``````I am asking for input from a data file that only has 3 numbers and its saying theres too many to unpack... I already checked for whitespace and extra lines or whatever...

CODE:

import math

def __init__(self, x, y, z):
self.__a = x
self.__b = y
self.__c = z
def GetCoeff(self):
self.__a, self.__b, self.__c = input()
return self.__a, self.__b, self.__c
def checkRoots(self):
if (self.__b**2 - (4 * self.__a * self.__b)) == 0:
amountOfRoots = "1 Root"
elif (self.__b**2 - (4 * self.__a * self.__b)) > 0:
amountOfRoots = "2 Roots"
elif (self.__b**2 - (4 * self.__a * self.__b)) < 0:
amountOfRoots = "No Real Roots"
else:
amountOfRoots = "Error"
return amountOfRoots
def solveRoots(self):
root1 = (-self.__b + math.sqrt(self.__b**2-(4*self.__a*self.__c)))/2*self.__a
root2 = (-self.__b - math.sqrt(self.__b**2-(4*self.__a*self.__c)))/2*self.__a
return root1, root2

def main():
print(format("Coefficients", '>17'), format("# of Roots", '>16'), format("Roots", '>15'))
print("=======================================================")
QE.GetCoeff()
QE.checkRoots()
QE.solveRoots()
main()

INPUT FILE:
1,-8,16

COMMAND TO EXECUTE:
python file.py <file.data
``````

Is this something related to OpenERP?

This is not the right place to ask for code that is not related to OpenERP, you can try on Stackoverflow
