# %% Import of e.g. numpy placed here if needed

# import numpy as np

# %% Defintion of class Formula_1:

class Formula_1(object):
    
    def __init__(self, c0, c1):
        self.c0 = c0
        self.c1 = c1
        
    def output(self, x):
        c0 = self.c0
        c1 = self.c1
        y = c1*x + c0
        return y
        
    def rate(self):
        r = self.c1
        return r

# %% Application of class Formula_1:

# Defining variables used in calling instance of class:
k0 = 0
k1 = 1
x = 5

# Creating instance here named F1:
F1 = Formula_1(k0, k1)

# Calling method named output of F1:
print('Output value y1:', F1.output(x))

# Calling method named rate of F1:
print('Calculating rate coeff of formula:', F1.rate())

# Showing data attribute c0 of F1:
print('Data attribute c0: ', F1.c0)

# Showing type of F1:
print('Instance type of F1: ', type(F1))
