Window Console Problems

1. On windows the script keeps printing the process bar

Different reasons for different windows. On windows 10 default console(cmd.exe) the Unicode characters used in the process bar takes 2-character space. Not sure changing the font for the console can fix it or not.

You can test this with the following script:

print('_' * 80)
print('├' * 80)
print('█' * 80)
print('┤' * 80)

The script does print 80 characters but it takes spaces for 160 characters in the last three statements. A '\r' cannot move to the last printed line so it will keep printing the process bar.

Solution: Perhaps you can switch to a better console emulator, cmder for instance.

2. How to tell you-get the correct URL

F.I. the URL is http://www.icourses.cn/jpk/changeforVideo.action?resId=722918&courseId=5929&firstShowFlag=2

you-get http://www.icourses.cn/jpk/changeforVideo.action?resId=722918&courseId=5929&firstShowFlag=2

won't work. What you-get received is http://www.icourses.cn/jpk/changeforVideo.action?resId=722918 You have to quote the URL like

you-get "http://www.icourses.cn/jpk/changeforVideo.action?resId=722918&courseId=5929&firstShowFlag=2" 

NOTE: On the homepage URLs are single quoted, which won't work with cmd.exe.
