tmplist = [True, True, False, True, False]
idx = []
for i in range(len(tmplist)):
    if tmplist[i] == True:
        idx.append(i)
        
print(idx)

tmplist = [True, True, False, True, False]
print([i for i in range(len(tmplist)) if tmplist[i] == True])

pythonic solution should be as followint:
from itertools import compress
mask = range(5)
tmplist = [True, True, False, True, False]
print(list(compress(mask, tmplist))

from itertools import compress
tmplist = [True, True, False, True, False]
mask = []
for i in range(5):
    mask.append([i for i in range(len(tmplist)) if tmplist[i] == True])
print(list(compress(mask, tmplist)))

要的是下面的结果？

[[0, 1, 3], [0, 1, 3], [0, 1, 3]]

嗯，非常感谢
