python计算器简单代码

当创建一个简单的 Python 计算器时，你可以使用基本的数学运算符和用户输入。

python
def add(x, y):

return x + y

def subtract(x, y):

return x - y
def multiply(x, y):

return x * y
def divide(x, y):

if y != 0:

return x / y

else:

return "Error: Cannot divide by zero."
while True:

# 获取用户输入

num1 = float(input("请输入第一个数字: "))

operator = input("请输入运算符 (+, -, *, /): ")

num2 = float(input("请输入第二个数字: "))
    # 执行计算

if operator == "+":

result = add(num1, num2)

elif operator == "-":

result = subtract(num1, num2)

elif operator == "*":

result = multiply(num1, num2)

elif operator == "/":

result = divide(num1, num2)

else:

print("无效的运算符")

continue
    # 显示结果

print("结果: ", result)
    # 询问用户是否
如果你想扩展这个简单计算器的功能，可以考虑添加其他数学运算或改进用户界面。例如，你可以添加取余数、幂运算等功能，或者使用图形用户界面库来创建更友好的计算器界面。

else:

def modulus(x, y):
