Python error : 'tuple' object has no attribute 'upper'

Question

I wanna make word count and list how many times word counted. But

 f = open("Les.Miserable.txt", 'r')

 words = f.read().split()
 words.sort()
 wordCount = ()

 for i in range(len(words)):
     words[i] = words[i].replace(".", ""), (",", ""), ("/", ""), ("?", ""), ("!", "")
     words[i] = words[i].upper()
     if words[i] not in wordCount:
         wordCount[words[i]] = 1 
     else:
         wordCount[words[i]] += 1

i can see error message 'tuple' object has no attribute 'upper' in

words[i] = words[i].upper()

here

and also error message 'tuple' object does not support item assignment in

wordCountint[words[i]] = 1

Please let me know know what is the problem

you can add print before statement to find out type of object. — Zaaferani

i find out what type it is by print(type(words[i])) = class str , but it doesn't work — JUPPIN

If you print the value of words[i] after your attempted character replacements you will see that it is set to a tuple, e.g.

('word', (',', ''), ('/', ''), ('?', ''), ('!', ''))

So the line that tries to remove unwanted punctuation actually creates a tuple because that's what the comma separated items are, i.e.

words[i].replace(".", ""), (",", ""), ("/", ""), ("?", ""), ("!", "")

is actually a tuple consisting of words[i].replace(".", "") followed by (",", ""), etc.

You might have meant to chain a whole lot of replace operations together, but that would need to look like this:

words[i].replace(".", "").replace(",", "").replace("/", "").replace("?", "").replace("!", "")

But that is pretty ugly, and it's restricted to just a few punctuation symbols. str.translate() is better:

words[i] = words[i].translate(None, '.,/?!')

or, if you want to get rid of all punctuation you can use string.punctuation:

import string
words[i] = words[i].translate(None, string.punctuation)

Or, if you are using Python 3:

import string
words[i] = words[i].({ord(c):None for c in string.punctuation})

There are other problems in your code, but see if you can correct this first issue first.

I changed to what you commented but there is another error on wordCount[words[i]] = 1 . Error says 'tuple' object does not support item assignment. could i know what is wrong? and i questioned wrong like wordCountint[words[i]] = 1 but wordCount[words[i]] = 1 is right

in this line:

words[i] = words[i].replace(".", ""), (",", ""), ("/", ""), ("?", ""), ("!", "")

you assign tuple into words[i]. i guess you want to replace several character and that you mean to do this:

words[i] = words[i].replace(".", "").replace(",", "").replace("/", "").replace("?", "").replace("!", "")

several values with comma between them are tuple. 1,5,6 is the same as (1,5,6) so
words[i].replace(".", ""), (",", ""), ("/", ""), ("?", ""), ("!", "")
is the same as
(words[i].replace(".", ""), (",", ""), ("/", ""), ("?", ""), ("!", ""))

in addition, you can't assign into tuple, therefore. the line

wordCount[words[i]] = 1

can throw an exception, you need to change wordCountint to a dict (when you create it):

wordCount = {}

Thank you for answering. I have changed it but it still error on here wordCount[words[i]] = 1 TypeError: 'tuple' object does not support item assignment

I replaced like this words[i] = words[i].replace(".", "").replace(",", "").replace("/", "").replace("?", "").replace("!", "") but there is another error on if words[i] not in wordCount: wordCount[words[i]] = 1 and error says 'tuple' object does not support item assignment

Elisha Over a year ago

change wordCount = () to wordCount = [] (you can't assign into tuple, however you can into list)

JUPPIN Over a year ago

i changed to [] and error says : list indices must be integers, not str

Elisha Over a year ago

oops, you are right, I meant dictionary. change to {}

words[i] = words[i].replace(".", ""), (",", ""), ("/", ""), ("?", ""), ("!", "")

The above code is making words a tuple. And you cannot perform operations like upper() on the tuple. Hence, the error. I think, what you want to do is

words[i] = words[i].replace(".", "").replace(",", "").replace("/", "").replace("?", "").replace("!", "")

Also, you have declare wordCount = () as tuple. You won't be able to edit wordCount because of this, and this will lead to an error. It should be a dictionary : wordCount = {}

The entire program should look like:

f = open("Les.Miserable.txt", 'r')

words = f.read().split()
words.sort()
wordCount = {}

for i in range(len(words)):
    words[i] = words[i].replace(".", "").replace(",", "").replace("/", "").replace("?", "").replace("!", "")
    words[i] = words[i].upper()
    if words[i] not in wordCount:
        wordCount[words[i]] = 1
    else:
        wordCount[words[i]] += 1
sorted_wordCount = sorted(wordCount.items(), key=operator.itemgetter(1), reverse=True)
print sorted_wordCount

What is wordCountint[words[i]]? I think the int is wrongly placed there.

It would be easy for us to help you, if you publish a small snapshot of Les.Miserable.txt

Les miserable strats like this Chapter one Jean Valjean One evening in October 1815, an hour before sunset, a man with a long beard and dusty, torn clothes walked into the town of Digne. He was in his late forties, of medium height, broad-shouldered and strong. A leather cap half-hid his face, which was sunburnt and shining with sweat. His rough yellow shirt was unbuttoned, revealing a hairy chest. On his back was a heavy soldier's bag, and in his hand was a large wooden stick. it is just simple text file

You have declared wordCount = () on top, which is a tuple. Hence, the error.
