python에서 line 줄바꿈없이 업데이트하기

파이썬에서 print로 출력할 때, 줄바꿈 없이 print 내용이 업데이트하는 방법이다. 

출처는 역시 스택오버플로우~!

t's called the carriage return, or \r

Use

print i/len(some_list)*100," percent complete         \r",

The comma prevents print from adding a newline. (and the spaces will keep the line clear from prior output)

Also, don't forget to terminate with a print "" to get at least a finalizing newline!
