Python Lowercase and Uppercase String

Question

Is there a way to convert a string to a sequence of uppercase and lowercase letters?

For example, "Kilometers" → "KiLoMeTeRs".

Answer 1

a = 'Kilometers'

print(''.join([char.upper() if i%2==0 else char.lower() for i, char in enumerate(a)]))

result = 'KiLoMeTeRs'
