Windows - Need to process quotes in string...

[Ernesto]

I'm trying to use a $ delimeter, but it doesn't seem to work. Here is
the code:


launchWithoutConsole("devcon.exe",d'$enable
"@USB\VID_0403&PID_6010&MI_00\7&15E4F68&1&0000"$)

I want to send the string parameter:

enable "@USB\VID_0403&PID_6010&MI_00\7&15E4F68&1&0000"

to the program devcon.

The argument itself is a string, but has quotes inside too. I've tried
it many different ways and I keep getting syntax errors.

Thanks,

Why?

I want to send the string parameter:

enable "@USB\VID_0403&PID_6010&MI_00\7&15E4F68&1&0000"

launchWithoutConsole("devcon.exe"
'enable "@USB\VID_0403&PID_6010&MI_00\7&15E4F68&1&0000"')

Or, if you should also be able to send single quotes:

launchWithoutConsole("devcon.exe"
'''enable "@USB\VID_0403&PID_6010&MI_00\7&15E4F68&1&0000"''')

The argument itself is a string, but has quotes inside too.

Then use other quotes as string delimiters. Why would you use
something else?

Use the single quote to delimit the string, so you can use the double
quote inside it. Like this:

'enable "@USB\VID_0403&PID_6010&MI_00\7&15E4F68&1&0000"'

Ernesto enlightened us with:
Where did you get the idea that this would work? I can't find any
references to a "customizable string delimiter" in any Python up through
2.4.2. I recall it being proposed at one point, but I don't think it was
ever seriously considered.

launchWithoutConsole("devcon.exe",
'enable "@USB\VID_0403&PID_6010&MI_00\7&15E4F68&1&0000"')

This is not correct. It might accidentally work because \V is not a
defined escape sequence, but the right answer is either:

launchWithoutConsole("devcon.exe",
'enable "@USB\\VID_0403&PID_6010&MI_00\\7&15E4F68&1&0000"')

or

launchWithoutConsole("devcon.exe",
r'enable "@USB\VID_0403&PID_6010&MI_00\7&15E4F68&1&0000"')

However, devcon.exe supports regular expressions, and is forgiving about
syntax. If you have only one such device, you could use:

launchWithoutConsole("devcon.exe",
r'enable "@USB\VID_0403&PID_6010*"')
