x=3.142

print(round(x,4), round(x))

a,b,c=3,4,5

a=b

b=c

print(a,b,c)的结果为：

aa=2

print(str(“aa”)*2)

s='AUDIT'

"{1:3}".format("audit",s)

ls[2][-1][1]

的运行结果是:

d ={"大海":"蓝色", "田野":"黄色", "大地":"黑色"}

print(d["大地"],d.get("宇宙", "黄色"))

ls=["audittt",[{4:5},6],[7,8]]

print(len(ls))

a = "AUDIT"

b = a[::-1]

print(b)
