Python: Verify SSL certificates for HTTPS requests

Python Requests: Exercise-9 with Solution

Write a Python code to verify the SSL certificate for a website which is certified.

Sample Solution:

Python Code:

import requests   
#Requests ignore verifying the SSL certificate if you set verify to False
# Making a get request 
response = requests.get('https://rigaux.org/', verify=False)
print(response) 
print("\n=======================================================\n")
#Requests verifies SSL certificates for HTTPS requests, just like a web browser.
response1 = requests.get('https://google.com/')
print(response1)
print("\n=======================================================\n")
#Requests ignore verifying the SSL certificate if you set verify to True (Default value)
response1 = requests.get('https://rigaux.org/', verify=True)
print(response1) 

Sample Output:

D:\Anaconda3\lib\site-packages\urllib3\connectionpool.py:847: InsecureRequestWarning: Unverified HTTPS request is being made. Adding certificate verification is strongly advised. See: https://urllib3.readthedocs.io/en/latest/advanced-usage.html#ssl-warnings
  InsecureRequestWarning)
<Response [200]>

<Response [200]>

Merging two dicts in Python 3.5+ with a single expression

Example:

# How to merge two dictionaries
# in Python 3.5+

x = {'p': 1, 'q': 3}
y = {'q': 5, 'r': 8}

z = {**x, **y}

z
{'r': 4, 'p': 1, 'q': 3}

z = dict(x, **y)
print(z)

Output:
