InputConsole

InputConsole is a console for Python that will keep all output above the input line without interrupting the input line.

$ pip3 install inputconsole

Example

from inputconsole import InputConsole

# Create the console
console = InputConsole()

# Register a command
def help(args):
    console.write("I don't want to help you {0}.\n".format(args[0]))
console.register_command('help', help)

# Set unknown command handler, Return 'True' for command handled or
# 'False' for command not handled.
def unknown_command_handler(command):
    console.write("Unknown command: " + command)
    return True
console.set_unknown_command_handler(unknown_command_handler)

# Start listening for input on a new thread
# Input line will always stay at the bottom
console.listen_for_input()

# Generate random output to keep the output thread active.
def steady_flow():
    num = 0
    while True:
        console.write("this is an output message: {0}\n".format(num))
        time.sleep(2)
        num += 1
t = Thread(target=steady_flow)
t.start()
t.join()
