Example of how to read a compressed file::
import gzip
- f = gzip.open('file.txt.gz', 'rb')
- file_content = f.read()
- f.close()
+ with gzip.open('file.txt.gz', 'rb') as f:
+ file_content = f.read()
Example of how to create a compressed GZIP file::
import gzip
content = "Lots of content here"
- f = gzip.open('file.txt.gz', 'wb')
- f.write(content)
- f.close()
+ with gzip.open('file.txt.gz', 'wb') as f:
+ f.write(content)
Example of how to GZIP compress an existing file::
import gzip
- f_in = open('file.txt', 'rb')
- f_out = gzip.open('file.txt.gz', 'wb')
- f_out.writelines(f_in)
- f_out.close()
- f_in.close()
+ import shutil
+ with open('file.txt', 'rb') as f_in, gzip.open('file.txt.gz', 'wb') as f_out:
+ shutil.copyfileobj(f_in, f_out)
