requests library in Python can be used to send http get request (e.g. download an image), pass an argument to the request, perform post request
Using GET request
You can retrieve the data from specific resource by using request.get('url') which returns response object.
import requests
r = requests.get('http://url-to-your-resource')
Downloading and saving an image
import requests
resp = requests.get('https://imgs.xkcd.com/comics/making_progress.png)
with open('e:\prakash\temp\image.png', 'wb') as f:
f.write(resp.content)
Using POST request
import requests
pload = {'username':'Olivia','password':'123'}
r = requests.post('https://httpbin.org/post',data = pload)
print(r.text)
