like for +43 and +49 a working regex, mine is not working
In my regex the numbers are also matched and not only just the telephone numbers.
Has anyone a solution to that?

In Ruby, I want to see if user input contains any letter in the alphabet.
I have tried using contains and include?, but neither of these worked.
See String#include?
For example:
myString.include? 'a'
Similar to the comment from Cary: use a regular expression (regexp):
puts ‘matches’ if in_str =~ /[A-Za-z]/

My code looks fine to me, but I'm getting a syntax error in my for loop. Does anyone know why this would be the case? I've included my code below:
def printLine(numberOfDots):
dots = 0
for x in range numberOfDots:
dots += 1
printDots = print("." * dots)
return printDots
printLine(20)
range is a function, so you should use range(numberOfDots) instead of range numberOfDots.
