Hi there, I have been following your Hacherrank exercise videos and have started to be able to solve them on my own. Your explanations have helped me a lot, now I know how to tackle the challenges. thanks!

Btw, I find the structure of commands in Python very confusing, sometimes they are written as "sum(value)" or "my_list.sort()". The variable that is making the change can be inside the parenthesis and others before the command and with empty parenthesis. Is there any reason for it to be like it?

I have one question, if we are using swapcase() method that can directly convert uppercase to lower and vice versa then what's the point to use for loop here??

can we use like this??

def swap_case(s):
return

if __name__ == '__main__':
s = input("Enter the String: ")
result = s.swapcase()
print("\nString after swap:", result)
print("\nString after reverse:", result[::-1])
