python print next word in a file -


i have error on code here print next word/string contained on file

for in cursor.fetchall():     keywords.append(i[0])  open('qwer.txt','r') file:     line in file:         key in keywords:             if key in line:                 line = line.split(". ")                 j in range(len(line)):  <----error(str obj not callable)                     print line[key(j+1)]    <----error 

print line[key(j+1)]

is attempt call key single argument j+1. however, key string can't called. think meant use index key[j+1], won't integer attempt index line fail.

i think want is:

line[line.index(key) + 1]

really should checking key in line after split:

with open('qwer.txt','r') file:     line in file:         line = line.split()         key in keywords:             if key in line:                 print line[line.index(key)+1]
