Suppose I have the following string:

abc,400,00,foo,bar,34,000,,hello,bye

What would the proper regex be to match the number of commas that have a character both on the left and right side though both characters can't be numeric, and non can be other commas.

In the example string, the commas I placed inside the parentheses would be counted, the rest not.

abc(,)400,00(,)foo(,)bar(,)34,000,,hello(,)by

You can user OR in your regex with two possible cases

This should also work -

(?<=[^\d,]),
