Split a string in Python and extract few fields from list

I recently started working with Python and I am trying to split a string in Python and then extract only fields from that list.

Below is my node string and it will always be of four words separated by /.

node = "/tt/pf/test/v1"

I am trying to split above string on / and then store test and v1 value from it in some variable -

Below is what I have tried -

node = "/tt/pf/test/v1"
a,b,c,d = node.split("/")
print c
print d

Below is the error I got -

ValueError: too many values to unpack

You're not taking into the account the empty string generated by the first / character:

node = "/tt/pf/test/v1"
node.split('/')
['', 'tt', 'pf', 'test', 'v1']

A quick fix can be this:

_,a,b,c,d = node.split("/")

or slice the split() result:

a,b,c,d = node.split("/")[1:]

node.split("/")

['', 'tt', 'pf', 'test', 'v1']

First one counts as an empty word. Try: skip,a,b,c,d = node.split("/")

This divides it into 5 values, not 4, because it includes the empty string before the / at the start.

node.split("/")
# ['', 'tt', 'pf', 'test', 'v1']

Try:

empty,a,b,c,d = node.split("/")
