Python sys module stores the command line arguments into a list, we can access it usingsys.argv. This is very useful and simple way to read command line arguments as String. Let’s look at a simple example to read and print command line arguments using python sys module. import sys print...
You can get access to the command line parameters using the sys module. len(sys.argv) contains the number of arguments. To print all of the arguments simply execute str(sys.argv) #!/usr/bin/python importsys print('Arguments:', len(sys.argv)) print('List:', str(sys.argv)) Example: ...

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: ...
args = arguments.Args() print args.get(0) 1. 2. 3. Run python test.py 123 will print 123. 处理输入流 AI检测代码解析 from clint import piped_in if __name__ == '__main__': in_data = piped_in() print in_data 1. 2.
