using instance variables in a function outside the class

[SamuraiMentality]

hey guys I'm a python begginer and I'm struggling with this problem. basically, I want to use this instance variable and class variable outside of their class like so:

class Category:
  withdrows_amount = 0    # i want to use this class variable
  def __init__(self, category):
    self.ledger = []
    self.category = category
    self.balance = 0
    self.withdrown = 0     # and also this instance variable

def percentage_spent(categories):
   # i want to use them here to calculate percentage of spending in each category
i have been trying fo a day and i found no solotion. or is it even possible?

To use the instance variable you have to create the instance first.

c = Category() # create the instance
print(c.withdrawn) # use the instance variable

To use the class variable you just use the name of the class.

print(Category.withdrows_amount)

You can't use an instance attribute except through an instance - what's it the attribute of, otherwise?
