博客随笔皆为学习笔记，有诸多不足，如有错误，请帮我指出，不胜感激，我后续会补全校正

一、链式赋值

a = 10
b = 10
c = 10
d = 10
print(f'a:{a}, b:{b}, c:{c}, d:{d}')

a = b = c = d = 10
print(f'a:{a}, b:{b}, c:{c}, d:{d}')

二、交叉赋值

x = 100
y = 200

temp = x
x = y
y = temp
print(f'x:{x}')
print(f'y:{y}')

x, y = y, x
print(f'x:{x}')
print(f'y:{y}')
