字典 dict
    键 ：值 对

　　 布尔值  True == 1   False == 0 不建议作为键  会冲突覆盖

zidian1 = {
    "k1" : "v1",
    "k2" : "v2",
    "k3" : "v3",
    "k4" : "v4",
    "k5" : "v5",
    "k6" : "v6",
    "test" : "test"
}

del  zidian1["test"]
print(zidian1)
print(zidian1["k1"])
zidian1_len = len(zidian1)
print(zidian1_len)

    print(item,"：",zidian1[item],"\\t",end="")
