Which characteristic is a fundamental difference between Python and languages like C++ or Java?
Which characteristic is a fundamental difference between Python and languages like C++ or Java?
- Python does not support Object-Oriented Programming (OOP) principles.
- Python uses indentation to define code blocks, whereas C++ and Java typically use curly braces. (correct)
- Python relies on explicit compilation before execution, unlike interpreted languages.
- Python is a statically typed language, requiring variable types to be declared explicitly.
Consider the following Python code snippet:
class Animal:
def __init__(self, name, species):
self.name = name
self.species = species
def display(self):
print(f'{self.name} is a {self.species}')
my_animal = Animal('Simba', 'Lion')
my_animal.display()
What is the purpose of the __init__ method in the Animal class?
Consider the following Python code snippet:
class Animal:
def __init__(self, name, species):
self.name = name
self.species = species
def display(self):
print(f'{self.name} is a {self.species}')
my_animal = Animal('Simba', 'Lion')
my_animal.display()
What is the purpose of the __init__ method in the Animal class?
- It is a method used to display the class name.
- It is used to inherit properties from another class.
- It is used to delete an instance of the class.
- It is a special method that Python calls when an object is created from the class; it initializes the attributes of the object. (correct)
Which of the following is NOT a basic data type in Python?
Which of the following is NOT a basic data type in Python?
- Integer
- String
- Float
- Tuple (correct)
What output will the following Python code produce?
x = 5
y = 2
print(x // y)
What output will the following Python code produce?
x = 5
y = 2
print(x // y)
Consider the following Python code:
age = 17
if age >= 18:
print('Eligible to vote')
else:
print('Not eligible to vote')
What will be the output of this code?
Consider the following Python code:
age = 17
if age >= 18:
print('Eligible to vote')
else:
print('Not eligible to vote')
What will be the output of this code?

Which loop type is most suitable for iterating through the items of a dictionary in Python?
Consider the following function definition in Python:
def greet(name='Guest'):
print(f'Hello, {name}!')
What is the purpose of the name='Guest' in the function definition?

Study Notes
- Study guide for MGIS 3315, covering weeks 1-7.
Python Introduction & OOP Concepts (Week 1)
- Python is an interpreted language executing code line by line.
- Python uses indentation for blocks instead of {}.
print("Hello, World!")displays output.- Object-Oriented Programming (OOP) uses classes as blueprints for creating objects.
- An object is an instance of a class.
- Example of a Car class definition:
class Car:def __init__(self, brand, model):self.brand = brandself.model = modeldef display(self):print(f"Car: {self.brand} {self.model}")
- Creating an object of the Car class:
my_car = Car("Toyota", "Corolla") - Calling the display method:
my_car.display()outputs "Car: Toyota Corolla"
Data Types, Variables, Expressions (Week 2)
- Basic data types include Integer, Float, String, Boolean, List, and Dictionary.
- Common expressions and operators: +, -, *, /, //, %, **.
- Example variable assignments:
x = 10,y = 3.14,name = 'Caren',is_valid = True
Conditional Statements (Week 3)
- If-Else statements are used for decision-making.
- Example:
age = 20if age >= 18:print('You are an adult.')else:print('You are a minor.')
- Comparison operators include ==, !=, <, >, <=, >=.
- Logical operators include and, or, not.
Conditional Statements (Continued) - Week 4
- Nested If Statements allow for multiple conditions.
- Ternary Operator (Short If-Else) example:
x = 10result = 'Even' if x % 2 == 0 else 'Odd'print(result)outputs "Even"
Data Structures (Week 5)
- Lists are ordered and mutable collections.
- Dictionaries are unordered key-value pairs.
- Tuples are immutable and ordered collections.
- Sets are unordered collections of unique values.
- Looping through Data Structures can be done using
forandwhileloops.
Data Structures (Continued) Week 6
- Iterating through lists and dictionaries is useful for accessing each of their values.
Whileloops are useful for repeating actions.
Data Structures & Functions (Week 7)
- Functions involve defining and calling reusable blocks of code.
- Example of default parameters in a function:
def greet(name='Guest') - Returning multiple values from a function:
def get_coordinates(): return (10, 20)
