💡 Hint

Common Mistakes

Using the wrong variable names or values.

Confusing keys and values in the dictionary.

This creates a dictionary where each quality is a key, and the value is the string 'important'.

Practice

1. What is the main goal of software engineering?

easy

A. To create software that works well and lasts long

B. To write code as fast as possible

C. To design hardware components

D. To manage computer networks

Solution

1. Step 1: Understand the purpose of software engineering

   Software engineering focuses on making software reliable and maintainable over time.

2. Step 2: Compare options with this purpose

   Only To create software that works well and lasts long matches this goal; others relate to speed, hardware, or networks, which are not main goals.

3. Final Answer:

   To create software that works well and lasts long -> Option A

4. Quick Check:

   Software engineering = reliable, lasting software [OK]

Hint: Focus on software quality and longevity [OK]

Common Mistakes:

• Confusing software engineering with hardware design
• Thinking speed of coding is the main goal
• Mixing software engineering with network management

2. Which of the following is a correct part of the software engineering process?

easy

A. Building physical computer parts

B. Installing operating systems only

C. Planning, coding, testing, and maintaining software

D. Designing websites without coding

Solution

1. Step 1: Identify key activities in software engineering

   Software engineering includes planning, coding, testing, and maintenance.

2. Step 2: Match options with these activities

   Only Planning, coding, testing, and maintaining software lists these activities; others describe unrelated tasks.

3. Final Answer:

   Planning, coding, testing, and maintaining software -> Option C

4. Quick Check:

   Software engineering = plan + code + test + maintain [OK]

Hint: Look for full software lifecycle steps [OK]

Common Mistakes:

• Confusing software engineering with hardware building
• Thinking installing OS is software engineering
• Assuming design without coding is software engineering

3. Consider this code snippet representing a software engineering task list:

tasks = ['plan', 'code', 'test', 'maintain']
completed = []
for task in tasks:
    completed.append(task.upper())
print(completed)

What will be the output?

medium

A. ['PLAN', 'CODE', 'TEST', 'MAINTAIN']

B. Error: .upper() not defined

C. ['Plan', 'Code', 'Test', 'Maintain']

D. ['plan', 'code', 'test', 'maintain']

Solution

1. Step 1: Understand the loop and method used

   The loop goes through each task and appends its uppercase version to completed.

2. Step 2: Apply .upper() to each string

   'plan' becomes 'PLAN', 'code' becomes 'CODE', and so on, resulting in all uppercase strings.

3. Final Answer:

   ['PLAN', 'CODE', 'TEST', 'MAINTAIN'] -> Option A

4. Quick Check:

   String.upper() converts to uppercase [OK]

Hint: Remember .upper() makes strings uppercase [OK]

Common Mistakes:

• Thinking .upper() capitalizes only first letter
• Expecting original list unchanged
• Assuming .upper() causes error

4. This code tries to add a new task to the software engineering process:

tasks = ['plan', 'code', 'test']
tasks.add('deploy')
print(tasks)

What is the problem?

medium

A. The 'deploy' task is misspelled

B. List object has no method 'add', should use 'append'

C. The print statement is missing parentheses

D. The list is empty, so add won't work

Solution

1. Step 1: Identify the data type and method used

   tasks is a list, but lists do not have an 'add' method.

2. Step 2: Correct method for adding to list

   To add an item to a list, use 'append' method, not 'add'.

3. Final Answer:

   List object has no method 'add', should use 'append' -> Option B

4. Quick Check:

   List.append() adds items, not add() [OK]

Hint: Use append() to add items to a list [OK]

Common Mistakes:

• Using add() instead of append() on lists
• Ignoring error messages about methods
• Thinking print needs no parentheses in Python 3

5. A team wants to improve their software by adding a new feature but also keep the software reliable and easy to maintain. Which software engineering practice helps achieve this best?

hard

A. Ignoring user feedback to save time

B. Adding features quickly without testing

C. Changing code randomly to find bugs

D. Writing clear code and testing thoroughly before release

Solution

1. Step 1: Identify practices that improve reliability and maintainability

   Clear code and thorough testing help keep software reliable and easy to maintain.

2. Step 2: Evaluate options for best practice

   Writing clear code and testing thoroughly before release supports quality and maintenance; others risk bugs or poor quality.

3. Final Answer:

   Writing clear code and testing thoroughly before release -> Option D

4. Quick Check:

   Clear code + testing = reliable software [OK]

Hint: Good code + testing = reliable, maintainable software [OK]

Common Mistakes:

• Rushing features without testing
• Ignoring user feedback
• Random code changes without plan
