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

Dictionaries are versatile data structures in Python that allow you to map keys to corresponding values. This program demonstrates how to create a Python program that constructs a dictionary where the keys are the first characters of words, and the values are lists of words that start with the corresponding character.

Problem Statement

Write a Python program that takes a list of words as input and constructs a dictionary with keys as the first characters of words and values as lists of words that start with the corresponding character.

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

def create_char_dict(word_list):
    char_dict = {}

    for word in word_list:
        if word[0] in char_dict:
            char_dict[word[0]].append(word)
        else:
            char_dict[word[0]] = [word]

    return char_dict

# Input
words = input("Enter a list of words (comma-separated): ").split(',')

# Creating the dictionary
result_dict = create_char_dict(words)

# Output
print("Dictionary with words grouped by first character:")
for key, value in result_dict.items():
    print(f"'{key}': {value}")
