Course Introduction：The core difference between list and tuple is variability: 1.list is mutable, supporting modification, addition and removal of elements; 2.tuple is immutable, and content cannot be changed after creation. For example, modifying the list element or using the append() method is legal, and doing the same operation on the tuple will throw an error. Syntactically, list uses brackets[], and tuple uses brackets() or comma-separated definitions. In terms of performance, tuple is faster, suitable for large-scale reading operations and fixed data scenarios such as coordinate points. In addition, tuple can be used as a key to a dictionary, while list cannot. Therefore, when data is frequently changed, use list and tuple when data is ensured.

Course Introduction：Go is a new language, a concurrent, garbage-collected, fast-compiled language. It can compile a large Go program in a few seconds on a single computer. Go provides a model for software construction that makes dependency analysis easier and avoids most C-style include files and library headers. Go is a statically typed language, and its type system has no hierarchy. Therefore users do not need to spend time defining relationships between types, which feels more lightweight than typical object-oriented languages. Go is a completely garbage-collected language and provides basic support for concurrent execution and communication. By its design, Go is intended to provide a method for constructing system software on multi-core machines.
