(ix)

print(mySubject.startswith('Comp'))

Answer

True

(x)

print(mySubject.isalpha())

Answer

False

Explanation

The string mySubject = 'Computer Science' has 16 characters (indices 0-15). Each operation uses different string concepts: (i) slicing from 0 to length returns the full string; (ii) negative indexing where -7='S' and -1='e'(exclusive) gives 'Scienc'; (iii) step 2 extracts even indices; (iv) last character accessed via length-1; (v) repetition operator duplicates string; (vi) negative step traverses backwards; (vii) concatenation rejoins split parts; (viii) swapcase inverts case; (ix) startswith checks prefix; (x) isalpha returns False due to space character.
