How to use Python Requests

Python Requests is a popular library used for making HTTP requests in Python. It is a simple and easy-to-use library that allows you to send HTTP/1.1 requests using Python.

Installation

You can install Requests using pip, the package installer for Python.

pip install requests

Sending a GET Request

Sending a GET request using Requests is as easy as calling the get() method and passing the URL.

import requests

response = requests.get('https://jsonplaceholder.typicode.com/posts')

print(response.status_code)
print(response.content)

In the above example, we are sending a GET request to https://jsonplaceholder.typicode.com/posts.

  • We import the Requests library using the import statement.
  • We then call the get() method and pass the URL as an argument.
  • The get() method returns a response object which we store in the response variable.
  • We can then access the response status code using the status_code attribute of the response object.
  • We can also access the content of the response using the content attribute of the response object.

Sending a POST Request

To send a POST request, we can use the post() method and pass the URL and data.

import requests

data = {
    'username': 'john',
    'password': 'password123'
}

response = requests.post('https://jsonplaceholder.typicode.com/posts', data=data)

print(response.status_code)
print(response.content)

In the above example, we are sending a POST request to https://jsonplaceholder.typicode.com/posts with some data.

  • We create a dictionary called data with some key-value pairs.
  • We then call the post() method and pass the URL and the data dictionary as arguments.
  • The post() method returns a response object which we store in the response variable.
  • We can then access the response status code using the status_code attribute of the response object.
  • We can also access the content of the response using the content attribute of the response object.

Sending a PUT Request

To send a PUT request, we can use the put() method and pass the URL and data.

import requests

data = {
    'title': 'foo',
    'body': 'bar',
    'userId': 1
}

response = requests.put('https://jsonplaceholder.typicode.com/posts/1', data=data)

print(response.status_code)
print(response.content)

In the above example, we are sending a PUT request to https://jsonplaceholder.typicode.com/posts/1 with some data.

  • We create a dictionary called data with some key-value pairs.
  • We then call the put() method and pass the URL and the data dictionary as arguments.
  • The put() method returns a response object which we store in the response variable.
  • We can then access the response status code using the status_code attribute of the response object.
  • We can also access the content of the response using the content attribute of the response object.

Sending a DELETE Request

To send a DELETE request, we can use the delete() method and pass the URL.

import requests

response = requests.delete('https://jsonplaceholder.typicode.com/posts/1')

print(response.status_code)
print(response.content)

In the above example, we are sending a DELETE request to https://jsonplaceholder.typicode.com/posts/1.

  • We call the delete() method and pass the URL as an argument.
  • The delete() method returns a response object which we store in the response variable.
  • We can then access the response status code using the status_code attribute of the response object.
  • We can also access the content of the response using the content attribute of the response object.

Error Handling

Requests also provides error handling for HTTP errors. If a request returns an error status code (400 or above), Requests will raise an exception.

import requests

try:
    response = requests.get('https://jsonplaceholder.typicode.com/invalid')
    response.raise_for_status()
except requests.exceptions.HTTPError as err:
    print(err)

In the above example, we are sending a GET request to an invalid URL. Requests will raise a HTTPError exception, which we catch and print the error message.

Conclusion

Python Requests is a simple and easy-to-use library for making HTTP requests in Python. It provides methods for sending GET, POST, PUT and DELETE requests, as well as error handling for HTTP errors. With Python Requests, you can easily interact with APIs and web services.
