String traversal will take place from left to right, not from right to left. Solution: def   count_substring ( string ,   sub_string ):      count  =  0      for   i   in   range ( len ( string )):          if   string [ i :] . startswith ( sub_string ):                  count  +=  1      return   count if  __ name__  ==  '__main__' :      string  =  input () . strip ()      sub_string  =  input () . strip ()           count  =  count_substring ( string ,   sub_string )      print ( count )
