What are the two parts of a CPU?
There are 2 parts of the CPU: The ALU and Control Unit. The Arithmetic Logic Unit (ALU) performs arithmetic operations (such as addition and subtraction) and logical operations (such as comparing two values).

What type of loop structure repeats the code a specific number of times?
The for loop as a Count-Controlled loop iterates a specific number of times. In the for clause, variable is the name of a variable. Inside the brackets is a sequence of values, that is comma separated. (in Python this is called a list).
Is Python sensitive to block structuring of code?
The Python language is not sensitive to block structuring of code. The if statement causes one or more statements to execute only when a Boolean expression is true. Python allows you to compare strings, but it is not case sensitive.
