What is characteristic of a program written in a High-Level Language (HLL)?
Contains preprocessor directives like #define and #include
Which stage does the pre-processor handle in a language processing system?
Removing #include directives and expanding #define directives
What is the main characteristic of Assembly Language?
Intermediate state between binary form and high-level language
What specifically does an assembler provide for a platform?
Conversion of assembly language into machine code specific to the platform
What distinguishes a transcompiler from other types of compilers?
Translates source code between different programming languages
What is the purpose of the eye() function in NumPy?
To create an identity matrix
What is the purpose of the k parameter in the eye() function?
It specifies the diagonal we require, with k > 0 meaning the diagonal above the main diagonal and k < 0 meaning the diagonal below the main diagonal
What is the purpose of the eval() function in Python?
To evaluate a string as a valid Python expression and execute it
What is the purpose of the swapcase() method in Python?
To convert all lowercase letters to uppercase and all uppercase letters to lowercase
What is the purpose of the join() method in Python?

What is a parent class?
The class being inherited from
What is a child class?
The class that inherits from another class
How do you create a child class that inherits from a parent class?
By sending the parent class as a parameter when creating the child class

What is printed by the following code?
fruits = ["apple", "banana", "cherry"] for x in fruits: if x == "banana": continue print(x)
apple cherry
Test your knowledge on source-to-source compilers, also known as transcompilers or transpilers, which translate code from one programming language to another. Explore language processing systems and the role of compilers in converting high-level languages to machine-understandable instructions.
