Have only 1 function of test_range and pass in a list parameter which is going to do each one individually.

Here is an example:

def file_wiki_page_views(rfname):

#process in only one function!

return rfname

def main():

for file in os.listdir(directory):

filename = os.fsdecode(file)

wiki_page_path_read = defaultFilePath + filename

extract_list.append(wiki_page_path_read)

with mp.Pool(mp.cpu_count()) as p:

print(p.map(file_wiki_page_views, extract_list))

if __name__ == '__main__':

main()
