Python 提供了getopt模块来获取命令行参数。 $ python test.py arg1 arg2 arg3 Python 中也可以使用sys的sys.argv来获取命令行参数: sys.argv 是命令行参数列表。 len(sys.argv) 是命令行参数个数。 注:sys.argv[0] 表示脚本名。 实例 test.py 文件代码如下: 实例 #!/usr/bin/python # -*- coding: ...

You can find the total number of command-line arguments using the sys.argv list in Python. We will pass the sys.argv list to thelen()function as an input argument. Thelen()function will return the length of the sys.argv list. As the first element of the sys.argv list is the name of...
Argparse in Python is a built-in module used to parse command-line arguments. Here’s a simple example of how to use it: importargparse parser=argparse.ArgumentParser()parser.add_argument('--name')args=parser.parse_args()print(args.name)# Output:# Whatever value you passed in with --name...
