请编写我的示例Python程序代码

Question

我还在学习Python,因为我想向十一岁的孩子讲授这门语言的基本概念(我是一名教师).我们在基础方面做了一些工作,因此他们了解编程的基本要素,并将任务分解成块等.Python是那将是所有教在英国新课程进来,我不想教孩子坏习惯的语言.下面是我写的一个小程序,是的,我知道它很糟糕,但任何有关改进的建议都会非常感激.

我仍在翻阅语言的教程,所以请保持温和!:O)

# This sets the condition of x for later use
x=0
# This is the main part of the program
def numtest():
    print ("I am the multiplication machine")
    print ("I can do amazing things!")
    c = input ("Give me a number, a really big number!")
    c=float(c)
    print ("The number", int(c), "multiplied by itself equals",(int(c*c)))
    print("I am Python 3. I am really cool at maths!")
    if (c*c)>10000:
        print ("Wow, you really did give me a big number!")
    else:
         print ("The number you gave me was a bit small though. I like bigger stuff than that!")

# This is the part of the program that causes it to run over and over again.
while x==0:
    numtest()
    again=input("Run again? y/n >>>")
    if x=="y":
        print("")
        numtest()
    else:
        print("Goodbye")

Answer 1

您似乎不需要变量 x

while True:
    numtest()
    again = input("Run again? y/n >>>")
    if again == "y":       # test "again", not "x"
        print("")
    else:
        print("Goodbye")
        break              # This will exit the while loop
