D522 Python for IT Automation - Set 1 - Part 1

Correct Answer: print()

The built-in print() function displays output to the standard console in Python.

Correct Answer: Using the # symbol

In Python, a comment begins with # and continues to the end of the line.

Correct Answer: int

The whole number 42 is an integer, so Python assigns it the int type.

Correct Answer: str

The str (string) type represents sequences of characters, written in single or double quotes.

Correct Answer: True and False

Python's Boolean type has exactly two values, True and False, capitalized.

Correct Answer: count = 5

Python uses simple assignment with =, and variables are declared implicitly: count = 5.

Correct Answer: int()

The int() function converts a numeric string or float into an integer, for example int('42').

Correct Answer: len()

The built-in len() function returns the number of items in a sequence such as a list or string.

Correct Answer: items[0]

Python uses zero-based indexing, so items[0] accesses the first element.

Correct Answer: %

The % operator returns the remainder of division, such as 7 % 3 giving 1.

Correct Answer: Exponentiation (raises to a power)

The ** operator raises a number to a power, so 2 ** 3 equals 8.

Correct Answer: Integer (floor) division

The // operator performs floor division, discarding the fractional part, so 7 // 2 equals 3.

Correct Answer: def

Python functions are defined with the def keyword, followed by the name and parameters.

Correct Answer: return

The return statement passes a value back to the caller and ends the function's execution.

Correct Answer: Indentation

Python uses indentation to define code blocks, unlike languages that use braces.

Correct Answer: for item in data:

Python's for loop syntax iterates directly over a sequence: for item in data:

Correct Answer: range()

The range() function produces a sequence of integers commonly used to control for loops, for example range(5).

Correct Answer: 0, 1, 2

range(3) generates the numbers 0, 1, 2, starting at 0 and stopping before 3.

Correct Answer: Repeating code as long as a condition is true

A while loop repeatedly executes its body as long as the given condition remains true.

Correct Answer: break

The break statement terminates the enclosing loop immediately, transferring control to the code after it.
