Proxy setting parameters need to be added about gtts

Hi @zwssunny!

So this should be better documented, but it's possible to set proxy settings with environment variables via the way requests handles it. See here, specifically that part:

When the proxies configuration is not overridden per request as shown above, Requests relies on the proxy configuration defined by standard environment variables http_proxy, https_proxy, no_proxy, and all_proxy. Uppercase variants of these variables are also supported. You can therefore set them to configure Requests (only set the ones relevant to your needs):

$ export HTTP_PROXY="http://10.10.1.10:3128"
$ export HTTPS_PROXY="http://10.10.1.10:1080"
$ export ALL_PROXY="socks5://10.10.1.10:3434"

$ python
>>> import requests
>>> requests.get('http://example.org')
