问题 I am having a peculiar problem when writing zip files through to_csv. Using GZIP: df.to_csv(path_or_buf = 'sample.csv.gz', compression="gzip", index = None, sep = ",", header=True, encoding='utf-8-sig') gives a neat gzip file with name ' sample.csv.gz ' and inside it I get my csv ' sample.csv ' However, things change when using ZIP df.to_csv(path_or_buf = 'sample.csv.zip', compression="zip", index = None, sep = ",", header=True, encoding='utf-8-sig') gives a zip file with name ' sample.csv

问题 I am trying to automate Print Save Web Page as pdf in chrome. I have checked the webbrowser module, but it does not seem to be intended for this purpose. I explored wkhtmltopdf as an alternative but when downloading the file it seems to be infected by a virus.

问题 I want to use messaging library in my application to interact with rabbitmq. Can anyone please explain the differences between pika and kombu library? 回答1: Kombu and pika are two different python libraries that are fundamentally serving the same purpose: publishing and consuming messages to/from a message broker. Kombu has a higher level of abstraction than pika. Pika only supports AMQP 0.9.1 protocol while Kombu can support other transports (such as Redis). More generally, Kombu is more
