编写一个 Python 程序，使用临时变量、按位运算符和算术运算符交换两个数字。
交换两个数字的 Python 程序
这个交换两个数字的 python 程序帮助用户输入两个数值。接下来，Python 使用临时变量交换这两个值。
a = float(input(" Please Enter the First Value a: "))
b = float(input(" Please Enter the Second Value b: "))
print("Before Swapping two Number: a = {0} and b = {1}".format(a, b))
temp = a
a = b
b = temp
print("After Swapping two Number: a = {0} and b = {1}".format(a, b))Python 交换两个数字输出
Please Enter the First Value a: 10
Please Enter the Second Value b: 20
Before Swapping two Number: a = 10.0 and b = 20.0
After Swapping two Number: a = 20.0 and b = 10.0在上面的 python 程序示例中，我们分配了 a = 10 和 b = 20
Temp = a–为 Temp 变量
赋值 Temp = 10
a = b–将 b 值赋给变量 a
a = 20
b =温度–变量 b 的温度值
b = 10
用函数交换两个数字的 Python 程序
这个换号的程序和上面一样，但是这次我们用函数分离逻辑。
def swap_numbers(a, b):
temp = a
a = b
b = temp
print("After: num1 = {0} and num2 = {1}".format(a, b))
num1 = float(input(" Please Enter the First Value : "))
num2 = float(input(" Please Enter the Second Value : "))
print("Before: num1 = {0} and num2 = {1}".format(num1, num2))
swap_numbers(num1, num2) Please Enter the First Value : 15
Please Enter the Second Value : 25
Before: num1 = 15.0 and num2 = 25.0
After: num1 = 25.0 and num2 = 15.0Python 使用算术运算符交换两个数字
在这个 Python 示例中，我们将使用算术运算符来代替使用 temp 或第三个变量来交换两个数字
a = float(input(" Please Enter the First Value a: "))
b = float(input(" Please Enter the Second Value b: "))
print("Before Swapping two Number: a = {0} and b = {1}".format(a, b))
a = a + b
b = a - b
a = a - b
print("After Swapping two Number: a = {0} and b = {1}".format(a, b))用户输入的值是 a = 25 和 b = 45
a = a+b = 25 + 45 = 70
b = a-b = 70 -45 = 25
a = a-b = 70–25 = 45
Python 使用按位运算符交换两个数字
这里，我们使用位运算符来交换两个数字。
a = int(input(" Please Enter the First Value : "))
b = int(input(" Please Enter the Second Value : "))
print("Before: a = {0} and b = {1}".format(a, b))
a = a^b
b = a^b
a = a^b
print("After: a = {0} and b = {1}".format(a, b))使用按位运算符输出
Please Enter the First Value : 111
Please Enter the Second Value : 222
Before: a = 111 and b = 222
After: a = 222 and b = 111原创文章，作者：小蓝，如若转载，请注明出处：https://www.506064.com/n/237651.html
