if else statement error

[mooninite]

Hi there,

Let me start off saying I'm a C programmer, and that Python is a new language for me.

I'm trying to write an if statement, which works under Python 2.5 on my Fedora machine, but S60 Python says it is an error. The code in question:

            elif 'SEARCHING' in data:
                print 'received SEARCHING: resending command'
                self._send_command(cmd, ret_cb, err_cb, args)

The error from S60 Python:

line 470, in _parse_result
    elif 'SEARCHING' in data:
TypeError: 'in <string>' requires character as left operand

hi moonnite
actually your elif statement seems to be ok if "searching" is a string and if it is in the function data.
i think there must be a error in the other parts of your program like data.
Other wise the statement is pitty correct.

OK,

'SEARCHING' is a string, and data is a string.

I'm going to try some prints on data and make sure it contains a string and isn't coming through as NULL (or None I guess in Python). Would that cause this error?

Thanks


edit: I'm getting a string into "data" but I think it has some carriage returns in the first part of the string. Could this confuse S60 python?

Hi mooninite
you are the getting error becoz before the in statement there can be a character not a string.
Hope you got it now.

Thanks, I'll switch it to data.find('SEARCHING') != -1 instead.

Hi mooninite
that will be a good option.
