What is CLI tools ?
A command line interface (CLI) is a text-based user interface (UI) used to run programs, manage computer files, and interact with a computer. A command line interface is also known as a command line user interface, console user interface, or character user interface.
Why do we use CLI tools ?
The CLI is a command line utility that accepts text input and executes operating system functions. In the 1960s, this was the only way to interact with a computer, as only computer terminals were in use. In the 1970s and 1980s, command line input was widely used on Unix systems and personal computer systems such as MS-DOS and Apple DOS.

Answer:
ababababab
Explanation:
The code above is written in python and python uses indentation .So let me rephrase the code accordingly and explain what the code really do.
Note x and y is a global variable which can be used by any of the function declared. According to the question x and y are 2 and 3 respectively
The first block of code describes a function f1 without any argument but the code should return the string "ab"
def f1():
return "ab"
The second block of code defines a function f2 and returns the value of f1 multiply by x. This means you are multiplying the string "ab" by 2 which will be equals to abab
def f2():
return f1() * x
The third block of code declared a function f3 and returns the sum of f2 and product of f1 and y. using PEMDAS principle the multiplication aspect will be solved first so, ab × 3 = ababab, then we add it to f2 . ababab + abab = ababababab.
def f3():
return f2() + f1() * y
Finally, we print the function f3 value to get ababababab
print(f3())
If you run the code on your IDE like below you will get ababababab
x = 2
y = 3
def f1():
return "ab"
def f2():
return f1() * x
def f3():
return f2() + f1() * y
print(f3())
