Complete Exam Questions And
Correct Answers
Indentation in Python
Python uses indentation (spaces or tabs at the start of a line) to define code
blocks instead of braces. Consistent indentation is required for structures like
if statements, loops, and function definitions.
Variable in Python
A variable is a named reference to a value in memory. You create one by
simply assigning a value to a name using =.
Basic data types in Python
Important built-in data types include Integer (int), Floating-point (float), String
(str), Boolean (bool), and nonetype.
Integer in Python
Whole numbers (e.g. 42, -5).
Floating-point in Python
Decimal numbers (e.g. 3.14, 0.5).
String in Python
Text sequences in quotes (e.g. 'Hello').
Boolean in Python
Truth values True or False.
Nonetype in Python
The special value None indicating 'no value.'
Type checking in Python
You can use the type() function to check an object's type. For example,
type(42) returns <class 'int'>.
Type conversion in Python

,Use Python's built-in conversion functions like int(), float(), str(), and bool().
Int() function
Converts a string to an integer. For example, int('123') converts '123' to 123.
Str() function
Converts a number to a string. For example, str(123) converts 123 to '123'.
Operators in Python
Operators are symbols that perform operations on values, including arithmetic
and comparison operators.
Arithmetic operators in Python
Include + (addition), - (subtraction), (multiplication), / (division), // (floor
division), % (modulus), and * (exponentiation).
Comparison operators in Python
Include == (equal to), != (not equal), <, <=, >, >=.
Common pitfall in Python
Using = instead of == in a condition, which causes a syntax error.
// operator in Python
The // operator is the floor division operator.
Reading from files in Python
Involves opening a file and counting lines.
Python's built-in documentation
Can be accessed using the help() function.
Dynamic typing in Python
Python is dynamically typed, meaning you don't declare types explicitly.
Reassigning variables in Python
A variable can refer to data of any type and can be reassigned to a different
type later.
Common advice for D522
Mastering core Python basics, doing all Zybooks labs and quizzes, and
practicing coding exercises.
Fundamental data types and structures in Python
Include strings, lists, tuples, sets, and dictionaries.

, Example of improper indentation
An improperly indented line will cause an indentationerror or unexpected
behavior.
Floor Division
It divides two numbers and returns the largest integer less than or equal to the
result.
Example of Floor Division
17 // 5 evaluates to 3 because 17/5 is 3.4 and floor division drops the
fractional part.
Negative Floor Division Example
-5 // 2 gives -3 (since -2.5 floored is -3).
Modulo Operator (%)
The % operator computes the remainder of a division.
Example of Modulo
7 % 3 equals 1 (since 7 divided by 3 has remainder 1).
Even Divisibility Check
X % 2 == 0 checks if x is even.
Cycling Through Values
Using i % 7 to wrap an index every 7 elements.
Leap Year Determination
Year % 4 checks if a year is a leap year.
Modulo with Negative Numbers
Python's result will have the same sign as the divisor.
Logical Operators in Python
Logical operators combine or modify boolean values.
Logical AND
And returns True if both operands are True.
Logical OR
Or returns True if at least one operand is True.
Logical NOT
Not negates a boolean value.
