为什么argv有一个'v' [英] Why does argv have a 'v'

问题描述

我正在以新手程序员的身份学习Python.我已经看到了argv，就像在sys.argv中一样，我相信它也在其他语言中也使用过. "argv"中"v"的含义是什么?它代表什么意思，该术语起源于何处?

I am studying Python as a novice programmer. I have seen argv, as in sys.argv used and I believe it is used in other languages as well. What is the significance of the 'v' in 'argv'? What does it stand for and where does the term originate?

我希望这可以帮助我理解和记住"argv"的使用.

I am hoping this will help me understand and remember the use of "argv".

推荐答案

变量分别命名为argc( argument count )和argv( argument vector em> )，按照惯例，来自C.

The variables are named argc (argument count) and argv (argument vector) by convention, from C.

请注意，在Python中没有sys.argc.您只需按照 fred-larson的指示使用len(sys.argv)

note that in Python there's no sys.argc. You just use len(sys.argv) as pointed fred-larson
