A few are retained because MySQL needs them and (currently) uses the YACC parser. Reserved words can be used as identifiers when they are caused.MySQL allows some of the keywords to be used as unrecognized identifiers, because many people have been using them before.

, every system and every mode is abstract, but it will consume and degrade like a specific item. Throughout history, these old ways of life and production cannot escape the fate of elimination. Innovation and Development of Science and Technology will always bring about real changes. This means that, in the face of crisis, people need a new development direction and motivation, rather than repairing and supplementing aging parts. As it takes too long to ride a horse across Eurasia, if you are al

If you call the read () method directly for large file objects, unpredictable memory usage may occur. A good way is to use a fixed-length buffer to constantly read the file content. That is, through yield.
When I read two multi-G txt files using Python, I simply used the readlines method, and the result collapse
