Split List by First Character

Write a Python program to split a list based on the first character of a word.

Sample Input:

word_list = ['be','have','do','say','get','make','go','know','take','see','come','think',
     'look','want','give','use','find','tell','ask','work','seem','feel','leave','call']

Sample Solution:

Python Code:

# Import the 'groupby' function from the 'itertools' module and the 'itemgetter' function from the 'operator' module
from itertools import groupby
from operator import itemgetter

# Define a list 'word_list' containing words
word_list = ['be', 'have', 'do', 'say', 'get', 'make', 'go', 'know', 'take', 'see', 'come', 'think',
             'look', 'want', 'give', 'use', 'find', 'tell', 'ask', 'work', 'seem', 'feel', 'leave', 'call']

# Use 'groupby' to group and sort the words in 'word_list' based on the first letter of each word
# Iterate through the groups and print the first letter and the words starting with that letter
for letter, words in groupby(sorted(word_list), key=itemgetter(0)):
    print(letter)
    for word in words:
        print(word)

Sample Output:

a                                                                                                             
ask                                                                                                           
b                                                                                                             
be                                                                                                            
c                                                                                                             
call                                                                                                          
come                                                                                                          
d                                                                                                             
do        
-----
w                                                                                                             
want                                                                                                          
work
