You can convert any list comprehension into an equivalent explicit loop as follows:

pairs = []
for s1 in qs.split('&'):
    for s2 in s1.split(';'):
        pairs.append(s2)

The rule is to take all the offers forand ifenclose them in the order in which they appear, and then append(foo)for any foountil the first sentence.
