Get first non-empty string from a list in python

Question

In Python I have a list of strings, some of which may be the empty string. What\'s the best way to get the first non-empty string?

Answer 1

to get the first non empty string in a list, you just have to loop over it and check if its not empty. that's all there is to it.

arr = ['','',2,"one"]
for i in arr:
    if i:
        print i
        break
