如何使用 python 和 cmd 删除和替换多条打印线？ [等候接听]

Question

I tried to run this code:

hello = """  _    _ 
 | |  | |
 | |__| |
 |  __  |
 | |  | |
 |_|  |_|"""

for char in range(len(hello)):
    print (hello[:char])
    time.sleep(0.05)

I wanted to delete everything that was printed in the end of each iteration. I tried to use print (hello[:char], end="\r") but it didn't seem to do the job.

(Stack overflow won't let me share the output, It's too long. The output I got was a character added in each iteration, but in a new printed line)

Thanks a lot!

Try this:

for char in range(len(hello)): 
    print (hello[:char], end='\r')
    time.sleep(0.05) 

Instead of using raw r , use special character \r - called carriage return.
