1. 花式赋值
1.1 链式赋值
a = 10
b = 10
c = 10
print(a, b, c)
结果为:
10 10 10
链式赋值:
a = b = c = 10
print(a, b, c)
结果为:
10 10 10
1.2 交叉赋值
x = 123
y = 456
temp = x
x = y
y = temp
print(x, y)
结果为:
456 123
交叉赋值:
x = 123
y = 456
x, y = y, x
print(x, y)
结果为:
456 123
1.3 交叉赋值(解压缩)
height_of_nick, weight_of_nick, age_of_nick = 149, 180, 12
print(height_of_nick, weight_of_nick, age_of_nick)
结果为:
149 180 12
2. 注释
2.1 单行注释
# a = 2 # 注释此行,不执行
b = 3
print(b) # 打印b
单行注释一般注释在一行的后面,如果是语句块,则注释于语句块前
ctrl + / 注释多行,再次输入则取消注释
2.2 多行注释
