How do I properly read a gzip file in Python?

I am trying to run the following code to read a gzip file:

import gzip
f = gzip.open('Onlyfinnaly.log.gz', 'rb')
file_content = f.read()
print(file_content)

However, I don’t get any output on the screen. What might be the issue, and how can I correctly read a gzip file in Python?

To properly read a gzip file in Python, try gzipping some data first using the gzip library as follows:

import gzip
content = "Lots of content here"
f = gzip.open('Onlyfinnaly.log.gz', 'wb')
f.write(content.encode()) # Ensure content is encoded to bytes
f.close()

Then, you can read the file like this:

import gzip
with gzip.open('Onlyfinnaly.log.gz', 'rb') as f:
file_content = f.read()
print(file_content.decode()) # Decode from bytes to string

This method worked for me, as sometimes the gzip library struggles with certain files.

You can try using the with statement to automatically close the file, as shown in the example above, which ensures proper handling of file opening and closing.
