嵌套if else的更好方法

Question

如何以更好的方式完成嵌套if else？我想最小化代码重复print "run dozer()"

print "some mechanical stuffs before this"
if a == 1:
    if b == 2:
        print "run car()"
    else:
        print "run dozer()"
else:
    print "run dozer()"
print "more mechanical stuffs after this"

Answer 1

if a == 1 and b == 2:
    print "run car()"
else:
    print "run dozer()"
