【作品介绍】

海龟编辑器可以发布作品啦！！！

心情大喜，制作了个计算器！！！

（训练师做数学题时建议使用······）

 

【作品源代码】

def add(a, b):

    return (a + b)

def subtract(a, b):

    return (a - b)

def multiply(a, b):

    return (a * b)

def divide(a, b):

    return (a / b)

def power(a, b):

    return (a ** b)

num1 = float(input('你好，训练师，请输入第一个数字：'))
num2 = float(input('再输入第二个数字：'))

print('选着要进行的运算：')

print('1.相加 2.相减 3.相乘 4.相除 5.乘方')

choice = input('输入你的选择:(1/2/3/4/5)')

result = 0

if (choice == '1'):
    result = add(num1, num2)
    print(num1, '+', num2, '=', result)
if (choice == '2'):
    result = subtract(num1, num2)
    print(num1, '-', num2, '=', result)
if (choice == '3'):
    result = multiply(num1, num2)
    print(num1, '*', num2, '=', result)
if (choice == '4'):
    result = divide(num1, num2)
    print(num1, '/', num2, '=', result)
if (choice == '5'):
    result = power(num1, num2)
    print(num1, '**', num2, '=', result)

if (result > 100):
    print('计算结果大于100！')
