Аргументы командой строки
При запуске программ через терминал можно указывать аргументы через пробел. В Python список этих аргументов хранится в переменной argv во встроенном модуле sys.
Первым элементом всегда является имя запускаемого скрипта, вторым и далее — непосредственно сами аргументы.

The lead from Wall Street offers little clarity as the major averages opened lower on Friday and then bounced back and forth across the unchanged line, finally finishing mixed and little changed.The Dow added 33.18 points or 0.10 percent to finish at 34,798.00, while the NASDAQ eased 4.54 points or 0.03 percent to close at 15,047.70 and the S&P 500 rose 6.50 points or 0.15 percent to end at 4,455.48. For the week, the Dow rose 0.6 percent, the NASDAQ added 0.1 percent and the S&P gained 0.5 percent.The lackluster performance on Wall Street came on uncertainty about the outlook for the markets following recent volatility.
