Code erros

Question

#I am confused on the errors I am running into. I Would be thankfull if someone helped me out.
global p1,v1,p2,v2
import cmath
import math
def getinput():
p1 = input("what is the initial pressure value?")
v1 = input("what is the initial volume?")
p2 = input("what is the final pressure?")
v2 = input("what is the final volume?")
return(getinput()
import math
import cmath
global p1,v1,p2,v2
def equation(getinput):
equation == (p1*v1 / p2*v2)
print(equation)
return(getinput())

def none(equation):
if p1 == "none":
equation = p1 = (v1)/(p2*v2)
else:
equation = (p1*v1)/(p2*v2)
if v1 == "none":
equation = v1 = (p1)/(p2*v2)
else:
equation = (p1*v1)/(p2*v2)
if p2 == "none":
equation = p2 = (p1*v1)/(v2)
else:
equation = (p1*v1)/(p2*v2)
if v2 == "none":
equation = v2 = (p1*v1)/(p2)
else:
equation = (p1*v1)/(p2*v2)
print(equation)

Answer 1

Can you post the error you are getting? :)

It looks like there is a lot of duplicat code in there.

Answer 2

One error i'm getting is a syntax error in line 13. When I use my code in another programing environment, such as jupyter notebook, I get no errors. The only issue I run into is when I run the equation function, the answer is always 0.

Answer 3

You seem to be using return outside of a function. And getinput() doesn't return anything explicitly, so it'll just return None. Your indentation also seems to be wrong. You don't need to import math etc. several times. global outside of a function doesn't make sense. Please upload your code to the code playground and post a link
