I just started studying Python and created some kind of task for myself that I\'m struggling to solve...

So, I\'m on chapter on working with strings (accessing strin

Answer 1

You could just use enumerate and test for odd and even indices using a ternary operator. Then use join to join the string:

>>> T = 'somesampletexthere'
>>> ''.join(x.upper() if i%2 else x.lower() for i, x in enumerate(T))
'sOmEsAmPlEtExThErE'

You could handle whitespaces by using an external counter object provided by itertools.count:

>>> from itertools import count
>>> c = count()
>>> T = 'some sample text here'
>>> ''.join(x if x.isspace() else (x.upper() if next(c)%2 else x.lower()) for x in T)
'sOmE sAmPlE tExT hErE'
