Removing rows that contain empty column without pandas

Question

a_list = [ ["a", ""], ["b", "2"] ]

I have a list of lists as written above. Any suggestions on how to remove the row that contains an empty element (in this case the first list), without using pandas, so it returns:

a_list = [ ["b", "2"] ]

Answer 1

Try:

a_list = [["a", ""], ["b", "2"]]

a_list = [l for l in a_list if "" not in l]
print(a_list)

Prints:

[['b', '2']]
