Use the 'FURL' Class Library in Python to add and modify the URL parameter

Using the `Furl` library in Python can easily achieve the addition and modification of the number of parameters in the URL.`Furl` is an extension based on the Python standard library` Urlparse`. It provides a more concise, easy -to -use and friendly API, allowing us to easily handle the various operations of URL. The process of adding and modifying the URL parameter in Python to add and modify the URL parameter is as follows: 1. Install the `FURL` Library.You can use the `pip` command to install: pip install furl 2. Import the `FURL` Library. python from furl import furl 3. Create an `Furl` object and pass the original URL to the constructor. python url = furl("https://www.example.com/path?param1=value1") Here we created a `Furl` object` url` and passed a string containing the original URL. 4. Add and modify parameters. python url.args['param2'] = 'value2' url.args['param1'] = 'updated_value1' Use the `url.args` dictionary to add and modify the parameters.In the above code, we added a new parameter `param2` and modified the values of existing parameters` Param1`. 5. Output the URL after the update. python print(url.url) Use the `url.url` property to obtain the updated URL string. It should be noted that the `Furl` library can not only add and modify the URL parameter, but also perform other URL operations, such as deleting parameters, extracting parameters, analysis of relative URL, and so on.It provides rich APIs to meet our various needs for URLs. The complete Python code is shown below: python from furl import furl url = furl("https://www.example.com/path?param1=value1") url.args['param2'] = 'value2' url.args['param1'] = 'updated_value1' print(url.url) The above code will output the updated URL string. Note that before the code is executed, it is necessary to ensure that the `Furl` library has been installed, and it has been imported.If it is not installed, you need to use the `pip` command for installation.
