Find the index of the first digit in a string

Question

I have a string like

\"xdtwkeltjwlkejt7wthwk89lk\"

how can I get the index of the first digit in the string?

Answer 1

Thought I'd toss my method on the pile. I'll do just about anything to avoid regex.

sequence = 'xdtwkeltjwlkejt7wthwk89lk'
i = [x.isdigit() for x in sequence].index(True)

To explain what's going on here:

• [x.isdigit() for x in sequence] is going to translate the string into an array of booleans representing whether each character is a digit or not
• [...].index(True) returns the first index value that True is found in.
