Python计算器程序【加减乘除操作】
a = float(input(“请输入第一个数：”))
b = input(“请输入运算符：”)
c = float(input(“请输入第二个数：”))
d = a + c
e = a - c
f = a * c
g = a / c
h = “+”
i = “-”
j = “*”
k = “/”
if h == b:
print(“结果是%s”%d)
elif i == b:
print(“结果是%s”%e)
elif j == b:
print(“结果是%s”%f)
elif k == b:
print(“结果是%s”%g)
else:
print(“输入错误，请重新输入”)
举例输出：
