FAQs

Use flask. request. args. get() to get parameters from a URL:

  • @app. route("/")
  • def hello():
  • return request. args. get("page_number")
  • app. run(host="0.0.0.0", port=8080)

The benefits of using Query Arguments in Flask are:

  • It allows you to specify a query string with a variable.
  • It can be used to filter the data that is loaded into the database.
  • You can use it to control the number of rows that are returned from a database query.

Arguments are an important part of any query, and it is important to know what they are. There are two types of arguments:

  • Content arguments- These are the words that will be used to find content on a given topic. For example, if someone wanted to find articles about the benefits of using AI writers, they could use "benefits of using AI writers" as their argument.
  • Query arguments- These are words that will be used to filter out search results based on specific criteria. For example, if someone wanted articles with a certain word count or written by a specific person, they would use those terms as their query argument.

A query argument is a parameter that is passed to the Flask application. It can be used to specify the number of rows to be returned, sort order, or filtering criteria.

You can use the following code to create a Flask application that returns 10 rows:

  • def index(request):
  • return render_template('index.html',
  • rows=10)
