Question

I\'m building a website with Python/Django. Users submit tags. Each tag can contain multiple words. Each tag has an ID number. I want to make sure tags that are formatted sl

Answer 1

"electric guitar".split() will give you ['electric', 'guitar']. So will "electric \tguitar".

Answer 2

This function removes everything which is not digit in a string. I use it all over the place.

def parseInt(string):
    if isinstance(string, (str, int, unicode)):
        try:
            digit = int(''.join([x for x in string if x.isdigit() ]))
        except ValueError:
            return False
        else:
            return digit
    else:
        return False   

Answer 3

I would use Django's slugify method, which condenses spaces into a single dash and other helpful features:

from django.template.defaultfilters import slugify

Answer 4

Split on any whitespace, then join on a single space.

' '.join(s.split())

Answer 5

There could be many white spaces like below:

var = "         This      is the example  of how to remove spaces   "

Just do simple task like, use replace function:

realVar = var.replace(" ",'')

Now the outpur would be:

Answer 6

>>> import re

'some test with ugly whitespace'
