Python下载单词音频在Ubuntu下失败

最近在学英语,用anki整理了自己不会的单词,想添加一点单词音频,于是从网上找了一个模板代码,但是由于原代码是win环境下的,自用的ubuntu不起作用,所以修改了一下,但是,修改之后,还是出错,本人业余,希望大家指点一下:
在终端运行,显示错误代码为

lic@DELL:~/Desktop$ python english.py
Traceback (most recent call last):

    main()
  File "english.py", line 75, in main
    workerNumber=int(sys.argv[1])

麻烦浪费您30秒,贴一下具体是什么错误?

大体看了下，这个脚本运行时需要接收两个参数，第一个是开启下载线程的数量，第二个是单词文件的路径，所以尝试下

python english.py 1 单词文件的路径

单词文件的格式为每个单词占一行

这段代码写的很清楚，最好先看明白再使用
