关于sys.argv []的Noob问题 [英] Noob question regarding sys.argv[]

问题描述

我是Python的新手，从未编写过C程序，但我用C ++编写。我从未使用过argv，但是一项任务要求我学习它并立即使用它。我正在使用Python 2.5，IDLE（用于编写代码），使用Win XP专业版环境（无法让我的Ubuntu看到我的无线网卡）。


我应该编写一个模块，它将从命令行中获取一个参数，该参数将读取文件并对其进行处理。我真的不知道该怎么做，并会欣赏勺子喂养版教程。


帮助，请？

我完全没事了Python的新手，从来没有写过C程序，但我用C ++编写。我从未使用过argv，但是一项任务要求我学习它并立即使用它。我正在使用Python 2.5，IDLE（用于编写代码），使用Win XP专业版环境（无法让我的Ubuntu看到我的无线网卡）。

帮助，好吗？

< blockquote>好的，所以说我的文件名是file.txt（它的格式是不一样的，比如.py？）。那是我的arg，对吗？所以：


python myModule.py file.txt


应该调用模块调用文本文件，对吧？


我感谢您的耐心等待。我一直在努力解决这个问题，我知道它应该是显而易见的，但由于某种原因它不是。

I''m completely new to Python, never wrote a C program, but I have written in C++. I''ve never used argv, but an assignment is requiring me to learn it and use it now. I''m using Python 2.5, IDLE (for writing code), using Win XP pro environment (can''t get my Ubuntu to see my wireless card).

I''m supposed to write a module that will take an argument from the command line that will read a file and process it. I really don''t know how to do this and would appreciate a spoon fed version tutorial.

Help, Please?

in a file (say myModule.py)

ok, so say my file name is file.txt (should it be formatted differently, like .py?). That is my arg, right? so:

python myModule.py file.txt

should call the module to call the text file, right?

I appreciate your patience. I''ve been trying to work this out all day, and I know it should be obvious, but for some reason it isn''t.
