z = raw_input("Is your age %d') %(var)

but this don't work. Any ideas?

回答1:

With raw_input, %var should also lie within the parentheses. i.e:

z = raw_input("Is your age %d" % var)

回答2:

I guess the cleanest way is to use format:

z = raw_input("Is your age {0}?".format(var))

Your code should be:

z = raw_input("Is your age %d" %(var,) )
