Practice

1. What is the correct command to install Django using pip?

easy

A. pip install django

B. install django pip

C. django install pip

D. pip django install

Solution

1. Step 1: Understand pip installation syntax

   The standard way to install Python packages is using pip install package_name.

2. Step 2: Apply to Django package

   Replacing package_name with django gives pip install django.

3. Final Answer:

   pip install django -> Option A

4. Quick Check:

   pip install django = D [OK]

Hint: Use 'pip install django' to install Django quickly [OK]

Common Mistakes:

• Mixing order of words in the command
• Using 'install' before 'pip'
• Forgetting 'install' keyword

2. Which of the following commands correctly checks the installed Django version?

easy

A. python django version

B. django --version

C. pip django version

D. django-admin --version

Solution

1. Step 1: Identify the command to check Django version

   The command django-admin --version is the standard way to check Django's installed version.

2. Step 2: Verify other options

   Other options are incorrect because they are not valid commands or miss the --version flag.

3. Final Answer:

   django-admin --version -> Option D

4. Quick Check:

   django-admin --version = A [OK]

Hint: Use 'django-admin --version' to check Django version [OK]

Common Mistakes:

• Using 'django --version' which is invalid
• Trying 'pip django version' which is not a command
• Forgetting the '--version' flag

3. After running pip install django, what will be the output of python -m django --version if Django 4.2 is installed?

medium

A. 4.2

B. django 4.2

C. Version 4.2

   The command python -m django --version outputs only the version number, e.g., '4.2'.

2. Step 2: Match output to options

   Only 4.2 matches the expected plain version number output.

3. Final Answer:

   4.2 -> Option A

4. Quick Check:

   python -m django --version = 4.2 [OK]

Hint: Version command outputs just the number like '4.2' [OK]

Common Mistakes:

• Expecting extra text like 'Version' or 'django' in output
