The rgb() method is incomplete. | |
Complete the method so that passing in RGB decimal values will result in a hexadecimal representation being returned. | |
The valid decimal values for RGB are 0 - 255. Any (r,g,b) argument values that fall out of that range should be rounded to the closest valid value. | |

return ("{:02X}" * 3).format(round(r), round(g), round(b)) |

When hosting our web applications, we often have one public IP
address (i.e., an IP address visible to the outside world)
using which we want to host multiple web apps. For example, one
may wants to host three different web apps respectively for
example1.com
, example2.com
, and example1.com/images
on
the same machine using a single IP address.
How can we do that? Well, the good news is Internet browsers
