[ACCEPTED]-Python Interactive Shell Type Application-console-application
Just input the commands in a loop.
For parsing 4 the input, shlex.split is a nice option. Or just go 3 with plain str.split.
import readline
import shlex
print('Enter a command to do something, e.g. `create name price`.')
print('To get help, enter `help`.')
while True:
cmd, *args = shlex.split(input('> '))
if cmd=='exit':
break
elif cmd=='help':
print('...')
elif cmd=='create':
name, cost = args
cost = int(cost)
# ...
print('Created "{}", cost ${}'.format(name, cost))
# ...
else:
print('Unknown command: {}'.format(cmd))
The readline library adds history functionality 2 (up arrow) and more. Python interactive 1 shell uses it.
Another approach to building interactive 4 applications like this is by using the cmd module.
# app.py
from cmd import Cmd
class MyCmd(Cmd):
prompt = "> "
def do_create(self, args):
name, cost = args.rsplit(" ", 1) # args is string of input after create
print('Created "{}", cost ${}'.format(name, cost))
def do_del(self, name):
print('Deleted {}'.format(name))
def do_exit(self, args):
raise SystemExit()
if __name__ == "__main__":
app = MyCmd()
app.cmdloop('Enter a command to do something. eg `create name price`.')
And 3 here is the output of running the above 2 code (if the above code was in a file named 1 app.py):
$ python app.py
Enter a command to do something. eg `create name price`.
> create item1 10
Created "item1", cost $10
> del item1
Deleted item1
> exit
$
You could start by having a look at argparse.
It 3 does not provide a complete interactive 2 shell, like you ask, but it helps in creating 1 functionality similar to your PHP example.
