如何在Python中找到列表的编号？

你能帮我查一下列表的编号吗？我想知道有多少张名单

from itertools import permutations

perm = permutations([0,1,2,3,4,5,6,7,8,9],4)

for i in list(perm):
    
    if 1 in i and 3 in i:
        print (i)

输出（一点）

创建一个变量来计算它们，而不是打印它们

one_and_three_count = 0
for i in list(perm):
    if 1 in i and 3 in i:
        one_and_three_count += 1
print("Number of lists containing 1 and 3:", one_and_three_count)

one_and_three_count = 0
for i in list(perm):
    if 1 in i and 3 in i:
        one_and_three_count += 1
print("Number of lists containing 1 and 3:", one_and_three_count)
