Iterating over an empty list within a list

take following code example:

a = [['james dean'],['marlon brando'],[],[],['frank sinatra']]  n = 0  in a:     print a[n][0]     n = n + 1

i seem getting error index value:

indexerror: list index out of range

how skip on empty lists within list named a?

you can check if list empty or not, empty lists have false value in boolean context -

for in a:     if i:         print a[n][0]     n = n + 1

also, instead of using n separately, can use enumerate function , returns current element index -

for n, in enumerate(a):     if i:         print a[n][0] # though - print i[0]
