Question

Write a user defined function in Python named Puzzle (W, N) which takes the argument W as an English word and N as an integer and returns the string where every N^th alphabet of the word W is replaced with an underscore ("_").

For example: if W contains the word "TELEVISION" and N is 3, then the function should return the string "TE_EV_SI_N". Likewise for the word "TELEVISION" if N is 4, then the function should return "TEL_VIS_ON".

Answer 1

def puzzle(w,n): 
      mystr=""
      for i in range(0,len(w)): 
            if (i+1)%n==0: 
                  mystr += "_" 
            else: 
                  mystr + = w[i] 
      print(mystr) 
      return mystr
