2. What is CPython?

   • It’s the default, reference implementation of the C language, written in Python
   • It’s a programming language that is a supperset of the Python, designed to produce C-like performance with code written in Python
   • It’s the default, reference implementation of Python, written in the C language
   • It’s a programming that is a superset of the C language, designed to produce Python-like performance with code written in C

9. What is machine code?

   • A high-level programming language consisting of instruction lists that humans can read and understand 
   • A medium-level programming language consisting of the assembly code designed for the computer processor
   • A low-level programming language consisting of binary digits/bits that the computer reads and understands
   • A low-level programming language consisting of hexadecimal digits that make up high-level language instructions 

10. Select the true statements?(Select two answer)

    • Python is a good choice for creating and executing tests for applications
