how to change the position of the cursor in python 3

Question

I am on windows 10 and I prefer not to install a new module (standard library solutions are accepted). I want the text that the user enters to start at the end of the third line.

My code:

print(" Enter password to unlock the Safe .\n\n password : \n\n\t2 attempts remaining .")
# code to move the cursor to the end of " password : " goes here
x = input()

output:

wanted output:

Also ANSI escape sequences don't seem to work without colorama(which unfortunately is an external module).

On Windows 10 you can use ANSI escape sequences as found in Console Virtual Terminal Sequences.

Before using them you need subprocess.run('', shell=True) (prior to Python 3.5, use subprocess.call). These sequences make possible what you are looking for.

Caution: Also original Microsoft, the documentation of Erase in Display and Erase in Line is partly faulty. The parameters 1 and 2 are reversed.

This should work (although, actually entering the password seems to destroy the layout):

import subprocess
subprocess.run('', shell=True)
print(' enter password : \0337', end='')
print('\n\n\t2 attempts remaining .\0338', end='')
x = input()

Could you give an example like an implementation of that on the code i posted? – Nick Ven Jun 03 '18 at 20:36
@nickven To use Warner's code you need to import the subprocess module. I can't test it myself, though, because I don't run Windows. – PM 2Ring Jun 03 '18 at 22:59
yeah now it works, thanks a lot. I must have typed it wrong the first time :) – Nick Ven Jun 03 '18 at 23:20
Why `subprocess.run("")`? What kind of sorcery is this? – Bharel Aug 13 '22 at 08:40

With Python 3 use;

print("...", end="")

i've tried that, it makes the cursor go at the end of the last line – Nick Ven Jun 03 '18 at 14:56
Try this: import sys sys.stdout.write("enter: ") – Yunus Jun 03 '18 at 15:00
You want to go first line. See this: https://stackoverflow.com/questions/27612545/how-to-change-the-location-of-the-pointer-in-python – Yunus Jun 03 '18 at 15:14
