ResourceWarning: unclosed file <_io.BufferedWriter

[mingdh]

There is warning from python,
newspaper/utils.py:238: ResourceWarning: unclosed file <_io.BufferedWriter name='/var/****/.newspaper_scraper/feed_category_cache/4493fab35f9369455967c00969619b802f1a2559'>
pickle.dump(result, open(filepath, "wb"))

it seems that you open file, but not closed.
Is it ok to change the following code?

... and save the cached object for next time

with open(filePath,'wb') as f:
pickle.dump(result, f)
