I have a small Python script that calculates the top 10 most frequent words, 10 most infrequent words and the total number of words in a .txt document. According to the assignment, a word is defined as 2 letters or more. I have the 10 most frequent and the 10 most infrequent words printing fine, however when I attempt to print the total number of words in the document it prints the total number of all the words, including the single letter words (such as "a"). How can I get the total number of words to calculate ONLY the words that have 2 letters or more?

Here is my script:

```from string import *
from collections import defaultdict
from operator import itemgetter
import re

number = 10
words = {}
total_words = 0
words_only = re.compile(r'^[a-z]{2,}\$')
counter = defaultdict(int)

"""Define function to count the total number of words"""
def count_words(s):
unique_words = split(s)
return len(unique_words)

"""Define words as 2 letters or more -- no single letter words such as "a" """
for word in words:
if len(word) >= 2:
counter[word] += 1

"""Open text document, strip it, then filter it"""

for line in txt_file:
total_words = total_words + count_words(line)
for word in line.strip().split():
word = word.strip(punctuation).lower()
if words_only.match(word):
counter[word] += 1

# Most Frequent Words
top_words = sorted(counter.iteritems(),
key=lambda(word, count): (-count, word))[:number]

print "Most Frequent Words: "

for word, frequency in top_words:
print "%s: %d" % (word, frequency)

# Least Frequent Words:
least_words = sorted(counter.iteritems(),
key=lambda (word, count): (count, word))[:number]

print " "
print "Least Frequent Words: "

for word, frequency in least_words:
print "%s: %d" % (word, frequency)

# Total Unique Words:
print " "
print "Total Number of Words: %s" % total_words
```

I am not an expert with Python, this is for a Python class I am currently taking. The neatness of my code and proper formatting count against me in this assignment, if possible can someone also tell me if the format of this code is considered "good practice"?

The list comprehension method:

```def countWords(s):
words = s.split()
return len([word for word in words if len(word)>=2])
```

The verbose method:

```def countWords(s):
words = s.split()
count = 0
for word in words:
if len(word) >= 2:
count += 1
return count
```

As an aside, kudos on using `defaultdict`, but I would go with `collections.Counter`:

```words = collections.Counter([word for line in open(filepath) for word in line.strip()])
words = dict((k,v) for k,v in words.iteritems if len(k)>=2)
mostFrequent = [w for w in words.most_common(10)]
leastFrequent = [w for w in words.most_common()[-10:]]
```

Hope this helps

How to Count Characters in MS Word, How do I count the number of words in a python file? Now, in order to make applying our regular expression easier, let's turn all the letters in our document into lower case letters, using the lower() function, as follows: text_string = document_text.read().lower() Let's write our regular expression that would return all the words with the number of characters in the range [3-15].

Count words simply uses split()

You should use the match_words regular expression here too

```def count_words(s):
unique_words = split(s)
return len(filter(lambda x: words_only.match(x):, unique_words))
```

Python String count(), How do you count the number of times a word appears in a string in python? I am trying to find a way to count two word sequence in a list of words using python. I converted the one word list into a list of two words.I then want to try to count the frequency of all the similar two word lists. I tried the counter function but it gives me an unhashable type: 'list'. An example of my code can be seen below:

PYTHON Count lines, words and characters in text file, This is an awesome Python exercise on counting. It involves working with text files, counting Duration: 2:36 Posted: Nov 21, 2015 To count total number of word present in the sentence in python, you have to ask from user to enter a sentence or string to count the total number of words as shown in the program given here. Simple Python script without the use of heavy text processing libraries to extract most common words from a corpus.

Personally, I think your code looks fine. I don't know if its "standard" python style, but it is easy to read. I'm pretty new to Python as well but here is my answer.

I'm assuming that your count_words(s) function is what calculates the total number of words. The problem you are having is that by just calling split; you are just separating the words by a space.

You only need to count the 2+ character of words, so in that function write a loop that counts only the number of words with 2+ characters in the unique_words list.

Counting Word Frequencies with Python, Counting the frequency of specific words in a list can provide illustrative data. Python has an easy way to count frequencies, but it requires the use of a new go through each word in the wordlist, and count the number of times that can be used to do the same thing as the for loop more economically. The algorithm to print the pattern using for loop in Python: We need to use two for loops to print patterns, i.e. nested loops. There is a typical structure to print any pattern, i.e. the number of rows and columns in the pattern. Outer loop tells us the number of rows used and the inner loop tells us the column used to print pattern.
