# Very simple HTTPS client example:

# - Connects to a server.

# - Upgrades the connection to a TLS connection.

# - Sends a HTTP request.

# - Reads the result.

#

# This example works in both MicroPython and CPython.

#

# To implement an HTTPS client using less code, use mip to install the requests package:

# https://github.com/micropython/micropython-lib/tree/master/python-ecosys/requests
