import binascii

　　

    geovin=b"geovindu"
    adu=base64.b64encode(geovin) #加密码
    print(adu)
    edu=base64.b64decode(adu) #解密
    print(edu)

　　

    s=["医疗",400,1]
    column=('InsuranceName','InsuranceCost','IMonth')
    tbname="InsuranceMoney"
    vls = str(s).replace("[", "").replace("]", "")
    cls = str(column).replace("'", "").replace("'", "")
    sqlstring = f"insert into {tbname} {cls} values ({vls})"
    print(sqlstring)

　　

 

            pwd=str(base64.b64decode(ds["password"]),encoding='utf-8')
            print(pwd)

    print(str(b'123', encoding='utf-8'))
    print(bytes.decode(b'123'))
