用python写一个计算器的代码

# 这是一个简单的python计算器代码：# 定义函数
def calculator(x, y):
'''
这是一个用来计算两个数字的函数
'''
# 加
add = x + y
# 减
sub = x - y
# 乘
mul = x * y
# 除
div = x / y
# 返回结果
return add, sub, mul, div

# 获取用户输入
x = float(input("请输入第一个数字："))
y = float(input("请输入第二个数字："))

# 调用函数
add, sub, mul, div = calculator(x, y)

# 输出结果
print("{0} + {1} = {2}".format(x, y, add))
print("{0} - {1} = {2}".format(x, y, sub))
print("{0} * {1} = {2}".format(x, y, mul))
print("{0} / {1} = {2}".format(x, y, div))

用python写一个计算器代码

以下是一个简单的Python计算器代码：

# Python计算器代码

# 加法函数
def add(x, y):
    return x + y

# 减法函数
def subtract(x, y):
    return x - y

# 乘法函数
def multiply(x, y):
    return x * y

# 除法函数
def divide(x, y):
    return x / y

print("请选择操作.")
print("1.加")
print("2.减")
print("3.乘")
print("4.除")

# 获取用户输入
choice = input("请选择操作（1/2/3/4）:")

num1 = int(input("请输入第一个数字: "))
num2 = int(input("请输入第二个数字: "))

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':
    print(num1,"/",num2,"=", divide(num1,num2))
else:
    print("无效输入")

这个计算器代码可以让用户选择操作，输入两个数字，然后根据用户选择的操作进行计算。

python写一个计算器代码

好的，以下是一个简单的计算器代码：

import tkinter as tk

# 创建主窗口
root = tk.Tk()
root.title('计算器')

# 显示结果的文本框
result = tk.Entry(root, width=30, font=('Arial', 14))
result.grid(row=0, column=0, columnspan=4, padx=10, pady=10)

# 数字按钮的点击事件
def button_click(number):
    current = result.get()
    result.delete(0, tk.END)
    result.insert(0, str(current) + str(number))

# 运算符按钮的点击事件

    current = result.get()
    global first_number
    global operation
    operation = operator
    first_number = int(current)
    result.delete(0, tk.END)

# 等于号按钮的点击事件
def button_equal():
    second_number = int(result.get())
    result.delete(0, tk.END)

    if operation == '+':
        result.insert(0, str(first_number + second_number))

        result.insert(0, str(first_number * second_number))
    elif operation == '/':
        result.insert(0, str(first_number / second_number))

# 清除按钮的点击事件
def button_clear():
    result.delete(0, tk.END)

# 创建数字按钮和运算符按钮

button_clear = tk.Button(root, text='C', padx=20, pady=10, command=button_clear)
button_equal = tk.Button(root, text='=', padx=20, pady=10, command=button_equal)

# 显示按钮
button_1.grid(row=1, column=0)
button_2.grid(row=1, column=1)
button_3.grid(row=1, column=2)
button_add.grid(row=1, column=3)

button_4.grid(row=2, column=0)
button_5.grid(row=2, column=1)
button_6.grid(row=2, column=2)
button_subtract.grid(row=2, column=3)

button_7.grid(row=3, column=0)
button_8.grid(row=3, column=1)
button_9.grid(row=3, column=2)

button_clear.grid(row=4, column=0)
button_0.grid(row=4, column=1)
button_equal.grid(row=4, column=2)

# 运行主循环
root.mainloop()

这是一个简单的计算器，你可以根据自己的需求进行修改和完善。
