I've been hearing the buzz about virtualenv lately, and I'm interested. But all I've heard is a smattering of praise, and don't have a clear understanding of what it is or how to use it. I'm looking for (ideally) a follow-along tutorial that can take me from Windows or Linux with no Python on it, and explain every step of (in no particular order): what I should do to be a
最近我一直听到关于virtualenv的嗡嗡声，而且我很感兴趣。 但我所听到的只是一丝赞美，对于它是什么以及如何使用它没有清晰的认识。 我正在寻找（理想情况下）一个后续的教程，可以让我从Windows或Linux中获得没有Python的内容，并且解释每一步（没有特定的顺序）： 我应该怎么做才能开始使用virtualenv 为什么使用virtualenv是一个好主意的具体原因 我可以/不能使用virtualenv 我应该/不应该使用virtualenv 并且（
I'm just learning python and confused when a "def" of a function ends? I see code samples like: def myfunc(a=4,b=6): sum = a + b return sum myfunc() I know it doesn't end because of the return (because I've seen if statements... if FOO than return BAR, else return FOOBAR). How does Python know this isn't a recursive function that calls itself? When the fun
我只是在学习python，并且在函数的“def”结束时感到困惑？ 我看到如下代码示例： def myfunc(a=4,b=6): sum = a + b return sum myfunc() 我知道它并没有因为返回而结束（因为我已经看到了如果语句...如果FOO比返回BAR，否则返回FOOBAR）。 Python如何知道这不是一个自我调用的递归函数？ 当函数运行时，它会继续执行程序，直到它找到返回值？ 那会导致一些有趣的错误。 谢谢 在Python中，空白是很重要的。
While I like to think of myself as a reasonably competent Python coder, one aspect of the language I've never been able to grok is decorators. I know what they are (superficially), I've read tutorials, examples, questions on Stack Overflow, and I understand the syntax, can write my own, occasionally use @classmethod and @staticmethod, but it never occurs to me to use a decorator to solv
虽然我喜欢把自己看作是一个合理的Python编码器，但我从来没有能够理解的语言的一个方面是装饰器。 我知道他们是什么（表面上），我已经阅读了关于Stack Overflow的教程，示例，问题，并且我理解语法，可以编写自己的，偶尔使用@classmethod和@staticmethod，但是我从来没有想过使用装饰者来解决我自己的Python代码中的问题。 我从来没遇到过这样的问题：“呃......这看起来像是一个装饰工的工作！” 所以，我想知道你们是否
Hey guys, I'm having issues calling functions from argpars. This is a simplified version of my script and this works, printing whatever value I give -s or -p import argparse def main(): parser = argparse.ArgumentParser(description="Do you wish to scan for live hosts or conduct a port scan?") parser.add_argument("-s", dest='ip3octets', action='store', help='Enter the first three o

hi guys just needing so help with reading .txt into a list I think what I've got so far is r = open('RegsInList.txt','r') rr =(r.readlines()) #print(rr) this works it imports the text file and reads it I need it to read into a list. So I can put it under list obj and then it to split it up listobj = ['AV46 WAD','WD40 ASD','BG65 KYS','WA48 DFT','GH09 DEG'] var1, var2, var3,var4 ,var5 = li
