Repeating 3 times

If what you mean is that the string "Triple" is to be treated as a keyword whose following string's value is to be replaced by itself tripled, then the following can accomplish what you want:

def tripler(s):
    triples = 0
    s = [ss.strip() for ss in s.split()][::-1]

    for i in range(len(s) - 1):
        if s[i - triples + 1] == 'Triple':
            s[i - triples] *= 3

            del s[i - triples + 1]
            triples += 1

    return ' '.join(s[::-1])

Dynamic repetitions

To repeat the argument any number of times, a dictionary with different keywords and corresponding values could be used:

repeat_keywords = {'Double':2, 'Triple':3}

def repeater(s):
    repeats = 0
    s = [ss.strip() for ss in s.split()][::-1]

    for i in range(len(s) - 1):
        if s[i - repeats + 1] in repeat_keywords:
            s[i - repeats] *= repeat_keywords[s[i - repeats + 1]]

            del s[i - repeats + 1]
            repeats += 1

    return ' '.join(s[::-1])

Inputs:
1. Double x Triple y
2. Double Triple y
3. Triple x Double Double y Triple z Double

Outputs:
1. xx yyy
2. yyyyyy
3. xxx yyyy zzz Double


Note: this solution also has the effect of multiplying the value of repeated keywords. That is due to parsing the string in reverse.
