x,y,z=2,-1,2;

If x<y:

   If y<0:

      z=0

   else:

      z+=1

print(z)

print(0.1+0.2==0.3)

while not E:

pass

Result=sum(num1, num2, num3)

age =input(“please input your age:")

if age>=18:

print("已成年!”)

else:

print("未成年!")

   print(a,b,c)

Sum(8,2)

运行结果是:

s=['a','b']

s. append([1. 2])

s.insert(1.7):

执行以上代码后，s值为（）
