# Write code to split a string at uppercase letters

# findall() returns the occurrences of the pattern in the target string
#    - create a list of occurrences of a pattern in a string
#    - group(), start(), end() not applicable
# search() gives more information than just the actual patterns
#    - tell where the pattern occurs in the target string
#    - returns a match object for the first occurrence
#    - returns None if pattern is not found
# match() checks if the pattern exists at the very *start* of a string
#    - returns None if pattern not found
#      note: Python processes None as False
# finditer() creates a list (or an iterator) of match objects for where
#      the pattern occurs in a string
#    - thus, can iterate a list of match objects and use group(), start(), end()
