How to detect string initial in python?

Question

For example I have a string:

"Hello My name is Ralph"

is there any way I could detect HM ni R ?

Answer 1

try :

myText = "Hello My name is Ralph"
print [x[0] for x in myText.split()]

Answer 2

If you wanted to do this with a regex, this would work:

re.findall(r'\b(\w)\w*\b',MY_STRING)

How this works:

\\b is a word boundary. You can check for a word in regex by using \\bWord\\b , and it will return a match for Word

(\\w) This is a group, matching a single letter. Since this is the only group, this is what is returned as the "match" by the regex

\\w* This searches for additional letters in a row, of any length or no length. You didn't include any punctuation, but if you wanted the regex to not break on apostrophes you could change this to something like [\\w\\']* instead
