更新多条输出线

Question

So I am trying to use sys.stdout.write() to rewrite the current line it is on and replace it with different text. But I want this to happen for multiple lines of output.

  # I am looking at having 2 lines with changing values in them that will keep over writing themselves without moving any further down.
  import sys
  for i in range(10):
       sys.stdout.write("\r" + "Hello" + str(i) + "\n + "Hello" + str(i) * 2)
       sys.stdout.flush()

I tried this but every time it hits the \\n it will indefinately increase the numbers of lines without clearing everything.

Answer 1

stdout\\stderr don't work like that. You can send control characters to your terminal to delete characters but once a line is sent it's basically fixed.

What you actually need is ncurses which gives you much more control over the display and cursor position when writing to a terminal.
