Which of the following is the correct way to define a variable in Python?
a) int x = 5
b) x := 5
c) x = 5
d) let x = 5
c) x = 5
Explain the difference between a list and a tuple in Python. Provide an example of each.
A list is mutable, meaning it can be modified after its creation, while a tuple is immutable, meaning it cannot be changed once created. Example of a list: my_list = [1, 2, 3]; Example of a tuple: my_tuple = (1, 2, 3)
Write a Python program that prints all even numbers from 1 to 20 using a for loop.
```python
for i in range(1, 21):
if i % 2 == 0:
print(i)
~~~
Complete the following function to calculate the factorial of a given number n:
```python
def factorial(n):
if n == 0:
return 1
else:
__________
~~~
```python
def factorial(n):
if n == 0:
return 1
else:
return n * factorial(n - 1)
~~~
Design a Python class named Car that has attributes for make, model, and year. Include a method to display the car’s information.
Example usage
```python
class Car:
def __init__(self, make, model, year):
self.make = make
self.model = model
self.year = year
def display_info(self):
print(f"{self.year} {self.make} {self.model}")
my_car = Car(“Toyota”, “Corolla”, 2020)
my_car.display_info()

When asking ChatGPT for help with a coding problem, what are two key pieces of information you should always include in your question?
The specific error message (if any) and a clear description of what you are trying to achieve.
Explain why it is important to avoid plagiarism in programming assignments and list two strategies to ensure your work is original.
Avoiding plagiarism is important because it ensures academic integrity and demonstrates your own understanding of the material. Two strategies to ensure originality are: 1) Writing code from scratch and 2) Properly citing any code snippets or libraries used from external sources.
Analyze how participating in online coding communities can enhance your coding skills. Provide two specific examples.
Participating in online coding communities can enhance coding skills by providing exposure to different coding styles and solutions to common problems. For example, contributing to open-source projects can improve collaborative skills, and engaging in coding challenges can help identify and fill knowledge gaps.
Which of the following is a common coding convention in Python?
c) Using snake_case for variable names
Which of the following is NOT a reserved word in Python?
c) true
Write a Python program that asks the user for a number and prints “Positive” if the number is greater than zero, “Negative” if it is less than zero, and “Zero” if it is exactly zero.
```python
number = int(input(“Enter a number: “))
if number > 0:
print(“Positive”)
elif number < 0:
print(“Negative”)
else:
print(“Zero”)
~~~
Explain how flowcharts can help in solving programming problems and provide an example scenario where a flowchart would be useful.
Flowcharts help by providing a visual representation of the sequence of steps in an algorithm, making it easier to understand and debug the logic. For example, a flowchart would be useful in planning the logic for a complex conditional statement in a program.
What is Google Colab and how can it be used for coding in Python?
Google Colab is a cloud-based coding environment that allows users to write and execute Python code in a web browser. It is particularly useful for data analysis, machine learning, and collaborating on coding projects.
Write a Python function that takes a number as input and returns a list of all its multiples up to 100.
Example usage
```python
def find_multiples(n):
multiples = []
for i in range(1, 101):
if i % n == 0:
multiples.append(i)
return multiples
print(find_multiples(5))
