import requests
requests.get("http://myServer.com:4000")
:4000 means port 4000
#Well, I was missing the basis.
#When you perform an HTTP request, requests will try to connect on port 80.
#For HTTPS, requests will try to connect on port 443.
#If you want an exotic port such as 8080 this is how you should do it :
resp = requests.get(http://example.com:8080)
