# define an example of string s s = "Python" # get the length of the string s n = len(s) # get the first character of the string s first = s[0] last = s[n-1] # extract the substring obtained from s ignoring the first and the last character s1 = s[1:n-1] # construct a new string by changing the first and last character s2 = last + s1 + first print(s2) # output: 'nythoP' |
