I want to get user input in a python script after the script has begun, not as a command line argument.

I tried using pythons input method, but this behaves like a standard text-box. Is there an input type in python that behaves like the bash terminal with predictive suggestions and bash syntax such as file{1..7}

It would be helpful if you'd add which operating system you are using and for what purpose you want the 'bash-like' input. The most common way I guess would be to implement a CLI yourself and then calling the bash, but this may be a bit over the top depending on what you want to achieve.

For implementing a CLI I suggest to have a look at the click-package. Just a quick example:

import click

import click_repl

from subprocess import Popen, DEVNULL

import os

from prompt_toolkit.history import FileHistory



@click.group(invoke_without_command=True)

@click.pass_context

def cli(ctx):

    if ctx.invoked_subcommand is None:

        ctx.invoke(repl)



@cli.command()

@click.option("--directory", "-d", prompt=True, help="Directory to cd into")

def cd(directory):

    command = "cd {0}".format(directory)

    Popen(command, shell=True, stdin=None, stdout=DEVNULL, stderr=None)



@cli.command()

def repl():

prompt_kwargs = {

    'history': FileHistory(os.path.expanduser('~/.repl_history'))

}

click_repl.repl(click.get_current_context(), prompt_kwargs)



try:

    cli(obj={})

except SystemExit:

    pass

It is important to catch a SystemExit because click always throw one after executing a command. And you have to implement every bash command you want to allow as a click command.
