requests庫時，設定代理的方法：

import requests

proxy = '127.0.0.1:9743'

proxies = {
    'http': 'http://' + proxy,
    'https': 'https://' + proxy,
}
try:
    response = requests.get('http://httpbin.org/get', proxies=proxies)
    print(response.text)
except requests.exceptions.ConnectionError as e:
    print('Error', e.args)
 

selenium 模組時，以Chrome瀏覽器為例：

from selenium import webdriver

proxy = '127.0.0.1:9743'
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument('--proxy-server=http://' + proxy)
chrome = webdriver.Chrome(chrome_options=chrome_options)
chrome.get('http://httpbin.org/get')

selenium 模組時，以phantomJS瀏覽器為例：

from selenium import webdriver

service_args = [
    '--proxy=127.0.0.1:9743',
    '--proxy-type=http'
]

browser = webdriver.PhantomJS(service_args=service_args)
browser.get('http://httpbin.org/get')
print(browser.page_source)
