Python代码问题：误将高频单词识别为最长单词

Hey there! Let's fix that bug in your report_stat function right away. The issue is clear: you're currently grabbing the most frequent word instead of the longest one, and it all boils down to one line of code.

What Went Wrong #

This line is the root cause:

max_word = max(word_dict, key = word_dict.get)

When you use key=word_dict.get, Python uses the value of each dictionary entry (the word's occurrence count) to find the maximum. That's why you're getting "the"—it's the most common word in your text, not the longest by character length.

Corrected Function #

Here's the fixed version, with the critical change highlighted:

def report_stat(word_dict):
    # Changed key to len() to compare word lengths, not occurrence counts
    max_word = max(word_dict, key=len)
    print('Longest word is:', max_word)
    
    # getting sorted list of word dict by value and printing 5 most common
    print('Five most common words are:')
    counter = 1
    for each_list in sorted(word_dict.items(), key=lambda x: x[1], reverse=True):
        # printing the 5 most commonly used words
        if counter > 5:
            break
        print(each_list[0], each_list[1])
        counter += 1
    
    # opening the file out.txt in write mode
    # and writing word and their count sorted alphabetically
    with open('out.txt', 'w') as fp:
        for each_word in sorted(word_dict):
            print(each_word, word_dict[each_word], file=fp)

Extra: Handling Ties for Longest Word #

If your text has multiple words with the same maximum length (like "antidisestablishmentarianism" and "floccinaucinihilipilification"), the above code will only return the first one it encounters. To list all longest words instead, replace the longest word section with this:

# Calculate the maximum word length first
max_length = max(len(word) for word in word_dict)
# Collect all words that match this length
longest_words = [word for word in word_dict if len(word) == max_length]
# Print all longest words
print('Longest word(s) are:', ', '.join(longest_words))

This way, you won't miss any words that share the title of longest.

Test It Out #

With this fix, running your code on pride.txt will now output the actual longest word in the text (like "unhappiness" or another lengthy term) instead of "the".
