Assume I have a file at <http://mysite.com/myscript.sh> that contains:

```
#!/bin/bash
echo "Hello $1"

```

From the command line, I can execute my script (without downloading it) using the following command:

```
bash <(curl -s http://mysite.com/myscript.sh) World

```

Now, instead of executing the above command from the command line, I want to execute it from a python script. I tried doing the following:

```
import os
os.system('bash <(curl -s http://mysite.com/myscript.sh) World')

```

...but I get the following error:

> 
> sh: -c: line 0: syntax error near unexpected token `('
> 
> 
> 

How do I make this execute correctly in python?
