How do I reset the values of input x and y?
问题
使用input()函数从控制台获取两个整数x和y作为输入。对于每个赋值运算符(=, +=, -=, 和 *=)，请将这些运算符应用于两个输入整数，并按示例显示结果。
假设:
- y 是一个非零整数
提示: 在每次赋值操作之前，将x和y的值重置为初始值。
这是我的代码行：
x = int(input("x: "))
y = int(input("y: "))
x_temp = x # 用于保存初始x的值
y_temp = y # 用于保存初始y的值
x = y
print("x = y:", x)
x = x_temp # 重置x为初始值
x += y
print("x += y:", x)
x = x_temp # 重置x为初始值
x -= y
print("x -= y:", x)
x = x_temp # 重置x为初始值
x *= y
print("x *= y:", x)
如何重置x和y的值到初始值？
示例输入和输出:
x: 20
y: 30
x = y: 30
x += y: 50
x -= y: -10
x *= y: 600
英文:
Take two integers x and y as inputs from the console using input() function. For each assignment operator (=, +=, -=, and *=), print to the console, the result of applying these operators on the two input integers as shown in the example.
Assumption:
- y is a non-zero integer
Hint: Before every assignment operation, reset the values of x and y to the initial values.
This is my code line:
x = int(input("x: "))
y = int(input("y: "))
x = y
print("x = y:", x)
x += y
print("x += y:", x)
x -= y
print("x -= y:", x)
x *= y
print("x *= y:", x)
How do I reset the values of x and y to the initial values??
Sample Input and Output:
x: 20
y: 30
x = y: 30
x += y: 50
x -= y: -10
x *= y: 600

这是因为变量'x'在过程中不断变化，您可以将输入的x保存到另一个变量中，然后不断重置为这个值。
base_x = int(input("x: "))
y = int(input("y: "))
x = y
print("x = y:", x)
x = base_x
x += y
print("x += y:", x)
x = base_x
x -= y
print("x -= y:", x)
x = base_x
x *= y
print("x *= y:", x)
英文:
This is because the variable 'x' is constantly changing during the process, you can save the input x to another variable, and then reset to this value continuously
base_x = int(input("x: "))
y = int(input("y: "))
x = y
print("x = y:", x)
x = base_x
x += y
print("x += y:", x)
x = base_x
x -= y
print("x -= y:", x)
x = base_x
x *= y
print("x *= y:", x)

在这种情况下，你没有修改y，因为你只是重新赋值x。
我认为重新初始化x的唯一方法是在每次操作之前，将x=y赋值。
学习如何调试可以帮助你了解代码执行过程中发生了什么，以及变量如何被修改。
英文:
In this case you are not modyfing y since you are only reassigning x.
I think the only way to reinitialize x is that every time, before every operation, you assign x=y.
Learning how to debug can help you understand what's happening during the execution of the code and how the variables are modified

如果我理解正确，我假设这些初始值是输入值。所以最好使用初始值的副本执行这些操作（+，-，* 和 /），如以下代码：
x_initial = int(input("x: "))
y_initial = int(input("y: "))
x = x_initial
y = y_initial
x = y
print("x = y:", x)
# 重置
x = x_initial
y = y_initial
x += y
print("x += y:", x)
# 重置
x = x_initial
y = y_initial
x -= y
print("x -= y:", x)
# 重置
x = x_initial
y = y_initial
x *= y
print("x *= y:", x)
英文:
If I understand you correctly, I assume those initial values are the input values. So it is better to perform these operations (+, -, * and /) with copy of the initial values like the following code:
x_initial = int(input("x: "))
y_initial = int(input("y: "))
x = x_initial
y = y_initial
x = y
print("x = y:", x)
# Reset
x = x_initial
y = y_initial
x += y
print("x += y:", x)
# Reset
x = x_initial
y = y_initial
x -= y
print("x -= y:", x)
# Reset
x = x_initial
y = y_initial
x *= y
print("x *= y:", x)

获取初始输入，解包，然后在每次操作之前将x和y分配给初始值以进行重置。
init = int(input("x: ")), int(input("y: "))
x, y = init
x = y
print("x = y:", x)
x, y = init
x += y
print("x += y:", x)
x, y = init
x -= y
print("x -= y:", x)
x, y = init
x *= y
print("x *= y:", x)
# x: 20
# y: 30
# x = y: 30
# x += y: 50
# x -= y: -10
# x *= y: 600
英文:
Get intial input, unpack, then assign x and y to initial value before each operation to reset.
init = int(input("x: ")), int(input("y: "))
x, y = init
x = y
print("x = y:", x)
x, y = init
x += y
print("x += y:", x)
x, y = init
x -= y
print("x -= y:", x)
x, y = init
x *= y
print("x *= y:", x)
# x: 20
# y: 30
# x = y: 30
# x += y: 50
# x -= y: -10
# x *= y: 600
