Match multiple strings using re.search within an if condition - regex

Question

I am writing a program to create a list from a spreadsheet based on a position value in another cell. So my code looks like
for j in xrange(1,13):
for sheet in wb.sheets():
for i in xrange(1,12*15):
team=sheet.cell(i,0)
position=sheet.cell(i,2)
games=sheet.cell(i,23)
if re.match(owner[j], str(team.value)) and (not re.findall('Defense' or 'K,' or 'KFG' or 'KKO', str(position.value))):
try:
list.append(int(games.value))
except ValueError:
list.append(0)
else:
pass
print list
list=[]
So the goal of this is to append to a list when a row matches owner in the first column, and not Defense K, KFG KKO in the position column.
Unfortunately, the values for K, KFG and KKO all show
up in my lists, but the Defense values properly do not. How can I
ensure the other filtering criteria are met?
As a side note, these positions are in amongst other bits of text so
the search() is used here instead of match().

Answer 1

"Defense" is a 'truthy' value, so the result of:
'Defense' or 'K,' or 'KFG' or 'KKO'
is 'Defense'.
Therefore, the condition you have is no different from:
re.match(owner[j], str(team.value)) and (not re.findall('Defense', str(position.value)))
If you want alternatives in a regex, use | in the pattern:
re.match(owner[j], str(team.value)) and (not re.findall('Defense|K,|KFG|KKO', str(position.value)))
