Symbian app on Python note usage

Question

When I try to use this command

appuifw.note(u"Connecting to %s" % (address), "conf");

I'm getting error: "not all arguments converted during string formatting"

How to fix this error?

Answer 1

The error you mentioned arise in cases like

>>> print "my name is %s" %('foo','bar')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: not all arguments converted during string formatting

It means I have 2 values to replace ('foo', 'bar') but only provided one place holder (%s).

To correct it

>>> print "my name is %s %s" %('foo','bar')
    my name is foo bar

There is also a another way to achieve this using str.format().

>>> print "my name is {0} {1}".format('foo','bar')
    my name is foo bar

Answer 2

There is another option with dictionaries

mydict = {'foo': 'bar', 'foo2': 'bar2'}
print "my name is %(foo)s" % mydict

this way you can use only foo if you want.

Note the last 's' is for 'string', so if you add something like %(foo)d it means %d with name foo.
