#reversed() is used to reverse the order of elements of a str or a container
#you can't reverse a string and convert it back to a string using str()
a='redrum' ; b='ypareht deen I'
x=list(reversed(a))
y=list(reversed(b))
print(x) #yeilds ['m','u','r','d','e','r']
print(y) #yeilds['I',' ','n','e','e','d',' ','t','h','e','r','a','p','y']
#if we want a string version of the list, we can use the .join function
c=''.join(x) ; d=''.join(y)
print(c) #yeilds: murder
print(d) #yeilds: I need therapy
