In Flask, request.form.get() and request.args.get() are methods to get data from a form submitted using the POST and GET methods, respectively.
The main difference between these two methods is the way the form data is submitted and accessed.
When a form is submitted using the POST method, the form data is sent as part of the request body. In Flask, you can access this data using the request.form object, which is a dictionary-like object that contains the form data. To get a specific value from the form data, you can use the request.form.get() method, which takes the name of the form field as an argument and returns its value.
For example, if you have a form field with the name 'username', you can get its value like this:
username = request.form.get('username')
On the other hand, when a form is submitted using the GET method, the form data is sent as query parameters in the URL. In Flask, you can access this data using the request.args object, which is also a dictionary-like object that contains the query parameters in the URL. To get a specific value from the query parameters, you can use the request.args.get() method, which takes the name of the parameter as an argument and returns its value.
For example, if you have a query parameter with the name 'page', you can get its value like this:
page = request.args.get('page')
In summary, the main difference between request.form.get() and request.args.get() is the way the form data is submitted and accessed. request.form.get() is used to get data from a form submitted using the POST method, while request.args.get() is used to get data from a form submitted using the GET method.
