad=='1':
commands=[mixer.music.load("song1.mp3"), mixer.music.load("song2.mp3"),mixer.music.load("song3.mp3"),mixer.music.load("song4.mp3"),mixer.music.load("song5.mp3")]
current_command=random.choice(commands)
current_command
mixer.music.play(0)
I looked at many answers for the same problem but all wer're just fixing thier (the uploader's) code and uploaded it so I couldn't use it for my code. And since i'm trying to learn python it would be great if you could also explain what went wrong?

commands=[mixer.music.load("song1.mp3"), ...]
current_command=random.choice(commands)
current_command
You're doing this part all wrong.
It seems like you want to make a list of commands to be executed later, but that's not what you're actually doing. The load() commands are actually executed when the commands list is created.
And because song5.mp3 is the last one, it gives the appearance of being "picked" every time.
Try it this way instead:
songs = ["song1.mp3", "song2.mp3", "song3.mp3", "song4.mp3", "song5.mp3"]
song = random.choice(songs)
mixer.music.load(song)

python- cannot run a simple pro

hi im a beginner of python and linux. im using visual studio code and python 3.5.2
im trying to run something very simple unsuccess . tnx
so this is my code:
import random
def randomNumber():
n=random.randint(1,100)
print (n)
checkMatch(n)
def checkMatch(compNum):
playerNum= int(input("choose num between 1 to 100: "))
if playerNum==compNum:
print ("congratulation you won!")
elif playerNum<compNum:
print ("sorry but the num you choose is smaller then the right answer")
else:
print("sorry but the num you choose is bigger then the right answer")

The code presented has nothing which would be expected to run, as such. You define two functions, but they are never called and so nothing happens.
Try adding randomNumber() at the end, I think that then the program will work as intended.

You didn't call the function to run. Add randomNumber() to the end of your program. Were you getting an error with your if statements? Please edit your post if you were. It is working fine for me.

Python Global Variable Not Working

I have an extremely long program for a Canasta game that I am writing, in it there is a variable that ends the turn of the player if it equals a certain value. However, the turn repeats itself.
I have read many different articles and posts on forums like this one, but none of these seem to work. I even have a debug system to print the value of the variable before the if statement, and the variable is the right value, but the if statement doesn't see the same value.
I can't give the entire code, as it is extremely long, but I can give the sections that use this variable. I am using Python 2.7.2 and cannot make files separate from the main file to import.
The first line of the program is:
endTurn=1
The following function is called when conditions to win the game are met, but I have not been able to test that this works because of the bug.
def winGame(player):
global endTurn
gameWinner=player
gameWinner["score"]+=100
endTurn=0
The following function is called when a move is made. The variable decide is a raw_input() variable.
def move(player,decide):
global endTurn
theMove=decide.lower()
#if player says to end turn
if theMove=="end":
#until player discards something
discarded=0
while not discarded:
displayHand(player)
#ask player for discard
discard=int(raw_input(" Enter the list number of the card you wish to discard:"))-1
#if discard ID is in player's hand length
if not discard<0 and not discard>len(player["hand"])-1:
#add card to discard pile and remove from hand
discardPile.append(player["hand"][discard])
del(player["hand"][discard])
discarded=1
debug("Before changing, endTurn is %s"%str(endTurn))
endTurn = 0
debug("After changing, endTurn is %s"%str(endTurn))
if theMove=="new book":
newBook(player)
if theMove=="add to book":
addBook(player)
Here is where the turn should be ended. turn(thePlayer) repeats the function. The debug statement shows the correct value, 0, but the if still reads a 1. The function this is in also has the global endTurn at the top.
debug("If ending turn, endTurn of %s should be 0."%str(endTurn))
if endTurn==1:
turn(thePlayer)
Any help is greatly appreciated!
EDIT: The code is available at http://labs.codecademy.com/CV9z#:workspace. I ask that anyone viewing the code does not modify it, so that other people can see the true code.

I fixed the bug. I removed the endTurn variable and instead made the function that ends the turn just do the turn of the next player. It also simplified my code a bit.
I am wondering though, is using this method of running a function inside of itself over and over and over again (without leaving) rather messy or maybe slowing down my program?
EDIT: I now realize that this answer does not exactly help with anyone else who is stuck with global variables...

The previous answer I posted was just wrong, as it was based on a misinterpretation of the namespace docs as I had read them (Thanks to TheifMaster for pointing out my error), so this is a SEVERELY EDITED ANSWER:
The problem is in the while loop that I was able to read when the link to the entire code was posted after the erroneous answer I gave earlier.
while gameWinner==0:
endTurn=1
turn(player1)
if not gameWinner==0:
endTurn=1
turn(player2)
The game can never get to player two in this loop until gameWinner!=0.
I added the entire code to my sandbox and changed it to:
while gameWinner==0:
endTurn=1
turn(player1)
if gameWinner==0: #if player1 did not win yet
endTurn=1
turn(player2)
However, the game is still buggy... No one can win! gameWinner is not changed globally by the winGame() function until you add it to the global statement as I have shown here.
def winGame(player):
global endTurn, gameWinner
gameWinner=player
gameWinner["score"]+=100
debug("gameWinner == " + str(gameWinner))
endTurn=0

Python Will Not Launch External Applications Using os.system(<filepath here>)

Been using easygui in python to make gui boxes for various different system applications for windows over the past few days. What I want to know is, why doesn't my code work? It looks the same as the code that was working before? The program is a game launcher, and I shall be making one identical to this but working (with different, LAN compatible games) for people to select the game from the list. Looked on stack overflow and found somebody with a similar issue, however I don't believe his resolution would apply to my script. Will post code below,
thank you,
Matthew
import easygui as eg
import os
def menu():
msg="Please select a game:"
title="Select Game!"
choices=["Batman Arkham City", "Tomb Raider", "TESV Skyrim", "State of decay - Early Access", "Critical Strike Portable", "Terraria", "Doom", "Halo","Minecraft"]
reply=eg.buttonbox(msg,title,choices)
if choices=="Batman Arkham City":
batman()
elif choices=="Tomb Raider":
tomb()
elif choices=="TESV Skyrim":
skyrim()
elif choices=="State of decay - Early Access":
state()
elif choices=="Critical Strike Portable":
crs()
elif choices=="Terraria":
terr()
elif choices=="Doom":
doom()
elif choices=="Halo":
halo()
elif choices=="Minecraft":
minecraft()
def batman():
os.system('"C:\Program Files (x86)\Black_Box\Batman Arkham City\Binaries\Win32\BatmanAC.exe"')
menu()
def tomb():
os.system('"C:\Program Files (x86)\Tomb Raider\TombRaider.exe"')
menu()
def skyrim():
os.system('"C:\Program Files (x86)\The Elder Scrolls V Skyrim\SkyrimLauncher.exe"')
menu()
def state():
os.system('"C:\Games\State of Decay Early Access\StateOfDecay.exe"')
menu()
def crs():
os.system('"C:\Program Files (x86)\CS Portable\a.exe"')
menu()
def terr():
os.system('"C:\Games\Terraria\Terraria.exe"')
menu()
def doom():
os.system('"C:\DOOMWADS\doom.wad"')
menu()
def halo():
os.system('"C:\Program Files (x86)\Halo Combat Evolved\Halo.exe"')
menu()
def minecraft():
os.system('"C:\Games\minecraft.exe"')
menu()
menu()
Stack overflow has messed up my indents! Please assume these are correct as they are.

It's the backslashes that are causing the problem. Python interprets these itself, e.g. \n is a new line character.
Change them either to forward slashes, or to double backslashes.
os.system('"C:/DOOMWADS/doom.wad"')

I have fixed it.... Sorry for wasting anybodies time. The backslashes are fine because they are in '""', however in the menu section is "if choices=="game"" whereas it should be, "if reply=="game"". Thanks for the help! :)
