It does NOT give and error. But it also does not produce an output.

The script is made to do the following:

The script takes an input file of 4 tab-separated columns:

It then counts the unique values in Column 1 and the frequency of corresponding values in Column 4 (which contains 2 different tags: C and D).

The output is 3 tab-separated columns containing the unique values of column 1 and their corresponding frequency of values in Column 4: Column 2 has the frequency of the string in Column 1 that corresponds with Tag C and Column 3 has the frequency of the string in Column 1 that corresponds with Tag D.

Here is a sample of input:

algorithm-n like-1-resonator-n 8.1848 C algorithm-n produce-hull-n 7.9104 C algorithm-n like-1-resonator-n 8.1848 D algorithm-n produce-hull-n 7.9104 D anything-n about-1-Zulus-n 7.3731 C anything-n above-shortage-n 6.0142 C anything-n above-1-gig-n 5.8967 C anything-n above-1-magnification-n 7.8973 C anything-n after-1-memory-n 2.5866 C

Here is a sample of desired output:

algorithm-n 2 2 anything-n 5 0

The code that I have done is the following:

from collections import defaultdict, Counter def sortAndCount(opened_file): lemma_sense_freqs = defaultdict(Counter) for line in opened_file: lemma, _, _, senseCode = line.split() lemma_sense_freqs[lemma][senseCode] += 1 return lemma_sense_freqs def writeOutCsv(output_file, input_dict): with open(output_file, "wb") as outfile: for lemma in input_dict.keys(): for senseCode in input_dict[lemma].keys(): outstring = "\t".join([lemma, senseCode,\ str(input_dict[lemma][senseCode])]) outfile.write(outstring + "\n") #################### import os import glob folderPath = "Python_Counter" # declare here for input_file in glob.glob(os.path.join(folderPath, 'out_')): with open(input_file, "rb") as opened_file: lemma_sense_freqs = sortAndCount(input_file) output_file = "count_*.csv" writeOutCsv(output_file, lemma_sense_freqs)

My intuition is the problem is coming from the "glob" function.

But, as I said before: the code itself DOES NOT give me an error -- but it doesn't seem to produce an output either.

Can someone help?
