A note about proxies

If you are in a corporate environment, you probably connect to the Internet through another computer called a 'proxy'. You will need the URL of this proxy; it might look like https://proxy.my-company.net:8080. Then use it in your Python environment like this:

proxies  = {'https': 'https://proxy.my-company.net:8080'}
r = requests.get(url, proxies=proxies)

Each time you use requests.get() you will need to pass the proxies dictionary in this way.

Getting SSLCertVerificationError or similar

If you get some variant of SSLError, SSLCertVerificationError, CERTIFICATE_VERIFY_FAILED or certificate verify failed: unable to get local issuer certificate, then you need to tell requests where to find your certificates. On Linux, they are usually in /etc/ssl/certs. For example, this sort of thing might work:

verify = '/etc/ssl/certs/ca-bundle.crt'
r = requests.get(url, verify=verify)

On Windows you need to export your CA certs from your registry to a file and point requests to that.
