How to check if an object produced by zip() is empty?

Question

If I have lists like these:

transactions = ['001','002','003']

transaction_dates = ['01-01-2019','01-02-2019','01-03-2019']

transaction_amounts = ['27.00','35.00','36.00']

And I use zip like this

results = zip(transactions,transaction_dates,transaction_amounts)

How do I tell if results is empty?

Answer 1

Since zip will return an iterator you can just use the next method to iterate over the zipped item and if it leads to StopIteration exception then it indicates that the list is empty like this:

def is_empty(items):

    try:

    next(items)

    return False

    except StopIteration:

    return True
