SECTION ONE: QUESTIONS 1–100
,1. What is the output of print(type(1/2)) in Python 3?
A. <class 'int'>
🟢 B. <class 'float'>
C. <class 'number'>
D. <class 'decimal'>
🔴 RATIONALE: In Python 3, the division operator / always returns a float, even if
the result is a whole number.
2. Which PEP 8 guideline is recommended for variable naming?
A. CamelCase
🟢 B. snake_case
C. SCREAMING_SNAKE_CASE
D. PascalCase
🔴 RATIONALE: PEP 8 recommends snake_case for functions and variables.
3. How do you handle a generic exception in Python?
A. except Error:
B. except Exception:
🟢 C. except:
D. except catch:
🔴 RATIONALE: An empty except clause catches all exceptions, although it is
generally discouraged for specific error handling.
,4. Which data structure is immutable?
A. list
B. dict
🟢 C. tuple
D. set
🔴 RATIONALE: Tuples are defined as immutable sequences in Python.
5. What is the primary purpose of the 'with' statement?
A. To create a loop
B. To manage decorators
🟢 C. To manage context resources (e.g., file closing)
D. To import modules
🔴 RATIONALE: The with statement simplifies exception handling by encapsulating
standard uses of try/finally in context managers.
6. Which keyword is used to handle multiple exceptions?
A. try-except-finally
🟢 B. except (Exception1, Exception2)
C. catch (Exception1, Exception2)
D. handle (Exception1, Exception2)
🔴 RATIONALE: Python allows catching multiple exceptions by passing them as a
tuple to the except clause.
, 7. How do you declare a private variable in a class?
A. Using a single underscore prefix
🟢 B. Using a double underscore prefix
C. Using the private keyword
D. Using the # prefix
🔴 RATIONALE: A double underscore prefix triggers name mangling, which is the
standard way to indicate private class members.
8. What is the difference between == and is?
A. No difference
B. == checks type, is checks value
🟢 C. == checks equality, is checks identity
D. == checks identity, is checks equality
🔴 RATIONALE: == compares values (equality), while is compares object identity
(memory address).
9. Which module is standard for handling CSV files?
A. data
B. json
🟢 C. csv
D. file
🔴 RATIONALE: The csv module implements classes to read and write tabular
data in CSV format.
