I\'m new with python and scrapy. I\'m tring to follow the Scrapy tutorial but I don\'t understand the logic of the storage step.
scrapy crawl spidername -o items
--set
Arguments provided by the command line are the ones that take precedence, overriding any other options.
You can explicitly override one (or more) settings using the -s (or --set) command line option.
Example:
scrapy crawl myspider -s LOG_FILE=scrapy.log
sets the LOG_FILE settings value to `scrapy.log`
-o
Specifies the output filename and extension WHERE you will write the scraped data to
Examples:
scrapy crawl quotes -o items.csv
scrapy crawl quotes -o items.json
scrapy crawl quotes -o items.xml
-t
Specifies the serialisation format or HOW the items are written
