第二个-从list2中查找每两项的组合.

Second- Finding combinations of each two item from list2.

第三项-从list1和list2中查找每两项的组合

Third- Finding combinations of each two items from list1 and list2

第四次-计算每种组合的总长度

Fourth- Calculating each combinations total length

推荐答案

import itertools as it

list1=['12aa','2a','c2']
list2=['2ac','c2a','1ac']

# First- Finding combinations of each two item from list1.
first = list(it.combinations(list1, 2))

# Second- Finding combinations of each two item from list2.
second = list(it.combinations(list2, 2))

# Third- Finding combinations of each two items from list1 and list2
third = list(it.product(list1, list2))

# Fourth- Calculating each combinations total length
for combination in first: # first, second, third
    print combination, len(''.join(combination))
