Study Notes

Data Types in Python

  • Strings: sequences of characters, e.g. "Hello World!"
  • Boolean: represents truth values, either True or False
  • Scalar objects: cannot be subdivided, e.g. int, float, bool, NoneType
  • Non-scalar objects: have internal structure that can be accessed

String Operations

  • Concatenation: using the + operator, e.g. "College of" + "Technological" + "Innovation"
  • Repetition: using the * operator, e.g. "Hello World!" * 2
  • Slicing: using the [] and [:] operators, e.g. "Hello World!"[0] returns the first character, "Hello World!"[2:5] returns characters from the 3rd to the 5th

Boolean Operations

  • Boolean values: True or False
  • Assigning Boolean values to variables: e.g. zero = False, one = True
  • Evaluating Boolean expressions: e.g. 45 &gt; 35 returns True, 89 &lt; 79 returns False

Operators

  • Arithmetic operators: +, -, *, /, %, **, etc.
  • Relational operators: ==, !=, &gt;, &lt;, &gt;= , &lt;=
  • Logical operators: and, or, not
  • Operator precedence: parentheses, **, *, /, +, -, etc.

Variables and Data Types

  • Binding variables and values: using the = operator, e.g. result = 89
  • Retrieving values: using the variable name, e.g. print(result)
  • Type conversions: using the type() function, e.g. float(3) converts the integer 3 to a float 3.0

Abstracting Expressions

  • Assigning names to values of expressions: using the = operator, e.g. result = 3 + 4 * 5
  • Evaluating expressions: using the print() function, e.g. print(result)

Course Introduction

  • Introduction to Programming and Problem Solving (SWE225)
  • Topics: Variables and Data Types, Basic Data Types in Python, Operators, etc.
