sys.argv用于取得执行python程序时的参数

通过一个示例说明

➜ sys_argv tree.

├── init.py

├── argv_01.py

├── argv_02.py

# argv_01.py
import sys

from sys_argv.argv_02 import argv_02_func_01

print ('this is argv_01')
print(sys.argv)
argv_02_func_01()

# argv_02.py
import sys
def argv_02_func_01():
    print('this is argv02')
    print('this is argv02')
    print('this is argv02')
    print(sys.argv)
    print('this is argv02')
    print('this is argv02')

运行argv_01后的输出结果为：

this is argv_01

['/Users/mac/Django/python高级语法/sys_argv/argv_01.py']

this is argv02

this is argv02

this is argv02

['/Users/mac/Django/python高级语法/sys_argv/argv_01.py']

this is argv02

this is argv02

可见：

在文件2中打印sys.argv，也是打印文件1的文件名。
