Python Program to Create a Dictionary with Key as First Character and Value as Words Starting with that Character

When it is required to create a dictionary with the key as the first character and the associated value as the word which is the starting of that character, the s’plit’ method, a dictionary and simple ‘if’ condition is used.

Example

Below is a demonstration for the same −

 Live Demo

my_string=input("Enter the string :") split_string = my_string.split() my_dict={} for elem in split_string:    if(elem[0] not in my_dict.keys()):       my_dict[elem[0]]=[]       my_dict[elem[0]].append(elem)    else:       if(elem not in my_dict[elem[0]]):          my_dict[elem[0]].append(elem) print("The dictionary created is") for k,v in my_dict.items():    print(k,":",v)

Output

Enter the string :Hey Jane, how are you The dictionary created is H : ['Hey'] J : ['Jane,'] h : ['how'] a : ['are'] y : ['you']

Explanation

• The string is taken as input from the user.
• This is assigned to a variable.
• This string is split, and assigned to a variable.
• An empty dictionary is created.
• The variable is iterated over, and if the first element is not present as a key in the dictionary, its element is assigned an empty list.
• Now, the elment is added to the dictionary.
• Otherwise, the element is directly appended to the dictionary.
• This dictionary is created, and is displayed on the console.
