Type just one character not followed by ENTER

[sylas]

Hi all! If I remember well,in C++, I could wait an answer to (y/n), the user typing y, not followed by hitting ENTER. Is it possible in python3 ?? Thanks

Click also provides this as functionality http://click.pocoo.org/5/utils/#getting-...m-terminal

I think recently a noticed yet another one

I just had a post about getting keypress here.
So if i rewrite it a little.

import msvcrt

print('Would you like to go on y/n')
while True:
    ch = msvcrt.getch()
    if ch in b'\x00':
        ch = msvcrt.getch()
    if ch == b'y':
        print('<y> typed going out')
        break
    if ch == b'q':
       break
    else:
       print(f'Key Pressed: {ch}')

Test:

Output:
E:\div_code
λ python scan_user.py
Would you like to go on y/n
Key Pressed: b'n'
Key Pressed: b'g'
Key Pressed: b't'
Key Pressed: b'r'
Key Pressed: b'e'
<y> typed going out

This is Windows only,as @buran mention Click which is my favorite CLI tool for Python.
Click work cross platform and solve Unicode for all shell(even cmd Windows).
My tutorial about it.
See that i use b'y' to get it to work Python 3.

import click

click.echo('Continue? [yn] ', nl=False)
c = click.getchar()
click.echo()
if c == b'y':
    click.echo('We will go on')
elif c == b'n':
    click.echo('Abort!')
else:
    click.echo('Invalid input :(')

Test:

Output:
E:\div_code
λ python yn.py
Continue? [yn] # No Enter pressed
We will go on
