I'm trying to put some code into a function but I get an Unbound Local Error - I sort of understand why, I just don't know how to fix it.
edit: specifically I was told not to use global because global "is a bad idea". Surely there must be another way?
In the overall code I have multiple variables which need to be altered by user_input and those altered values then need to be passed through one or more different functions (repeatedly (with new values) until a certain conclusion is drawn).
How can I use the variables in multiple functions (cleanly)? If I define them in one function then they're only available there, right? And I can't alter their values from/to elsewhere?
Thank you for any help.
This is a sketch of the code I want to put in a function:
#variables that need to be used (and altered) within multiple functions
Var1 = #a_number
Var2 = #a_number
Var3 = #a_number
def a_function(): #created Unbound Local Error
output() #prints original vars
while True:
inp = float(input("Enter a number: "))
Var1 += inp
Var2 -= inp
Var3 *= inp
output() #prints new values for vars
if/elif/else....
#when Vars are a certain number new calculations are done
#on them. Regardless, there is always only one output of
# the 3 Vars
#some Var vals trigger certain functs which print those new value
#or functions which may even manipulate the values further
