Using OR operator in NumPy Array to Append multiple items
Instead of doing the "OR" inside the append, you'll need to do an if statement: if category == 'bulky item': items.append((Address, x, y, x, y, ReasonCode, SRNumber, SRNumber, FullName, ResolutionCode, HomePhone, CreatedDate, UpdatedDate, BulkyItemInfo, k_bulky_comm, ServiceDate, CYLA_DISTRICT, SCCatDesc, # ServiceNotes, Prior_Resolution_Code, CYLA_DISTRICT, )) elif category == 'e-waste': items.append((Address, x, y,...
Reading inputs written in different lines from a file and storing each input inside a list
print list(open("my_text.txt")) is probably a pretty easy way to do it ... ofc people are gonna come screaming about dangling pointers so for the sake of good habits with open("my_text.txt") as f: print list(f) alternatively f.readlines() you might need to strip off some newline characters [line.strip() for line in f]...
Adding time/duration from CSV file
python,python-2.7,csv,datetime
Use datetime.timedelta() objects to model the durations, and pass in the 3 components as seconds, minutes and hours. Parse your file with the csv module; no point in re-inventing the character-separated-values-parsing wheel here. Use a dictionary to track In and Out values per user; using a collections.defaultdict() object will make...

How to skip a function
If I you're asking what I think you're asking, then yes. In fact, that's the whole point. Functions are sections of reusable code that you define first (they don't run when they're defined!) and then you call that function later. For example, you can define a function, helloworld like this:...

How to find longest consistent increment in a python list?
One problem (but not the only one) with your code is that you are always adding the elements to the same possible_list, thus the lists in bigger_list are in fact all the same list! Instead, I suggest using [-1] to access the last element of the list of subsequences (i.e....

How can I detect a URL really exists despite a 301 or 302 redirect?
