In this HackerRank Mutation problem solution in python, We have seen that lists are mutable (they can be changed), and tuples are immutable (they cannot be changed). Read a given string, change the character at a given index and then print the modified string.
Problem solution in Python 2 programming.
S=raw_input() i,c=map(str,raw_input().split()) i=int(i) print S[:i] + c + S[i+1:]
Problem solution in Python 3 programming.
string = input() line = input().split() i, c = int(line[0]), line[1] print(string[:i] + c + string[i+1:])
Problem solution in PyPy programming.
# Enter your code here. Read input from STDIN. Print output to STDOUT S=raw_input() n,a=raw_input().split() l=list(S) l[int(n)]=a print ''.join(l)
Problem solution in PyPy3 programming.
#def mutate_string(string, position, character) #print(input()) string=list(input()) [a,b]=(input().split()) #print ([a,b]) #print(string[int(a)]) #print(i) #print(rep) #string = string[:i] + str(b) + string[(i+1):] string[int(a)]= str(b) string="".join(string) print (string) #return
