Whatever is the code, i'm just searching for the way to disable some lines directly in one time by char "#".
For example, i have this code :
import json
def get(user):
try:
with open("tokens.json") as f:
data_token = json.load(f)
f.close()
return str(data_token["tokens"][user])
except:
return False
def check(user, token_key):
with open("tokens.json", 'r') as f:
data_tokens = json.load(f)
f.close()
for ids, tokens in data_tokens["tokens"].items():
if str(ids) == str(user):
if int(tokens) == int(token_key):
if __name__ == '__main__':
print(get("User1"))
And i temporary want to disable my fonction named "check()" because it makes a error right now :
import json
def get(user):
try:
with open("tokens.json") as f:
data_token = json.load(f)
f.close()
return str(data_token["tokens"][user])
except:
return False
#def check(user, token_key):
# with open("tokens.json", 'r') as f:
# data_tokens = json.load(f)
# f.close()
# for ids, tokens in data_tokens["tokens"].items():
# if str(ids) == str(user):
# if int(tokens) == int(token_key):
if __name__ == '__main__':
print(get("User1"))
I already seen some guys doing that and i wanted to know how to do.
Thanks ;)

Anybody can advise what could be wrong with my code?
I am trying to make a method that removes the single line comments from the content.
Also, the method should return the single line comments that start with '#'.
import os
def deleteComments(file):
try:
my_file = open(file, 'r')
data = my_file.read()
clean = ""
comment= 0
if i[0] == "#":
comment += 1
else:
pass
with open("clean-", "w") as f:
f.write(clean)
f.close()
my_file.close()
except:
print("An error occurred with accessing the files")
return file
def deleteComment(file):
try:
my_file = open(file, 'r')
data = my_file.read()
clean = ""
comment= 0
if i[0] == "#":
comment += 1
else:
pass
with open("clean-", "w") as f:
f.write(clean)
f.close()
my_file.close()
except:
print("An error occurred with accessing the files")
return file
This should make it work.
import os
def deleteComments(file):
try:
my_file = open(file, 'r')
data = my_file.read()
clean = ""
comments_count = 0
for i in data.split('\n'):
if i[0] == "#":
clean += i
clean += '\n'
comments_count += 1
else:
pass
name = os.path.basename(path)
with open("clean-" + name, "w") as f:
f.write(clean)
f.close()
my_file.close()
return comments_count
except:
print("An error occurred with accessing the files")
return file
Error - Error: No such option: --addtask

Saw several youtube videos still couldnt fix it
Pls help!
code below

I have a pickle db with 5 variable in it that goes : rafTur, rafKat, rafNo, rafIndex, rafIndexData. I'm trying to delete a data inside my pickle file. My main goal is taking an input from user that goes like this :
rafTur = S rafKat = 1 rafNo = 2 rafIndex = 3
And then finding that imput from my pickle file that named noSqlDB. and then delete the entire data about input.
def delPic():
infile = open('noSqlDB', 'rb+')
sistem = pickle.load(infile)
flag = False
rafTur = str(input('Rafın türünü giriniz : '))
rafKat = int(input('Rafın katını giriniz : '))
rafNo = int(input('Rafın Nosunu giriniz : '))
rafIndex = int(input('Rafın indexini giriniz : '))
# read to the end of file.
for x in range((len(sistem) + 1)):
try:
if (sistem['rafTur'].upper() == rafTur.upper() and sistem['rafKat'] == rafKat and sistem['rafNo'] == rafNo and sistem['rafIndex'] == rafIndex):
del sistem
flag = True
sistem = pickle.load(infile)
except EOFError:
break
if flag == False:
print('Record not Found')
infile.close()
When i run this code nothing changes. The data stays on noSqlDB. How can i delete the data inside the noSqlDB ? like this
I tried changing
del sistem
to
del sistem['rafTur'],sistem['rafKat'], sistem['rafNo'],sistem['rafIndex'],sistem['rafIndexData']
def unpickle_database(filename):
with open(filename, 'rb') as f:
while True:
try:

except EOFError:
break
def save_object(obj, filename,a):
if a < 1:
with open(filename, 'wb+') as output:
pickle.dump(obj, output, pickle.HIGHEST_PROTOCOL)
else :
with open(filename, 'ab+') as output:
pickle.dump(obj, output, pickle.HIGHEST_PROTOCOL)
def delPic():
temp =0
students = list(unpickle_database('noSqlDB'))
for student in students:
print(student)
save_object(student, 'noSqlDB',temp)
temp += 1
Found a solution after trying some code here it is.
def test(file_name):
if file_name.lower().endswith('.gz'):
with gzip.open(file_name) as f:
f_csv = csv.reader(i.TextIOWrapper(f))
#### Same Code
if file_name.lower().endswith('.csv'):
with open(file_name) as f:
f_csv = csv.reader(i.TextIOWrapper(f))
#### Same Code
Question> Is there a better way to combine the above code without duplicating the 'Same Code' section? The function test uses gzip.open if the the file_name is a gz file otherwise it opens with regular open.
One way would be:
def test(file_name):
loader = None
if file_name.lower().endswith('.gz'):
loader = gzip.open
elif file_name.lower().endswith('.csv'):
loader = open
if loader is not None:
with loader(file_name) as f:
f_csv = csv.reader(i.TextIOWrapper(f))
#### Same Code
def test(file_name):
f = None
if file_name.lower().endswith('.gz'):
f = gzip.open(file_name)
if file_name.lower().endswith('.csv'):
f = open(file_name)
if f is not None:
f_csv = csv.reader(i.TextIOWrapper(f))
#### Same Code
f.close()
I'm running Python 3 and I'm getting the following error:
AttributeError: 'AssemblyParser' object has no attribute 'hasMoreCommands'
Here is the code that is raising the error:

Here is my Parser.py file:

I really don't know why I'm getting this error, I've looked at the import documentation, but I'm getting more and more confused. I'm fairly new to Python. Can anyone explain this error?
Thanks.
Well. There seems to be no function in Parser module with name hasMoreCommand. The function in there starts with underscore and end eith underscore.
Two leading and trailing underscores are used to identify "magic" attributes. You can't use that to create your own, as they only reference pre-existing methods.
The following is what you probably want:
hasMoreCommands():
If you have multiple classes with this function, use name mangling instead:
_hasMoreCommands():
