Question

The colours red, blue, and yellow are known as the primary colours because they cannot be made

by mixing other colours. When you mix two primary colours, you get one of following secondary

colour:

- Mix red and blue: purple

- Mix red and yellow: orange

- Mix blue and yellow: green

Write a function colour_mix that takes two strings as parameters as two primary colours and

returns the secondary colour. If the parameters are anything other than "red", "blue", or

"yellow", the function should return the string "Error". Save the function in a PyDev library

module named functions.py

Write a main program named t05.py that tests the function by asking the user to enter the names

of two primary colours to mix and displays the mixed colour.

A sample run:

Enter a first colour: red

Enter a second colour: blue

The mixed colour is purple.

Or

Enter a first colour: red

Enter a second colour: brown

The mixed colour is Error

• Test your program with 2 different data, other than the example.

• Copy the results to testing.txt.

PYTHON CODE:

#function definition
def colour_mix():
    #opening file 
    f=open("testing.txt","w")
    
    #taking inputs 
    a=input("Enter a first colour: ")
    b=input("Enter a second colour: ")
    
    #writing input colours to file
    f.write(f"First colour: {a}\nSecond colour: {b}\n\n")
    
    #condition for purple colour
    if (a=="blue" and b=="red") or (b=="blue" and a=="red"):
        print("The mixed colour is purple.")
        f.write("The mixed colour is purple.") #writing to file
        
    #condition for orange colour
    elif (a=="yellow" and b=="red") or (b=="yellow" and a=="red"):
        print("The mixed colour is orange.")
        f.write("The mixed colour is orange.")  #writing to file
        
    #condition for green colour
    elif (a=="yellow" and b=="blue") or (b=="yellow" and a=="blue"):
        print("The mixed colour is green.")
        f.write("The mixed colour is green.")  #writing to file
        
    #for wrong input
    else:
        print("The mixed colour is Error.")
        f.write("The mixed colour is Error.")  #writing to file
