comparing lists to columns in a txt file

Question

I'm trying to read the 5th column of a file in python. If the third column matches "Plop" I store the third column in a list1, otherwise if the fifth column matches "toto" I store the third column in a list2. Then all I do is I check the lenght of every element in both lists. When I run my code I get this error:

if word1 in columns[:4]
                      ^
SyntaxError: invalid syntax

My code is as follow:

word1=['Popo']
word2=['toto']
aList1 = list()
aList = list()

for line in open("test.txt"):
    columns = line.split(" ")
 #columns.lookup([toto])
    if word1 in (columns[:4]):
        aList1.insert(columns[:2])
    if word2 in (columns[:4]):
        aList.insert(columns[:2])

#print '\n'.join(aList1)

for entry in aList1:
    try:
        l = len(entry)
        print "Length of", entry, "is", l
    except:
        print "Element", entry, "has no defined length"

for entry in aList:
    try:
        l = len(entry)
        print "Length of", entry, "is", l
    except:
        print "Element", entry, "has no defined length"

您到底缺少了： ，应该是：

if word1 in columns[:4]:
