Title says it all, I need to log two strings in one line.
For example, something like this:
logging.info(string1,string2)
Thank you :)

The logging functions act like this:
result = arg1 % (arg2, arg3, ...)
What you have will try to format the first string with the second string:
result = string1 % string2
Either manually specify a formatting string:
logging.info('%s %s', string1, string2)
Or join them together into one string:
logging.info(' '.join([string1, string2]))

You forgot the simple case of
string1 + string2.You can use %-formatting, like this:
logging.info("%s %s", string1, string2)
For example:
>>> string1, string2 = "spam", "pie"
>>> logging.info("%s %s", string1, string2)
INFO: spam pie

>>> ( s1,s2 ) = ( 'apple','mango' );
>>> print( '{},{}'.format(s1,s2) );
apple,mango

Using f strings, you could turn this into a one-liner and make it quite readable.
# python3 f-strings
logging.info(f'{string1} {string2}')

Not a good practice to do so. For more details, check palkeo.com/en/blog/python-logging.html
logger.info("String 1: {0!r} --- String 2: {1!r}".format(string1, string2))
Demo:
>>> print "String 1: {0!r} --- String 2: {1!r}".format('hello', 'world')
String 1: 'hello' --- String 2: 'world'
>>> print "String 1: {1!r} --- String 2: {0!r}".format('world', 'hello')
String 1: 'hello' --- String 2: 'world'
Two things to note here:
- The number in {0!r} and {1!r} specify the argument you get from input.
- '!s' (apply str()) and '!r' (apply repr()) can be used to convert the value before it is formatted.
