Python - 隐藏已打印的文本[重复]

Question

我对基本的简单 python 有疑问。所以我正在做一个记忆游戏，我想显示对象，延迟 5 秒后，让文本消失。

import time

print("Welcome to the memory game.")
print("Choose difficulty level :")
print("1. Easy")
print("2. Medium")
print("3. Hard")
print("4. Very Hard")
x = input("press '1' for easy, '2' for medium, '3' for hard and '4' for very hard :  ")

if x == '1' :
    print("You chose level 1, easy.")
    print("I will give you 3 objects and you have to type then in the correct order to gain points.")
    print("Not cAsE SeNSitIvE")
    obj = print("Ship, Money, Python")
    time.sleep(5)
    ez = input().upper
    if ez == 'Ship, Money, Python' or ez == 'ship,money,python' or ez == 'Ship,Money,Python' or ez == 'ship, money, python' :
        print("Correct")
    else :
        print("Wrong")
        print("The answer was : Ship, Money, Python")

这是代码的一部分。请帮我在这里????我想隐藏文字 obj = print("Ship, Money, Python") 延迟 5 秒后。

Answer 1

以"\r" 结尾会导致下一个输出从上一行的开头开始。然后，您可以将输出替换为适当数量的空格 (" " * len(text))。

# import time

print("Welcome to the memory game.")
print("Choose difficulty level :")
print("1. Easy")
print("2. Medium")
print("3. Hard")
print("4. Very Hard")
x = input("press '1' for easy, '2' for medium, '3' for hard and '4' for very hard :  ")

if x == '1' :
    print("You chose level 1, easy.")
    print("I will give you 3 objects and you have to type then in the correct order to gain points.")
    print("Not cAsE SeNSitIvE")
    text = "Ship, Money, Python"
    obj = print(text, end="\r")
    time.sleep(1)
    print(" " * len(text), end="\r")
    ez = input().upper()
    if ez in [string.upper() for string in 
              ['Ship, Money, Python',
               'ship,money,python',
               'Ship,Money,Python', 
               'ship, money, python']]:
        print("Correct")
    else :
        print("Wrong")
        print("The answer was : Ship, Money, Python")

编辑：已简化您的检查以打印输入的正确性。

试试这个：

import time
import re

print("Welcome to the memory game.")
print("Choose difficulty level :")
print("1. Easy")
print("2. Medium")
print("3. Hard")
print("4. Very Hard")
x = input("press '1' for easy, '2' for medium, '3' for hard and '4' for very hard :  ")

if x == '1' :
    print("You chose level 1, easy.")
    print("I will give you 3 objects and you have to type then in the correct order to gain points.")
    print("Not cAsE SeNSitIvE")
    text = "Ship, Money, Python"
    obj = print(text, end="\r")
    time.sleep(5)
    print(" " * len(text))

    ez = str(input()).upper()
    if re.match(r"SHIP\s*,\s*MONEY\s*,\s*PYTHON", ez):
        print("Correct")
    else :
        print("Wrong")
        print("The answer was : Ship, Money, Python")

Answer 3

这是一个可行的解决方案。它使用\r 回到行首，\033[K 清除行：

import time

print("Welcome to the memory game.")
print("Choose difficulty level :")
print("1. Easy")
print("2. Medium")
print("3. Hard")
print("4. Very Hard")
x = input("press '1' for easy, '2' for medium, '3' for hard and '4' for very hard :  ")

if x == '1' :
    print("You chose level 1, easy.")
    print("I will give you 3 objects and you have to type then in the correct order to gain points.")
    print("Not cAsE SeNSitIvE")
    obj = print("Ship, Money, Python", end='\r', flush=True)
    time.sleep(5)
    print('\033[K', end='', flush=True)
    ez = input().upper
    if ez == 'Ship, Money, Python' or ez == 'ship,money,python' or ez == 'Ship,Money,Python' or ez == 'ship, money, python' :
        print("Correct")
    else :
        print("Wrong")
        print("The answer was : Ship, Money, Python")

如何使用显示句子的缓冲区。

这是一种想法。你可以修改一些代码行。

import os
import time

buffer = [
    "Welcome to the memory game.",
    "Choose difficulty level :",
    "1. Easy",
    "2. Medium",
    "3. Hard",
    "4. Very Hard",
    "press '1' for easy, '2' for medium, '3' for hard and '4' for very hard :  ",
]


def printing():
    os.system('clear')
    for line in buffer:
        print(line)


printing()
x = input()

if x == '1':
    buffer.append("You chose level 1, easy.")
    buffer.append("I will give you 3 objects and you have to type then in the correct order to gain points.")
    buffer.append("Not cAsE SeNSitIvE")
    printing()
    print("Ship, Money, Python")
    time.sleep(5)
    printing()
    ez = input()
    if ez == 'Ship, Money, Python' or ez == 'ship,money,python' or ez == 'Ship,Money,Python' or ez == 'ship, money, python':
        print("Correct")
    else:
        print("Wrong")
        print("The answer was : Ship, Money, Python")

编辑： 如果您收到“未设置 TERM 环境变量”的警告语句，则应检查终端的值 TERM。

例如）$ export TERM=xterm
