it is not difficult at all
instead of using " to embrace your global string, you can also use the single '
so you can use the command
print 'He said,"Hello".'
and for this : "I finished my first course!".
in the same way
the single ' embraces the string that you want to print
print '"I finished my first course!"'
Also you could "escape" them by using
"Here comes a quote: \"quote\""
