python解析命令行参数主要有三种方法:sys.argv、argparse解析、getopt解析 方法一:sys.argv —— 命令行执行:python test_命令行传参.py 1,2,3 1000 # test_命令行传参.py import sys def para_input(): p
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: UTF-8 -*- importsys print'参数个数为:',len(sys.argv),'个参数。' ...

len(sys.argv)是命令行参数的数量。 这里sys.argv [0]是程序名称,即脚本的名称。比如在上面示例代码中,sys.argv [0]的值就是test.py。 示例 看看以下脚本command_line_arguments.py的代码 - #!/usr/bin/python3importsysprint('Number of arguments:',len(sys.argv...
