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.
Short-Circuit Evaluation -✓✓In (expr1 and expr2), expr2 is only evaluated if expr1
is True.
String Concatenation -✓✓Joining strings end-to-end using the + operator.
Example of String Concatenation -✓✓"Hello, " + "world!" results in "Hello,
world!".
