How to create changing variables within a formatted string?

Question

Sorry for the title it's hard to explain. This code is pretty self-explanatory for what I'm trying to accomplish. Thanks for any help!

handtype = ""
hand_format = 'Handtype: %s' % (handtype)
if y:
    handtype = "Straight"
    hand = hand_format

hand

Desired Output = 'Handtype: Straight'

Not really sure if this helps but you can look into Dictionary implementations programiz.com/python-programming/dictionary — HARSH MITTAL

A simple approach would be to access the value by defining a function instead. Something like this:-

handtype = ""
hand_format = lambda : f"Handtype : {handtype}"
if y:
    handtype = "Straight"
    hand = hand_format()

hand

Whenever you will call hand_format, you will access the latest value.

The hand_format is created once, and by changing the handtype , it does not change.

Only the string format should be saved in the hand_format variable.

You have to do this :

handtype = ""
hand_format = 'Handtype: %s' 
if y:
    handtype = "Straight"
    hand = hand_format % (handtype)

hand

If we print hand

Handtype: Straight

This is exactly what I was trying to avoid doing. But perhaps there is no way around it. Thank you
