How to count the number of elements in a string in ruby?

Question

ruby

There is a line like this

f = '1232132131, 12321321, 34232423423, 324234234234'

You need to count the number of elements. I know that this option works for a list of words. How can I convert it into a version with numbers, or maybe there is an easier way?
f.split(/[^-a-zA-Z]/).size

Answer 1

f = '1232132131, 12321321, 34232423423, 324234234234'
f.split.size ## 4
f.split(', ').size ## 4, вот так корректней
