Find the letter with which words most often begin in A.P. Chekhov's story "Anna on the Neck."

Use the word frequency file words_freq.txt.
Write Python code that displays the most popular first letter and the number of words for it.
Hints
Most likely, you will look in the dictionary for the key with the maximum value. To make things easier, sort the dictionary. Sorting a dictionary by value is more difficult than a list of objects that can be compared directly. Pay attention to the key parameter of the sorted function. for this task , this code :
first_letters_freq = {}
splitters = [' ', '\t']


with open('words_freq.txt', 'r', encoding='UTF-8') as file:
lines = file.readlines()

for line in lines:
for splitter in splitters:
print(line, splitter)
print(line.strip().split())
word,count = line.strip().split(splitter)
print(word,count)
count = int(count)
first_letter = word[0].lower()
if first_letter in first_letters_freq:
first_letters_freq[first_letter] += count
else:
first_letters_freq[first_letter] = count


sorted_freq = sorted(first_letters_freq.items(), key=lambda x: x[1], reverse=True)

print(sorted_freq)
most_common_letter, freq = sorted_freq[0]
print(sorted_freq)
print(f'Наиболее популярная первая буква: {most_common_letter.upper()}')
print(f'Количество слов на эту букву: {freq}')            but it is not showing the words of the text. here add the code which shows the words of the text which most frequent appears
