File not found error, even though file was found

Question

Using the following bit of code:

for root, dirs, files in os.walk(corpus_name):
    for file in files:
        if file.endswith(\".v4_gold_conll\"):
                     


        

Answer 1

You'll have to join the root with the filename.

for root, dirs, files in os.walk(corpus_name):
    for file in files:
        if file.endswith(".v4_gold_conll"):
            with open(os.path.join(root, file)) as f:
            tokens = [
                line.split()[3]
                for line in f
                if line.strip() and not line.startswith("#")
            ]
            print(tokens)
