the ropes

I'm a little stuck... Click here to teach me more about this clue!

'there's zero pressure to absorb practical knowhow' is the definition.
I can't tell whether this defines the answer.

'there's zero pressure to absorb' is the wordplay.
'zero' becomes 'O' (O resembles 0).
'pressure' becomes 'p' (abbreviation).
'to absorb' indicates putting letters inside.
'o'+'p'='op'
'theres' enclosing 'op' is 'THE ROPES'.

Can you help me to learn more?

(Another definition for the ropes that I've seen is " way of operating".)
