    1、

    d={'001':89,"002":68,"003":87,"004":76,"005":71,"006":92}
    print(d["001"])
    print("007" in d)
    print(d.keys())
    print(d.values())
    print(d.items())
    print(d.pop("001"))
    print(d.get("005","查无此人"))
    del(d["003"])
    print(d)

     2、列表,元组,字典,集合的遍历。

    sa=set("3456")
    print(ss&sa)
    print(ss|sa)
    print(ss-sa)
    
    for i in ss:
        print(i,end='')
    print()
    
    lis=list("1234567")
    tu=tuple("dhrcnji")
    dt=dict(zip(lis,tu))
    
    for i in lis:
        print(i,end='')
    print()
    
    for i in tu:
        print(i,end='')
    print()
    
    for i in dt:
        print(i,dt[i])
