Why APIs matter in Flask - Quick Recap

Recall & Review

beginner

What is an API in simple terms?

An API is like a waiter in a restaurant. It takes your order (request), tells the kitchen (server) what you want, and brings back your food (response). It helps different software talk to each other easily.

Why do developers use APIs?

Developers use APIs to save time and effort. Instead of building everything from scratch, they can use APIs to get data or services from other programs quickly and safely.

How do APIs help in building web apps with Flask?

Flask APIs let your web app talk to other apps or devices. For example, your app can get weather info from another service or let mobile apps get data from your server.

What is the main benefit of using APIs for users?

Users get better experiences because APIs let apps share data and features. For example, logging in with Google uses an API to make signing in easy and safe.

How do APIs support teamwork in software projects?

APIs let different teams work on parts of a project separately. One team can build the API while others use it to build apps, making work faster and organized.

What does an API do in software?

A Allows different software to communicate

B Stores data permanently

C Designs user interfaces

D Runs the computer hardware

APIs let different software programs talk to each other by sending and receiving data.

Why are APIs important in Flask web apps?

A They make the app run faster on the computer

B They help the app share data with other apps

C They change the app's colors automatically

D They store user passwords in plain text

Flask APIs let your app send and receive data from other apps or devices.

Which is a real-life example of using an API?

A Charging your phone battery

B Typing a document in a word processor

C Watching a video on TV

D Logging in with Google on a website

Logging in with Google uses an API to connect your app with Google's login service.

How do APIs help software teams?

A By removing the need for testing

B By making all teams write the same code

C By letting teams build parts separately and connect them

D By slowing down the project

APIs let teams work independently on different parts and then connect them easily.

What is NOT a purpose of an API?

A Changing hardware settings directly

B Helping reuse code and services

C Improving user experience by sharing data

D Making software talk to each other

APIs do not change hardware settings; they help software communicate and share data.

Explain why APIs matter when building web applications with Flask.

Think about how apps talk to each other and how teams build parts.

Describe a simple real-life example that shows how an API works.

Imagine ordering food at a restaurant.
