To convert a compressed CSV file (.csv.gz
) to a CSV file (.csv
) and read it in your Python shell, use the gzip.open(filename, 'rt', newline='')
function call to open the gzipped file, the file.read()
function to read its contents, and the file.write()
function to write the CSV in a normal (unzipped) file.
The gzip.open()
function has the following arguments:
filename
specifies the name of the GZipped file.'rt'
opens the file in reading ('r'
) text ('t'
) mode (not binary mode)newline=''
prevents adding a blank line in some OS environments.
π You don’t need to install the gzip
module because it’s already part of Python’s standard library. π
Here’s the code to read and load a GZipped CSV to Python:
import gzip with gzip.open('my_file.csv.gz', 'rt', newline='') as csv_file: csv_data = csv_file.read() with open('my_file.csv', 'wt') as out_file: out_file.write(csv_data)
π‘ Note: Depending on the .csv.gz file’s encoding, you may want to pass encoding='utf-8'
, 'latin-1'
, utf-16'
, or your specific file encoding into gzip.open()
to prevent any encoding/decoding errors.
