You need to take every second character in the string and convert it to upper case.
This is how I get and output every second character:
a = 'future' b = a[::2] print(b)
How to output other characters along with them?
Another short solution:
"".join([x.upper() + y for x,y in zip(a[::2], a[1::2])]) >>> 'FuTuRe'
