Removing characters from the left side of a Python string?

Question

How would I go about removing characters from the left side of a Python string? Example:

string = "Devicename MA:CA:DD:RE:SS"

What should I do to make a new string of just the MAC Address?

Do you know how slicing works? – miradulo Apr 22 '16 at 14:08 — miradulo, Apr 22 '16 at 14:08

You can do different things:

string.split(' ')[1]

or

string[11:]

or

string[-14:]

both yielding

'MA:CA:DD:RE:SS'

The last option is the closest to what you want I suppose. It takes the leftmost 14 characters from the string.

Assuming that the string always has the format:

Devicename<space>MAC Address

You can do this by simply splitting the string on the space and taking the second element in the resulting list.

>>> string = "Devicename MA:CA:DD:RE:SS"
>>> string.split()[1]
'MA:CA:DD:RE:SS'

One note - I assume you know that is not a valid MAC address, correct?
