argparse模块默认检查命令行参数sys.argv,也可直接解析字符串。例如,args = parser.parse_args('foo 1 -x 2'.split()),这在调试中很有用。 注意,argparse模块为Python2.7版本新增。在以前的版本中,可使用getopt模块解析命令行。如下所示: AI检测代码解析 def Usage(): ''' usage: CLineCounter.py [options]...
Thegetoptmodule is a parser for command line options whose API is designed to be familiar to users of the Cgetopt()function. Users who are unfamiliar with the Cgetopt()function or who would like to write less code and get better help and error messages should consider using theargparsemodule...
Argument Validation: argparse provides built-invalidationfor arguments, so you can enforce rules on the values provided by the user. Here's a simple example of how to use argparse in a Python script: import argparse # Create an ArgumentParser objectparser= argparse.ArgumentParser(description='A sim...
Each option-and-value pair returned has the option as its first element, prefixed with a hyphen for short options (e.g.,‘-x’) or two hyphens for long options (e.g.,‘--long-option’), and the option argument as its second element, or an empty string if the option has no ...

To use Docker Compose, you had to call the docker-compose (with a hyphen) executable in the command line. However, it’s now integrated into the Docker platform, so you can invoke Docker Compose as the docker compose plugin. Both commands should work the same, as the plugin is meant to...

本⽂对于先前系列⽂章中实现的C/Python代码统计⼯具(CPLineCounter),通过C扩展接⼝重写核⼼算法加以优化,并与⽹上常见的统计⼯具做对⽐。实测表明,CPLineCounter在统计精度和性能⽅⾯均优于其他同类统计⼯具。以千万⾏代码为例评测性能,CPLineCounter在Cpython和Pypy环境下运⾏时,⽐国外...
), PyPI will ignore your expressed intention and “normalize” the name so that each such delimiter (or even runs of delimiters) is replaced with a single hyphen. So, to avoid confusion, I suggest that, when the project name has two or more words joined by delimiters, you specify hyphens...
