1. Write a function to perform addition, multiplication and subtraction.
2. Write a code using def function to convert a DNA of 9 nucleotides into a Protein. And print the output.
Sample Answer
Sample Answer
# Function to perform addition, multiplication, and subtraction
def perform_operations(num1, num2, operation):
if operation == ‘add’:
return num1 + num2
elif operation == ‘multiply’:
return num1 * num2
elif operation == ‘subtract’:
return num1 – num2
else:
return “Invalid operation. Please choose from ‘add’, ‘multiply’, or ‘subtract’.”
# Test the function
result_add = perform_operations(5, 3, ‘add’)
result_multiply = perform_operations(5, 3, ‘multiply’)
result_subtract = perform_operations(5, 3, ‘subtract’)
print(“Addition result:”, result_add)
print(“Multiplication result:”, result_multiply)
print(“Subtraction result:”, result_subtract)
