File not found error, even though file was found

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"):
            f= open(file)
            lines = f.readlines()
            tokens = [line.split()[3] for line in lines if line.strip() 
and not line.startswith("#")]
    print(tokens)

I get the following error:

Traceback (most recent call last): File "text_statistics.py", line 28, in corpus_reading_pos(corpus_name, option) File "text_statistics.py", line 13, in corpus_reading_pos f= open(file) FileNotFoundError: [Errno 2] No such file or directory: 'abc_0001.v4_gold_conll'

As you can see, the file was, in fact, located, but then when I try to open the file, it... can't find it?

Edit: using this updated code, it stops after reading 7 files, but there are 172 files.

def corpus_reading_token_count(corpus_name, option="token"):
    for root, dirs, files in os.walk(corpus_name):
        tokens = []
        file_count = 0
        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("#")]
                    file_count += 1
    print(tokens)
    print("File count:", file_count)

file is just the file without the directory, which is root in your code. Try this:

f = open(os.path.join(root, file)))

Also, you should better use with to open the file, and not use file as a variable name, shadowing the builtin type. Also, judging from your comment, you should probably extend the list of tokens (use += instead of =):

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

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)
