Python - Hide already printed text

Question

I have a problem with basic simple python. So I am making a memory game and I want to display the objects and after a delay of 5 seconds, make the text disappear.

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")

this is a part of the code. Pls help me out here I want to hide the text obj = print("Ship, Money, Python") after a delay of 5 seconds.

If you want to clear the text from the terminal, you could sleep for 5 and then use a clear command. os.system('cls' if os.name == 'nt' else 'clear') You'll have to import os and sleep — pudup, Sep 08 '21 at 07:15

Ending with "\r" causes the next output to start at the beginning of the previous line. Then you can replace the output with an appropriate number of spaces (" " * 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")

Hey, let me check and get back to u, give me a minute – TrexS. Sep 08 '21 at 07:20
No, it's not solving the problem – TrexS. Sep 08 '21 at 07:23
The code hides perfectly, but even on typing the correct answer, it says "Wrong" "The correct answer was..." – TrexS. Sep 08 '21 at 07:23
That's a different problem. Please check what `input().upper()` looks like (you are missing brackets there, since upper is a function) and think about whether your comparison makes sense – mcsoini Sep 08 '21 at 07:27
Small update: use `end="\r"` also for the spaces to avoid newlines – mcsoini Sep 08 '21 at 07:30
@TrexS. Here is the full version, which also fixes your additional comparison issue – mcsoini Sep 08 '21 at 07:37
This works, too. Thank you – TrexS. Sep 08 '21 at 07:45

EDIT: have simplified your check to print correctness of the input.

Try out this:

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")

ok let me try that – TrexS. Sep 08 '21 at 07:24
No, there are 2 problems 1) Clears ALL THE code, all the text – TrexS. Sep 08 '21 at 07:26
2) It still says 'wrong' 'the correct answer was..' – TrexS. Sep 08 '21 at 07:26
What was the input given? – Bhagyesh Dudhediya Sep 08 '21 at 07:27
lemme try the edit – TrexS. Sep 08 '21 at 07:28
Hey, man, this code worked but it has one problem, all the text on the screen gets cleared. I just want the line 'obj = ("Ship, Money, Python")' to get hidden – TrexS. Sep 08 '21 at 07:30
@TrexS. Try the newly edited code, it gives you the intended results – Bhagyesh Dudhediya Sep 08 '21 at 07:31
It worked, thanks a lot friend. The code is now functioning correctly – TrexS. Sep 08 '21 at 07:36
Cools, can you pls accept it then? – Bhagyesh Dudhediya Sep 08 '21 at 07:36
I can't upvote, i dont have reputation, im new – TrexS. Sep 08 '21 at 07:37
No problem! Thanks for accepting it! Happy Coding – Bhagyesh Dudhediya Sep 08 '21 at 07:38
Hey, can u explain what u did, so it worked. I did not understand the logic – TrexS. Sep 08 '21 at 07:41
We just hide the text using `print (" "*len(text))`, `\r` in the `print (text, end=\r)` brings the cursor back to start point of the line and hence was hidden after 5 seconds. Then using python regex we made sure that the input from the user matches the one which we expect.

Here is a working solution. It uses \r to come back at the beginning of the line and \033[K to clear the line:

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")

It says wrong even thought I types it correctly – TrexS. Sep 08 '21 at 07:33 — TrexS., Sep 08 '21 at 07:33

How about to use buffer of showing sentences.

This is one of idea. you can modify some code lines.

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")

Edit: if you got an warning sentence that is "TERM environment variable not set.", then you should check the value TERM of your terminal.

ex) $ export TERM=xterm

let me check, doesn't work, my friend – TrexS. Sep 08 '21 at 07:34
Does it mean that "doesn't work" is an if statement? or printing function? – SEUNGFWANI Sep 08 '21 at 07:40
You should change your if statement on your code. Because this question's point is "how to hide already printed sentence" – SEUNGFWANI Sep 08 '21 at 07:43
I do not understand what u are trying to say...See, doesn't work means that the code u gave me doesn't function properly – TrexS. Sep 08 '21 at 07:47
Uhmm... how about set environment of your terminal before running. like `export TERM=xterm`. And if you use PyCharm, then you can try to check an option (`Emulate terminal in output console`) in `Debug configurations`. – SEUNGFWANI Sep 08 '21 at 07:55
