Python: Counting words from a directory of txt files and writing word counts to a separate txt file

New to Python and I’m trying to count the words in a directory of text files and write the output to a separate text file. However, I want to specify conditions. So if word count is > 0 is would like to write the count and file path to one file and if the count is == 0. I would like to write the count and file path to a separate file. Below is my code so far. I think I’m close, but I’m hung up on how to do the conditions and separate files. Thanks.

import sys
import os
from collections import Counter
import glob

stdoutOrigin=sys.stdout 
sys.stdout = open("log.txt", "w")
              
def count_words_in_dir(dirpath, words, action=None):
    for filepath in glob.iglob(os.path.join("path", '*.txt')):
        with open(filepath) as f:
            data = f.read()
            for key,val in words.items():
            #print("key is " + key + "n")
                ct = data.count(key)
                words[key] = ct
            if action:
                 action(filepath, words)
            
                
                


def print_summary(filepath, words):
    for key,val in sorted(words.items()):
        print(filepath)
        if val > 0:
            print('{0}:t{1}'.format(
            key,
            val))
        







filepath = sys.argv[1]
keys = ["x", "y"]
words = dict.fromkeys(keys,0)

count_words_in_dir(filepath, words, action=print_summary)

sys.stdout.close()
sys.stdout=stdoutOrigin

Answer

I would strongly urge you to not repurpose stdout for writing data to a file as part of the normal course of your program. I also wonder how you can ever have a word “count < 0”. I assume you meant “count == 0”.

The main problem that your code has is in this line:

for filepath in glob.iglob(os.path.join("path", '*.txt')):

The string constant "path" I’m pretty sure doesn’t belong there. I think you want filepath there instead. I would think that this problem would prevent your code from working at all.

Here’s a version of your code where I fixed these issues and added the logic to write to two different output files based on the count:

import sys
import os
import glob

out1 = open("/tmp/so/seen.txt", "w")
out2 = open("/tmp/so/missing.txt", "w")

def count_words_in_dir(dirpath, words, action=None):
    for filepath in glob.iglob(os.path.join(dirpath, '*.txt')):
        with open(filepath) as f:
            data = f.read()
            for key, val in words.items():
                # print("key is " + key + "n")
                ct = data.count(key)
                words[key] = ct
            if action:
                action(filepath, words)


def print_summary(filepath, words):
    for key, val in sorted(words.items()):
        whichout = out1 if val > 0 else out2
        print(filepath, file=whichout)
        print('{0}: {1}'.format(key, val), file=whichout)

filepath = sys.argv[1]
keys = ["country", "friend", "turnip"]
words = dict.fromkeys(keys, 0)

count_words_in_dir(filepath, words, action=print_summary)

out1.close()
out2.close()

Result:

file seen.txt:

/Users/steve/tmp/so/dir/data2.txt
friend: 1
/Users/steve/tmp/so/dir/data.txt
country: 2
/Users/steve/tmp/so/dir/data.txt
friend: 1

file missing.txt:

/Users/steve/tmp/so/dir/data2.txt
country: 0
/Users/steve/tmp/so/dir/data2.txt
turnip: 0
/Users/steve/tmp/so/dir/data.txt
turnip: 0

(excuse me for using some search words that were a bit more interesting than yours)
