Make Python Sublists from a list using a Separator

Question

I have for example the following list:

[\'|\', u\'MOM\', u\'DAD\', \'|\', u\'GRAND\', \'|\', u\'MOM\', u\'MAX\', u\'JULES\', \'|\']

and wan

Answer 1

Simple solution using plain old for-loop (was beaten to it for the groupby solution, which BTW is better!)

seq = ['|', u'MOM', u'DAD', '|', u'GRAND', '|', u'MOM', u'MAX', u'JULES', '|']

S=[]
tmp=[]

for i in seq:
    if i == '|':
        S.append(tmp)
        tmp = []
    else:
        tmp.append(i)

# Remove empty lists
while True:
    try:
        S.remove([])
    except ValueError:
        break

print S

Gives

[[u'MOM', u'DAD'], [u'GRAND'], [u'MOM', u'MAX', u'JULES']]
