Python: Raise Timeout exception in the event of times out of request
Python Requests: Exercise-6 with Solution
Write a Python code to send a request to a web page and stop waiting for a response after a given number of seconds. In the event of times out of request, raise Timeout exception.
Sample Solution:
Python Code:
import requests
print("timeout = 0.001")
try:
r = requests.get('https://github.com/', timeout = 0.001)
print(r.text)
except requests.exceptions.RequestException as e:
print(e)
print("\ntimeout = 1.0")
try:
r = requests.get('https://github.com/', timeout = 1.0)
print("Connected....!")
except requests.exceptions.RequestException as e:
print(e)
Sample Output:
timeout = 0.001 HTTPSConnectionPool(host='github.com', port=443): Max retries exceeded with url: / (Caused by ConnectTimeoutError(<urllib3.connection.VerifiedHTTPSConnection object at 0x0BD7B0D0>, 'Connection to github.com timed out. (connect timeout=0.001)')) timeout = 1.0 Connected....!

Python: Tips of the Day
Find current directory and file's directory:
To get the full path to the directory a Python file is contained in, write this in that file:
import os dir_path = os.path.dirname(os.path.realpath(__file__))
(Note that the incantation above won't work if you've already used os.chdir() to change your current working directory, since the value of the __file__ constant is relative to the current working directory and is not changed by an os.chdir() call.)
To get the current working directory use
import os cwd = os.getcwd()
Documentation references for the modules, constants and functions used above:
- The os and os.path modules.
- The __file__ constant
- os.path.realpath(path) (returns "the canonical path of the specified filename, eliminating any symbolic links encountered in the path")
- os.path.dirname(path) (returns "the directory name of pathname path")
- os.getcwd() (returns "a string representing the current working directory")
- os.chdir(path) ("change the current working directory to path")
