How do I put a variable inside a string?

Question

I would like to put an int into a string. This is what I am doing at the moment:

num = 40
plot.savefig(\'hanning40.pdf\') #problem

In general, you can create strings using:

stringExample = "someString " + str(someNumber)
print(stringExample)
plot.savefig(stringExample)
