Q1. An IT administrator is writing a script that will run nightly to inventory servers. The first line of the script must declare
the Python interpreter so the operating system can execute it without explicitly calling python. Which shebang line
correctly identifies the Python 3 interpreter on a typical Linux system?
A. #!/usr/bin/env python3
B. #!python3
C. #!/bin/python
D. # -*- coding: utf-8 -*-
Correct Answer: A
Rationale: The portable shebang #!/usr/bin/env python3 locates the Python 3 interpreter via the PATH environment variable and is the
recommended form for cross-system scripts. Options B and C either omit the full path or point to a non-standard location, while the
coding declaration is unrelated to interpreter selection.
Q2. A junior engineer pastes a multi-line configuration block into a Python script and notices that the code under an if
statement never executes even though the condition evaluates to True. The engineer used spaces for some lines and a
single tab for others. What is the most likely root cause of the silent failure?
A. Python treats inconsistent indentation as a logical block error and skips the indented suite at runtime
B. Mixing tabs and spaces raises IndentationError only when the block is empty
C. The interpreter silently coerces tabs to four spaces, changing the intended nesting
D. Inconsistent use of tabs and spaces produces an IndentationError that prevents the script from starting
Correct Answer: D
Rationale: Python 3 strictly forbids mixing tabs and spaces for indentation and raises IndentationError at parse time, stopping
execution before any code runs. The other choices misrepresent how the interpreter handles whitespace or invent silent runtime
behavior that does not exist.
Q3. While reviewing a colleague’s automation script, you encounter the statement x = 5; y = 5; print(x is y). On a
standard CPython interpreter the output is True. What does the is operator actually compare, and why can the result be
True for small integers?
A. It compares object identity (memory addresses); CPython interns small integers so both names refer to the same object
B. It compares values only; the is operator is an alias for == when both operands are integers
C. It compares types; because both variables are int the result is always True
D. It performs a bitwise comparison of the underlying C long values
Correct Answer: A
Rationale: The is operator tests object identity. CPython maintains a cache of small integer objects (−5 to 256), so two variables bound
to the same small integer value share a single object and therefore return True for is. Equality of value is tested with ==, not is.
Q4. A network engineer needs a constant that represents the maximum number of concurrent SSH sessions allowed by
policy. The value must never be reassigned accidentally later in the script. Which Python convention and language
feature best communicates and partially enforces this intent?
A. Wrap the integer inside a tuple of length one and never unpack it
B. Use the const keyword before the assignment so the interpreter raises an error on reassignment
C. Declare the name in ALL_CAPS and treat it as a constant by convention; Python has no true immutable binding for
integers
D. Store the value in a module-level __constant__ dictionary that the interpreter protects
Correct Answer: C
Rationale: Python has no const keyword or true constant objects for built-in types. The community convention of writing names in
ALL_CAPS signals that the value should not be reassigned. The other options invent language features that do not exist.

, Q5. You are debugging a script that builds a configuration string for a firewall rule. The engineer wrote: rule = "permit tcp
any any eq " + port where port is an integer variable. The script raises TypeError. What is the cleanest Python 3 fix that
also keeps the code readable?
A. rule = f"permit tcp any any eq {port}"
B. rule = "permit tcp any any eq " + str(port) using only the + operator and an explicit cast
C. rule = "permit tcp any any eq %s" % port (old-style formatting)
D. rule = "permit tcp any any eq {}".format(port) is the only acceptable modern approach
Correct Answer: A
Rationale: f-strings (formatted string literals) are the preferred, most readable way to interpolate values in Python 3.6+. They evaluate
the expression inside the braces and convert it automatically. While the other options can work, the f-string is the cleanest modern
solution.
Q6. A script must accept a hostname from the command line when the automation job is launched. The engineer wants
to keep the code compatible with both interactive testing and scheduled runs. Which module and function provide the
most idiomatic way to obtain the arguments that follow the script name?
A. import os; hostname = os.environ["HOSTNAME"]
B. import sys; hostname = sys.argv[1]
C. import argparse; hostname = argparse.get_argument(1)
D. import getopt; hostname = getopt.getopt()[0]
Correct Answer: B
Rationale: sys.argv is a list whose first element is the script name and subsequent elements are the positional arguments supplied on
the command line. For simple cases this is the most direct and commonly used approach. argparse is more powerful for complex CLIs
but is heavier for a single required argument.
Q7. An automation developer writes a helper function that should return both the number of lines processed and a list of
error messages. The function currently ends with return count, errors. What data structure does the caller actually
receive, and how should the caller unpack it?
A. A dictionary with keys "count" and "errors"
B. A list; the caller must index the result as result[0] and result[1]
C. A tuple; the caller can write count, errors = process_file(path)
D. Two separate return values that must be captured with two consecutive assignment statements
Correct Answer: C
Rationale: Python functions that appear to return multiple values actually return a single tuple. Tuple unpacking on the left-hand side of
an assignment is the idiomatic way to receive those values. The other descriptions mischaracterize the actual return type.
Q8. While examining a legacy script you find the statement print "Processing host", host. The script was written years
ago and now fails under Python 3. What is the precise reason for the failure and the minimal change required to restore
functionality?
A. The comma operator is no longer supported; rewrite as a single concatenated string
B. print became a function; change to print("Processing host", host)
C. String literals require the u prefix in Python 3
D. print statements must be indented under a main guard
Correct Answer: B
Rationale: In Python 2 print was a statement; in Python 3 it is a built-in function that requires parentheses. Adding the parentheses is
the minimal, correct migration step. The other explanations invent language changes that did not occur.
