I am new to python and am trying to find the largest word in the alice_in_worderland.txt. I think I have a good system set up ("See Below"), but my output is returning a "word" with dashes connecting multiple words. Is there someway to remove the dashes in the input of the file? For the text file visit here

sample from text file:

That's very important,' the King said, turning to the jury. They were just beginning to write this down on their slates, when the White Rabbit interrupted: UNimportant, your Majesty means, of course,' he said in a very respectful tone, but frowning and making faces at him as he spoke. " UNimportant, of course, I meant,' the King hastily said, and went on to himself in an undertone, important--unimportant-- unimportant--important--' as if he were trying which word sounded best."

code:

    #String input
    with open("alice_in_wonderland.txt", "r") as myfile:
        string=myfile.read().replace('\n','')
    #initialize list
    my_list = []
    #Split words into list
    for word in string.split(' '):
        my_list.append(word)
    #initialize list
    uniqueWords = []
    #Fill in new list with unique words to shorten final printout
    for i in my_list:
        if not i in uniqueWords:
            uniqueWords.append(i)
    #Legnth of longest word
    count = 0
    #Longest word place holder
    longest = []
    for word in uniqueWords:
        if len(word)>count:
            longest = word
            count = len(longest)
        print longest

  • Can you provide a sample of input (not everyone wants to follow a link to get your data) and output that's required? Describe how it differs from what you've got now etc... Commented Aug 16, 2014 at 23:02

  • This is a small subset with the unusual quote. I don't know if I can count the dashed phase as the longest word though, so any thoughts on how to remove them from the input? Maybe something like .replace('\n','\-','')? Commented Aug 16, 2014 at 23:10

Reset to default

>>> import nltk # pip install nltk
>>> nltk.download('gutenberg')
>>> words = nltk.corpus.gutenberg.words('carroll-alice.txt')
>>> max(words, key=len) # find the longest word

Seems we get the same answer then
+1 from me for serious usage of word usage - NLTK is the way to go
thumbs up! I didn't know about nltk

Here's one way using re and mmap:

import re
import mmap

with open('your alice in wonderland file') as fin:
    mf = mmap.mmap(fin.fileno(), 0, access=mmap.ACCESS_READ)
    words = re.finditer('\w+', mf)
    print max((word.group() for word in words), key=len)

# disappointment

Far more efficient than loading the file to physical memory.

Use str.replace to replace the dashes with spaces (or whatever you want). To do this, simply add another call to replace after the first call on line 3:

string=myfile.read().replace('\n','').replace('-', ' ')
