DOCUMENT OVERVIEW:

• This comprehensive study guide contains 200 practice questions designed to
prepare you for the WGU E010 OA exam, covering all major programming concepts
in Python from basic syntax to object-oriented principles.

• Use this material by studying one section at a time, working through questions
systematically, and reviewing rationales carefully to understand not just the correct
answer but the underlying concepts.



SECTION 1: PYTHON BASICS & DATA TYPES (QUESTIONS 1-25)

1. What is the correct way to assign a value to a variable in Python?

A) variable = 10

B) 10 = variable

C) variable := 10

D) 10 -> variable

E) set variable to 10

A) variable = 10

RATIONALE: Python uses the single equals sign (=) for variable assignment. The left
side must be the variable name and the right side must be the value. Option B is
incorrect because you cannot assign to a literal value. Option C uses the walrus
operator (:=) which is for assignment expressions in specific contexts. Option D is
not valid Python syntax. Option E is not valid syntax.

,2. Which of the following is NOT a valid variable name in Python?

A) my_variable

B) _private

C) 2fast

D) myVariable

E) MyClass

C) 2fast

RATIONALE: Variable names in Python cannot begin with a number. They must start
with a letter or underscore. All other options follow valid naming conventions.
Option A uses underscores (valid). Option B starts with an underscore (valid).
Option D uses camelCase (valid). Option E uses PascalCase (valid).



3. What data type would the expression return in Python 3?

A) int

B) float

C) string

D) complex

E) Decimal

B) float

RATIONALE: In Python 3, the division operator (/) always returns a float, even if both
operands are integers. The result of would be 3.3333... (a float). To get integer
division (floor division), you would use the // operator, which would return 3.



4. Which of the following correctly represents a string in Python?

A) string = <Hello World>

,B) string = "Hello World"

C) string = [Hello World]

D) string = {Hello World}

E) string = 'Hello World'

B) string = "Hello World" and E) string = 'Hello World'

RATIONALE: Both double quotes and single quotes can be used to define strings in
Python. The question asks which is correct, and both B and E are valid. However, if
only one answer is expected, both are correct representations. Angle brackets (A),
square brackets (C), and curly braces (D) do not define strings; brackets define lists,
curly braces define sets or dictionaries.



5. What is the output of print(type(3.14))?

A) <class 'integer'>

B) <class 'float'>

C) <class 'number'>

D) <class 'decimal'>

E) float

B) <class 'float'>

RATIONALE: The type() function returns the data type of an object. For the value
3.14, type() returns <class 'float'> because it's a floating-point number. Option A
would be for integers. Option C is not a valid class name. Option D is incorrect;
Decimal is a separate type. Option E is incomplete.



6. Which statement is true about Python lists?

A) Lists are immutable

B) Lists are ordered and can contain different data types

, C) Lists cannot be modified after creation

D) Lists use curly braces

E) Lists do not support indexing

B) Lists are ordered and can contain different data types

RATIONALE: Lists in Python are mutable (can be changed), ordered (maintain
insertion order), and heterogeneous (can contain mixed data types). Option A is
incorrect; lists are mutable. Option C is wrong; lists can be modified. Option D is
wrong; lists use square brackets []. Option E is wrong; lists support indexing.



7. What will be the output of len("Python")?

A) 5

B) 6

C) 7

D) 8

E) Error

B) 6

RATIONALE: The len() function returns the number of characters in a string.
"Python" has 6 characters: P-y-t-h-o-n. Each character, including lowercase letters, is
counted.



8. How do you create a tuple with a single element?

A) tuple = (1)

B) tuple = (1,)

C) tuple = [1]

D) tuple = {1}
