Params in Python Requests

If you are working with APIs in Python, you might need to send additional parameters with your requests. These parameters can be sent in different ways. In this post, we will explore how to send parameters using the params argument in Python Requests library.

What are Parameters?

Parameters are additional pieces of information that can be sent with your request to an API. These parameters can be used by the API to filter, sort or search for specific data. For example, if you are using an API that returns a list of products, you can send a parameter to filter the products by their price or name.

Sending Parameters using Params Argument

The params argument in Python Requests library is used to send parameters with your request. This argument takes a dictionary of key-value pairs where the keys represent the parameter name and the values represent the parameter value. Here is an example:


import requests

url = 'https://api.example.com/products'
params = {'price': '100', 'category': 'electronics'}

response = requests.get(url, params=params)

print(response.json())

In this example, we are sending two parameters (price and category) with our request to the URL https://api.example.com/products. The values of these parameters are 100 and electronics, respectively.

Multiple Ways to Send Parameters

There are multiple ways to send parameters with your request. One way is to include the parameters in the URL itself. This is called a query string. Here is an example:


import requests

url = 'https://api.example.com/products?price=100&category=electronics'

response = requests.get(url)

print(response.json())

In this example, we have included the parameters (price and category) in the URL itself as a query string.

Another way to send parameters is to use the data argument instead of the params argument. The data argument is used when sending data to an API in the form of a POST request. Here is an example:


import requests

url = 'https://api.example.com/products'
data = {'name': 'Samsung Galaxy S20', 'price': '1000'}

response = requests.post(url, data=data)

print(response.json())

In this example, we are sending two parameters (name and price) with our request to the URL https://api.example.com/products. The values of these parameters are Samsung Galaxy S20 and 1000, respectively.

Conclusion

Sending parameters with your API requests is a common task in Python programming. In this post, we have explored how to send parameters using the params argument in Python Requests library. We have also looked at other ways to send parameters such as including them in the URL itself or using the data argument for POST requests.
