Path parameters in FastAPI - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to define a path parameter named 'item_id' in the route.

FastAPI

from fastapi import FastAPI
app = FastAPI()

@app.get("/items/[1]")
async def read_item(item_id: int):
    return {"item_id": item_id}

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

A"{item_id}"

B"item_id"

C"<item_id>"

D"[item_id]"

💡 Hint

Common Mistakes

Using quotes without braces like 'item_id' instead of '{item_id}'.

Using angle brackets or square brackets instead of curly braces.

In FastAPI, path parameters are defined using curly braces in the route path, like '/items/{item_id}'.

2fill in blank

medium

Complete the code to declare the type of the path parameter 'user_id' as string.

FastAPI

from fastapi import FastAPI
app = FastAPI()

@app.get("/users/{user_id}")
async def read_user(user_id: [1]):
    return {"user_id": user_id}

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

💡 Hint

Common Mistakes

Using 'int' when the parameter should be a string.

Omitting the type annotation.

To specify a string path parameter in FastAPI, use 'str' as the type annotation.

3fill in blank

hard

Fix the error in the path parameter declaration to correctly capture 'order_id' as an integer.

FastAPI

from fastapi import FastAPI
app = FastAPI()

@app.get("/orders/[1]")
async def read_order(order_id: int):
    return {"order_id": order_id}

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

A"order_id"

B"[order_id]"

C"<order_id>"

D"{order_id}"

💡 Hint

Common Mistakes

Using quotes without braces around the parameter name.

Using angle or square brackets instead of curly braces.

Path parameters must be enclosed in curly braces in the route path to be recognized by FastAPI.

4fill in blank

hard

Fill both blanks to create a path parameter 'category' of type string and return it in the response.

FastAPI

from fastapi import FastAPI
app = FastAPI()

@app.get("/categories/[1]")
async def read_category(category: [2]):
    return {"category": category}

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

A{category}

Bint

Cstr

Dfloat

💡 Hint

Common Mistakes

Not using curly braces in the route path.

Using the wrong type annotation like 'int' or 'float'.

The path parameter must be in curly braces in the route, and the type annotation should be 'str' for a string.

5fill in blank

hard

Fill all three blanks to define a path parameter 'product_id' as an integer and return it in a dictionary with key 'product'.

FastAPI

from fastapi import FastAPI
app = FastAPI()

@app.get("/products/[1]")
async def read_product([2]: [3]):
    return {"product": [2]

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

A{product_id}

Bproduct_id

Cint

Dstr

💡 Hint

Common Mistakes

Mismatch between path parameter name and function parameter name.

Wrong type annotation like 'str' instead of 'int'.

The path parameter must be in curly braces in the route, the function parameter name must match, and the type should be 'int' for an integer.
