Not counting empty list while counting total lists count in Python

Question

I have 3 lists out of which 1 is empty. I want to take count of lists in a list which are not empty.

For example:

 a = ['username', 'username', 'social']
 b = []
 c = ['username', 'instead', 'added']

Combining all the lists together:

combine = [a,b,c]

Counting the non-empty lists:

count = sum(x is not '' for x in combine)

When I am running the above code, I have getting 'count=3' but I want 'count=2'

Please help me how should this can be done.

Okay, so in that case I don't want to take count of [] and take count of rest. — adi5257, Mar 26 '18 at 07:50
You should just be able to do `sum(map(bool, combine))` or `sum(bool(x) for x in combine)` — cs95, Mar 26 '18 at 07:51

try

count =sum(len(x)>0 for x in combine)
