Is there a way to clear your printed text in python?
提问by Joel Madsen
I have wanted for a long time to find out how to clear something like print("example") in python, but I cant seem to find anyway or figure anything out.
很长一段时间以来，我一直想知道如何在 python 中清除类似 print("example") 之类的东西，但我似乎无法找到或弄清楚任何事情。
print("Hey")
>Hey
Now I need to clear it, and write some new text.
现在我需要清除它，并写一些新的文本。
print("How is your day?")
It would print.
它会打印。
Hey
嘿
>How is your day?
But I want to clear the "Hey" so the user shouldnt look at both at same time, and it looks kinda messy.
但我想清除“嘿”，所以用户不应该同时看这两个，而且看起来有点乱。

import os
os.system('cls')
Or os.system('clear')on unix (mac and linux). If you don't want the scroll up either, then you cando this:
或者os.system('clear')在 unix（mac 和 linux）上。如果您也不想向上滚动，则可以执行以下操作：
os.system("printf '\033c'")should get rid of scroll back too. Something that works on all systems:
os.system("printf '\033c'")也应该摆脱回滚。适用于所有系统的东西：
import os
os.system('cls' if os.name == 'nt' else "printf '3c'")

I think this is what you want to do:
我认为这就是你想要做的：
take the cursor one line up and delete the line
将光标向上移动一行并删除该行
this can be done like using the code below
这可以像使用下面的代码一样完成
import sys
import time
def delete_last_line():
"Use this function to delete the last line in the STDOUT"
#cursor up one line
sys.stdout.write('\x1b[1A')
#delete last line
sys.stdout.write('\x1b[2K')
########## FOR DEMO ################
if __name__ == "__main__":
print("hello")
print("this line will be delete after 2 seconds")
time.sleep(2)
delete_last_line()

Well; i have a temporary way:-
好; 我有一个临时的方法：-
print('Hey', end = '')
for i in range(4):
print('\b', end = '')
print('How is your day?')

import time
Dots = "."
total = 0
count = 0
while count < 5:
if total<1:
print("[+]Saving" + Dots,end="")
total+=1
time.sleep(1)
print(Dots,end="")
This code works perfectly fine...
这段代码工作得很好......
