Help me with global

Question

When creating a discord bot, when I wanted to import data from a file, I had a problem with the "for" loop. More precisely, with the variable "d".
Code:
class Data(object):
def __init__(self):
with open("data.dt", "r") as file:
l = file.readlines()
self.wl = l[0].split() # whitelist
s = l[1].split()
for i in s:
k = i.split(":")
d[k[0]] = k[1]
self.score = d # score
del s, k, d
data = Data()
Error:
UnboundLocalError: local variable 'd' referenced before assignment
I tried to put "global d" both before loop and inside it, before the "Data" class and in many other places. I get an error like "NameError: name "d" is not defined".

Answer 1

I have already solved the problem without "global". But I don't know how :D

class Data(object):
def __init__(self):
with open("data.dt", "r") as file:
l = file.readlines()
self.wl = l[0].split() # whitelist
d = {}
for x in list(l[1].split()):
s = x.split(":")
d[s[0]] = s[1]
self.score = d # score
del d
data = Data()

Answer 2

in your solution you have defined a variable 'd' as an empty dict before the loop, so in the loop you can access it without problem ;P

however, you doesn't need to explicitly delete it, as local variable live only during function/method run (since you doesn't capture the scope by returning some function defined in that scope) ^^

Answer 3

all that means is that you tried to acces a variable (d) that wasn't created yet. what where you trying to do with that line

d[k[0]] = k[1]

visph Thank you :)
