The core difference between Go and Python in memory management is the different garbage collection mechanisms. Go uses concurrent mark clearance (MarkandSweep) GC, which automatically runs and executes concurrently with program logic, effectively deals with circular references. It is suitable for high concurrency scenarios, but cannot accurately control the recycling time; while Python mainly relies on reference counting, and object references are immediately released when zeroed. The advantage is that they are instant recycling and simple implementation, but there is a circular reference problem, so they need to use the GC module to assist in cleaning. In actual development, Go is more suitable for high-performance server programs, while Python is suitable for script classes or applications with low performance requirements.

An interface is not a pointer type, it contains two pointers: dynamic type and value. 1. The interface variable stores the type descriptor and data pointer of the specific type; 2. When assigning the pointer to the interface, it stores a copy of the pointer, and the interface itself is not a pointer type; 3. Whether the interface is nil requires the type and value to be judged at the same time; 4. When the method receiver is a pointer, only the pointer type can realize the interface; 5. In actual development, pay attention to the difference between the value copy and pointer transfer of the interface. Understanding these can avoid runtime errors and improve code security.

Golang and Python's standard libraries differ significantly in design philosophy, performance and concurrency support, developer experience, and web development capabilities. 1. In terms of design philosophy, Go emphasizes simplicity and consistency, providing a small but efficient package; while Python follows the concept of "bringing its own battery" and provides rich modules to enhance flexibility. 2. In terms of performance and concurrency, Go natively supports coroutines and channels, which are suitable for high concurrency scenarios; Python is limited by GIL, and multithreading cannot achieve true parallelism and needs to rely on heavier multi-process modules. 3. In terms of developer experience, Go toolchain forces code formatting and standardized import to improve team collaboration consistency; Python provides more freedom but can easily lead to style confusion. 4. Web development

IIS logs are stored in the inetpub\logs\LogFiles directory of the C drive by default and will not be cleaned automatically. The retention period needs to be controlled manually or through scripts. To modify the path, you can open IIS Manager → select a site or server node → double-click "Login" → click "..." to select a new directory. It is recommended to use non-system disks such as D:\IISLogs or multiple servers to configure the network path in a unified manner; set retention time can be achieved through LogParser scripts, task planning PowerShell scripts (such as 30 days of retention), third-party tools, etc.; in addition, it is recommended to adjust the log format as needed, close unnecessary fields, or temporarily close the debug log, and enable log compression to optimize performance and space usage.

Execute Shell commands in Go language can be implemented through the standard library os/exec. The basic method is to use exec.Command() to create a command object and call Output() to get the result; 1. Create a command object when executing a simple command and call Output() to get the output; 2. When real-time output is required, use StdoutPipe and StderrPipe to execute and print while executing; 3. For complex commands containing pipelines or redirects, they can be handed over to /bin/sh-c for analysis and processing; 4. In terms of security, avoid splicing user input, and it is recommended to pass a parameter list; 5. The control command background operation can be achieved by combining Start() and Wait();
