Python (String manipulation Example 1) A string separated by a space

# separate words in words with spaces
# only letters are known in the passed-in string, with the first letter of each word capitalized,
# Separate each word with a space, leaving only the first letter capitalized in: "HelloMyWorld"
# return to "Hello My World"


# given a string
INSTR = "HelloMyWorld"
# Convert strings to lists
Str_list = List (INSTR)

# take out each element with a loop
For I in INSTR:
    # Determine if an element is uppercase
    If I.isupper ():
        # if it's uppercase, record the subscript position
        index = Str_list.index (i)
        # Judging if it's the first letter, jump out of this loop
        If index = = 0:
            Continue
        # Modify data, convert uppercase to Cheng and add spaces
        Str_list[index] = I.lower ()
        Str_list.insert (Index, "")

        # Convert to String
        outstr = "". Join (Str_list)
Print (OUTSTR)
