    1. pandas.DataFrame.to_sql to MySQL

    Until pandas include the option of INSERT IGNORE in the default pd.DataFrame.to_sql class, here is the best solution:

    from sqlalchemy.ext.compiler import compiles
    from sqlalchemy.sql.expression import Insert
    
    # adds the word IGNORE after INSERT in sqlalchemy
    @compiles(Insert)
    def _prefix_insert_with_ignore(insert, compiler, **kw):
        return compiler.visit_insert(insert.prefix_with('IGNORE'), **kw)

    Now you can run your normal df.to_sql commands!

    from sqlalchemy import create_engine
    from sqlalchemy.ext.compiler import compiles
    from sqlalchemy.sql.expression import Insert
    
    @compiles(Insert)
    def _prefix_insert_with_ignore(insert, compiler, **kw):
        return compiler.visit_insert(insert.prefix_with('IGNORE'), **kw)
    
    df.index.rename('index_column', inplace=True)
    sqlEngine = create_engine('mysql+pymysql://'+dbUser+':'+dbPass+'@'+dbHost+'/'+dbDbse, pool_recycle=3600)
    dbConnection = sqlEngine.connect()
    try: df.to_sql(dbTble, con=dbConnection, if_exists='append')
    except ValueError as vx: print(vx)
    except Exception as ex: print(ex)
    else: print("Table %s created successfully."%dbTble)
    

    2. SQL Server

    If you really need to run multiple threads at the same time you can enable the ignore_dup_key option on the primary key.

    This will just give a warning instead of an error when an insert would result in a duplicate key violation. But instead of failing it will discard the row(s) that if inserted would cause the uniqueness violation.

    CREATE TABLE [dbo].[DeleteMe](
    [id] [uniqueidentifier] NOT NULL,
    [Value] [varchar](max) NULL,
    CONSTRAINT [PK_DeleteMe] 
    PRIMARY KEY ([id] ASC) 
    WITH (IGNORE_DUP_KEY = ON));
    

    Example on sqlfiddle

    Paul White's detailed explanation on the IGNORE_DUP_KEY option. Thanks Paul.

    关于EOF occurred in violation of protocol (_ssl.c:661)的解决办法

    直接上代码(python版本2.7)
    `import requests
    r = requests.get('https://www.zjkill.com/news/')
    r.encoding = 'utf8'
    print r.text
    print r.status_code,r.url`
    报错

    requests.exceptions.SSLError: ("bad handshake: SysCallError(-1, 'Unexpected EOF')",)
    经过一番查找,发现是requests不在支持3DES stream cipher。
    下面是解决办法,注意ruquests版本2.11及以下的
    from requests.adapters import HTTPAdapter
    from requests.packages.urllib3.poolmanager import PoolManager
    import ssl
    
    class MyAdapter(HTTPAdapter):
        def init_poolmanager(self, connections, maxsize, block=False):
            self.poolmanager = PoolManager(num_pools=connections,
                                           maxsize=maxsize,
                                           block=block,
                                           ssl_version=ssl.PROTOCOL_TLSv1)
    s = requests.Session()
    s.mount('https://', MyAdapter())
    r = requests.get('https://www.zjkill.com/news/')
    r.encoding = 'utf8'
    print r.text

    如果requests版本是2.12及以上

    import requests
                    from requests.adapters import HTTPAdapter
                    from requests.packages.urllib3.util.ssl_ import create_urllib3_context
                    CIPHERS = (
                        'ECDH+AESGCM:DH+AESGCM:ECDH+AES256:DH+AES256:ECDH+AES128:DH+AES:ECDH+HIGH:'
                        'DH+HIGH:ECDH+3DES:DH+3DES:RSA+AESGCM:RSA+AES:RSA+HIGH:RSA+3DES:!aNULL:'
                        '!eNULL:!MD5'
                    )
    
                    class DESAdapter(HTTPAdapter):
                        """
                        A TransportAdapter that re-enables 3DES support in Requests.
                        """
    
                        def init_poolmanager(self, *args, **kwargs):
                            context = create_urllib3_context(ciphers=CIPHERS)
                            kwargs['ssl_context'] = context
                            return super(DESAdapter, self).init_poolmanager(*args, **kwargs)
    
                        def proxy_manager_for(self, *args, **kwargs):
                            context = create_urllib3_context(ciphers=CIPHERS)
                            kwargs['ssl_context'] = context
                            return super(DESAdapter, self).proxy_manager_for(*args, **kwargs)
    
                    s = requests.Session()
                    s.mount('https://www.zjkill.com/', DESAdapter())
                    r = s.get(url)
                    r.encoding = 'utf8'
                    print r.text

    因为我用的python2.7,python3的解决办法就不写,那个更简单,可以自行网上搜索。

    显然pip是使用国内的python镜像源,没有被墙。
    仔细检测发现,是打开的VPN软件忘记了关闭,关闭以后恢复正常。
