Go language method to determine whether it is a file or a folder:
// 判断所给路径文件/文件夹是否存在 func Exists(path string) bool { _, err := os.Stat(path) //os.Stat获取文件信息 if err != nil { if os.IsExist(err) { return true } return false } return true } // 判断所给路径是否为文件夹 func IsDir(path string) bool { s, err := os.Stat(path) if err != nil { return false } return s.IsDir() } // 判断所给路径是否为文件 func IsFile(path string) bool { return !IsDir(path) }
isdir:
Function: Determine input (string) Whether to represent a folder. This function can also be used to determine whether a folder exists.
Syntax format:
tf = isdir('A')
If A is a folder, return logical 1 (true), otherwise return 0 (false).

C is more suitable for scenarios where direct control of hardware resources and high performance optimization is required, while Golang is more suitable for scenarios where rapid development and high concurrency processing are required. 1.C's advantage lies in its close to hardware characteristics and high optimization capabilities, which are suitable for high-performance needs such as game development. 2.Golang's advantage lies in its concise syntax and natural concurrency support, which is suitable for high concurrency service development.

Golang excels in practical applications and is known for its simplicity, efficiency and concurrency. 1) Concurrent programming is implemented through Goroutines and Channels, 2) Flexible code is written using interfaces and polymorphisms, 3) Simplify network programming with net/http packages, 4) Build efficient concurrent crawlers, 5) Debugging and optimizing through tools and best practices.

The core features of Go include garbage collection, static linking and concurrency support. 1. The concurrency model of Go language realizes efficient concurrent programming through goroutine and channel. 2. Interfaces and polymorphisms are implemented through interface methods, so that different types can be processed in a unified manner. 3. The basic usage demonstrates the efficiency of function definition and call. 4. In advanced usage, slices provide powerful functions of dynamic resizing. 5. Common errors such as race conditions can be detected and resolved through getest-race. 6. Performance optimization Reuse objects through sync.Pool to reduce garbage collection pressure.

Go language performs well in building efficient and scalable systems. Its advantages include: 1. High performance: compiled into machine code, fast running speed; 2. Concurrent programming: simplify multitasking through goroutines and channels; 3. Simplicity: concise syntax, reducing learning and maintenance costs; 4. Cross-platform: supports cross-platform compilation, easy deployment.
