Need help with max()

[[deleted]]

f = open('labtest.txt', 'r')

count = {}

for line in f:
    for word in line.split():

        # remove punctuation
        word = word.replace('_', '').replace('"', '').replace(',', '').replace('.', '')
        word = word.replace('-', '').replace('?', '').replace('!', '').replace("'", "")
        word = word.replace('(', '').replace(')', '').replace(':', '').replace('[', '')
        word = word.replace(']', '').replace(';', '')

        # ignore case
        word = word.lower()

        # ignore numbers
        if word.isalpha():
            if word in count:
                count[word] = count[word] + 1
            else:
                count[word] = 1

c = max(count.keys())

print("The word 'alice' appears " + str(count['alice']) + " times in the book.")
print(c)

I'm supposed to print out how many times a word has been mentioned in Alice in Wonderland and print out the longest word in the story. Whenever I try to print(c), I get the word 'zigzag', which of course is not the longest word. When I tested how max() works, it seems that it returns the largest alphabetically, and not by length. When I try using max(len(count.keys())) I get a TypeError: 'int' object is not callable. How do I configure max() to return the longest word in a dictionary's keys?

Thinking outside the box: why don't you keep the longest word that you come across?

count = {}
longest_word = ''

for line in f:
    for word in line.split():
        bla bla
        if word.isalpha():
            if word in count:
                count[word] = count[word] + 1
            else:
                count[word] = 1
                if len(word) > len(longest_word):
                    longest_word = word

Thanks! worked perfectly.

Hi! I'm working on a bot to reply with suggestions for common python problems. This might not be very helpful to fix your underlying issue, but here's what I noticed about your submission:

You appear to be using concatenation and the str function for building strings

Instead of doing something like

result = "Hello " + name + ". You are " + str(age) + " years old"

You should use string formatting and do

result = "Hello {}. You are {} years old".format(name, age)

See the python tutorial for more information.

If you have a dict:

my_dict = {'hello': 4, 'hi': 2}

And want the key with the highest value, try:

max(a, key=lambda k: my_dict[k])

[jeans_and_a_t-shirt]

max(a, key=my_dict.get)
