使用 Python 下载 mp3 文件时遇到问题

Question

我是编码新手，曾一度尝试下载 mp3 文件。我可以访问该文件但不能下载它；执行这段代码的下载mp3文件部分会产生各种问题。拜托，你能帮帮我吗？我将 MAC 平台与 PyCharm.

一起使用

代码从这里开始

import os
from selenium import webdriver
from selenium.webdriver.chrome.webdriver import WebDriver
import urllib.request

示例音频 URL

url = 'https://file-examples-com.github.io/uploads/2017/11/file_example_MP3_700KB.mp3'
path = os.path.abspath(os.getcwd())

正在创建网络驱动程序

options = webdriver.ChromeOptions()
driver: WebDriver = webdriver.Chrome(options=options, executable_path='/Users/sam/Downloads/chromedriver')
driver.get(url)

获取 mp3 音频文件

src = driver.find_element_by_xpath("/html/body/video/source").get_attribute("src")
print("[Audio File Path:] ",src)

正在下载 mp3 文件

urllib.request.urlretrieve(src, path+"//sample.mp3")

#------------代码结束-------------

错误
