I need to test strings to determine if one of a list of chars is in the string. A simple example would be to test strings to determine if they have a vowel (aeiouAEIOU) present. I was hopeful that there was a built-in method that operated similar to startswith where I could pass a tuple of chars to be tested, but I could not find such a method. Which of the following techniques is most Pythonic or are there better ways to perform this type of match? # long and hard coded but short circuits as soon as match found if 'a' in word or 'e' in word or 'i' in word or 'u' in word or ... : -OR- # flexible, but no short circuit on first match if [ char for char in word if char in 'aeiouAEIOU' ]: -OR- # flexible, but no short circuit on first match if set( word ).intersection( 'aeiouAEIOU' ): Thank you, Malcolm
