def remove_odd_index_characters(my_str):
   new_string = ""
   i = 0
   while i < len(my_str):
      if (i % 2 == 1):
         i+= 1
         continue

      new_string += my_str[i]
      i+= 1
   return new_string

if __name__ == '__main__':
   my_string = "Hi there Will"

   my_string = remove_odd_index_characters(my_string)
   print("Characters from odd index have been removed")
   print("The remaining characters are : ")
   print(my_string)

Explanation

• A method named ‘remove_odd_index_characters’ is defined, that takes a string as parameter.

• An empty string is created.

• The string is iterated over, and the index of every element is divided by 2.

• If the remainder is not 0, then it is considered as an odd index, and it is deleted.

• In the main method, the method is called, and the string is defined.

• This string is passed as a parameter to the method.

• The output is displayed on the console.
