Practice - 5 Tasks

1fill in blank

easy

Complete the code to make a GET request to the API endpoint.

Rest API

response = requests.[1]('https://api.example.com/data')

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 'post' instead of 'get' when only retrieving data.

Using 'put' or 'delete' which are for updating or deleting data.

The get method sends a GET request to the specified URL to retrieve data.

Complete the code to print the status code of the API response.

Rest API

print(response.[1])

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 'text' or 'content' which contain the response body, not the status code.

Using 'json' which parses the response body, not the status code.

The status_code attribute shows the HTTP status code returned by the API.

Fix the error in the code to parse the JSON response correctly.

Rest API

data = response.[1]()

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 'text' or 'content' which return raw strings or bytes.

Using 'status_code' which is an integer, not the response body.

The json() method parses the response body as JSON and returns a Python dictionary.

4fill in blank

hard

Fill both blanks to check if the response status code is 200 and print success.

Rest API

if response.[1] == [2]:
    print('Success!')

Drag options to blanks, or click blank then click option'

Astatus_code

Btext

C200

Djson

💡 Hint

Common Mistakes

Comparing the response text to '200' instead of the status code.

Using 'json' or 'text' instead of 'status_code' for the check.

Check if response.status_code equals 200 which means the request was successful.

5fill in blank

hard

Fill both blanks to extract the 'name' field from the JSON response and print it.

Rest API

data = response.[1]()
name = data[[2]]
print(name)

Drag options to blanks, or click blank then click option'

Ajson

B'name'

C'id'

Dtext

💡 Hint

Common Mistakes

Using 'text' instead of 'json' to parse the response.

Accessing the wrong key like 'id' instead of 'name'.

Use json() to parse the response, then access the 'name' key to get the value.

Practice

1. What does a GET request in an API usually do?

easy

A. It asks the server to send data back.

B. It sends data to the server to be saved.

C. It deletes data from the server.

D. It updates existing data on the server.

Solution

1. Step 1: Understand the GET method

   The GET method is used to request data from a server without changing it.

2. Step 2: Identify the purpose of GET in API

   GET asks the server to send data back to the client.

3. Final Answer:

   It asks the server to send data back. -> Option A

4. Quick Check:

   GET = Request data [OK]

Hint: GET means get data from server, no changes made [OK]

Common Mistakes:

• Confusing GET with POST or DELETE methods
• Thinking GET changes data on server
• Mixing up request and response roles

2. Which of these is the correct way to write a simple GET request URL?

easy

A. POST /api/data HTTP/1.1

B. DELETE /api/data HTTP/1.1

C. GET /api/data HTTP/1.1

D. PUT /api/data HTTP/1.1

Solution

1. Step 1: Identify HTTP methods

   GET is the method used to request data, so the request line must start with GET.

2. Step 2: Check the request format

   The correct format is "GET /path HTTP/1.1" for a GET request.

3. Final Answer:

   GET /api/data HTTP/1.1 -> Option C

4. Quick Check:

   GET request line starts with GET [OK]

Hint: GET requests start with GET keyword in HTTP line [OK]

Common Mistakes:

• Using POST, DELETE, or PUT instead of GET
• Wrong HTTP version or missing method
• Confusing request line with response line

3. Given this API response snippet:

{"status":200,"data":{"name":"Alice","age":30}}

What does the status code 200 mean?

medium

A. The request was unauthorized.

B. The requested resource was not found.

C. There was a server error processing the request.

D. The request was successful and data is returned.

Solution

1. Step 1: Understand HTTP status codes

   Status code 200 means the request succeeded and the server returned the requested data.

2. Step 2: Match status code to meaning

   200 is standard for success; 404 means not found, 500 means server error, 401 means unauthorized.

3. Final Answer:

   The request was successful and data is returned. -> Option D

4. Quick Check:

   Status 200 = Success [OK]

Hint: 200 means OK, request worked fine [OK]

Common Mistakes:

• Confusing 200 with error codes like 404 or 500
• Thinking 200 means no data returned
• Mixing status codes with data content

4. You send a GET request to an API but get no response. Which of these is a likely cause?

medium

A. The server returned status code 200.

B. The API endpoint URL is incorrect or misspelled.

C. You used the GET method instead of POST.

D. Your request included a valid Authorization header.

Solution

1. Step 1: Check the URL correctness

   If the URL is wrong or misspelled, the server won't respond properly or may not be found.

2. Step 2: Evaluate other options

   Using GET instead of POST may cause wrong data but usually gets a response; status 200 means success; valid Authorization helps access.

3. Final Answer:

   The API endpoint URL is incorrect or misspelled. -> Option B

4. Quick Check:

   Wrong URL = No response [OK]

Hint: Check URL spelling first if no response [OK]

Common Mistakes:

• Assuming method error causes no response
• Ignoring URL typos
• Confusing status codes with no response

5. You want to get user info from an API at https://api.example.com/users/123. Which is the best way to check if your request worked?

hard

A. Check if the response status code is 200 and the data contains user details.

B. Check if the request method was POST and the server returned 404.

C. Check if the response status code is 500 and the data is empty.

D. Check if the URL contains the word 'users' and the method is DELETE.

Solution

1. Step 1: Understand success criteria for API requests

   A successful GET request returns status 200 and the expected data.

2. Step 2: Evaluate options for correctness

   POST method and 404 means not found; 500 means server error; DELETE method is for removing data, not getting it.

3. Final Answer:

   Check if the response status code is 200 and the data contains user details. -> Option A

4. Quick Check:

   Status 200 + data = success [OK]

Hint: Success = status 200 + expected data [OK]

Common Mistakes:

• Confusing POST with GET for data retrieval
• Ignoring status codes meaning
• Checking wrong HTTP methods for GET requests
