Removing empty items from a list (Python)

I'm reading a file in Python that isn't well formatted, values are separated by multiple spaces and some tabs too so the lists returned has a lot of empty items, how do I remove/avoid those?

This is my current code:

import re

f = open('myfile.txt','r') 

for line in f.readlines(): 
    if re.search(r'\bDeposit', line):
        print line.split(' ')

f.close()

Thanks

for line in open("file"):
    if " Deposit" in line:
         line=line.rstrip()
         print line.split()

Update: 

for line in open("file"):
    if "Deposit" in line:
         line=line.rstrip()
         print line[line.index("Deposit"):].split()

linesAsLists = [line.split() for line in open('myfile.txt', 'r') if 'Deposit' in line)]

Don't explicitly specify ' ' as the delimiter. line.split() will split on all whitespace. It's equivalent to using re.split:

>>> line = '  a b   c \n\tg  '
>>> line.split()
['a', 'b', 'c', 'g']
>>> import re
>>> re.split('\s+', line)
['', 'a', 'b', 'c', 'g', '']
>>> re.split('\s+', line.strip())
['a', 'b', 'c', 'g']

Why not do line.strip() before handling it? Also, you could use re.split to use a regex like '\s+' as your delimiter.
