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: ...
script_name= sys.argv[0]#第一个参数指的是脚本名称param_first = sys.argv[1]#第二个参数,此时也是一个str列表param_second = sys.argv[2]#第三个参数print(script_name)print(type(script_name))print(param_first)print(type(param_first)) ...
