Split string based on regex

Question

What is the best way to split a string like  HELLO there HOW are YOU  by upper case words  in Python     So I d end up with an array like such  results     HELLO there    HOW are    YOU      EDIT    I have tried    p   re compile   b A-Z  2   b   print p split page text    It doesn t seem to work  though

Your question contains the string literal   b A-Z  2   b   but that  b will mean backspace  because there is no r-modifier   Try  r  b A-Z  2   b

I suggest  l   re compile     lt     s     A-Z       s    split s    Check this demo

You could use a lookahead   re split r        A-Z   b    input    This will split at every space that is followed by a string of upper-case letters which end in a word-boundary   Note that the square brackets are only for readability and could as well be omitted   If it is enough that the first letter of a word is upper case  so if you would want to split in front of Hello as well  it gets even easier   re split r        A-Z     input    Now this splits at every space followed by any upper-case letter
