以下是一个简单的Python计算器程序:
num1 = float(input("请输入第一个数字:"))
op = input("请输入运算符(+、-、*、/):")
num2 = float(input("请输入第二个数字:"))
if op == "+":
print(num1 + num2)
elif op == "-":
print(num1 - num2)
elif op == "*":
print(num1 * num2)
elif op == "/":
print(num1 / num2)
else:
print("无效的运算符")

def subtract(x, y):
return x - y
def multiply(x, y):
return x * y
def divide(x, y):
return x / y
print("选择运算:")
print("1、相加")

print("3、相乘")
print("4、相除")
choice = input("输入你的选择(1/2/3/4):")
num1 = float(input("输入第一个数字: "))
num2 = float(input("输入第二个数字: "))
if choice == '1':
print(num1,"+",num2,"=", add(num1,num2))
elif choice == '2':
print(num1,"-",num2,"=", subtract(num1,num2))
elif choice == '3':
print(num1,"*",num2,"=", multiply(num1,num2))
elif choice == '4':
