Why does IronPython tell me that pip is a package and not an executable?

阅读更多关于 Why does IronPython tell me that pip is a package and not an executable?

问题 I am a complete newbie at Python. I wanted to try to see if Pyomo (a Python package for mathematical modeling) could work under IronPython because all my code for generating the data needed for Pyomo is in C#. I installed IronPython 2.7.5, then tried as an administrator the advice found in http://blog.ironpython.net/2014/12/pip-in-ironpython-275.html#disqus_thread on how to run "pip" for IronPython. I used the exact example they gave (installing html5lib ): ipy -X:Frames -m ensure pip ipy -X

引言 python是什么？ python是编程语言，即python是语言语言有英语、法语、葡萄牙语等，但凡是语言，都是用来沟通的介质。程序员编程的本质就是让计算机去工作，而编程语言就是程序员与计算机沟通的介质什么是编程？编程，是个动词，“编程”就等于“写代码”。写代码的目的就是为了让计算机做我们想要让它做的事情。所以如果我们现在想要让一台电脑听你的话去干活，就得使用它能够理解的语言去让它干活。计算机只能理解“二进制”，也就是只能使用“0”和“1”来与计算机进行交流。例如，010110100100010011。 Python编程语言的排名（TIOBE链接： https://www.tiobe.com/tiobe-index/ ） python介绍 python的创始人为吉多·范罗苏姆（Guido van Rossum）。1989年的圣诞节期间，吉多·范罗苏姆（中文名字：龟叔）为了在阿姆斯特丹打发时间，决心开发一个新的脚本解释程序，作为ABC语言的一种继承。（龟叔：2005年加入谷歌至2012年，2013年加入Dropbox直到现在，依然掌握着Python发展的核心方向，被称为仁慈的独裁者）。 2017年7月的TIOBE排行榜，Python已经占据第四的位置， Python崇尚优美、清晰、简单，是一个优秀并广泛使用的语言。由上图可见，Python整体呈上升趋势

Accessing the name of a list by defining a new class, error: NamedList instance has no attribute 'len'

问题 I am pretty new to python, So I have created a list of elements like: main_list = [1,2,3] I want this list to have a name and I don't want to use a dictionary, so I have created a class with the name as an attribute: class NamedList: def __init__(self, name, obj) self.name = name self.object = obj when I try to access the length of the first list: len(main_list) #works fine but for the second one it gives me this error: NamedList instance has no attribute ' len ' : new_main_list = NamedList(

IronPython support for Visual Studio debugging like Set Next Statement and Edit-and-Continue

问题 I'm evaluating IronPython for a project. I'm trying to get it working with typical Windows Visual Studio .NET debugging features: Set Next Statement (move the instruction pointer to another line of code) Edit and Continue (this lets you edit lines of code live. It's useful for eliminating bugs.) The most basic debug functions seem to work out of the box. (Setting breakpoints, watches, etc.) However, I've struggled to get these 2 features working. Are they supported by IronPython? I tried

Is it possible to check the syntax of a python script before running it when making use of IronPython and C#?

问题 Since I solved the issue of checking the syntax, I shall elaborate on how I did this. I will use my own implementation as an example. First of all what have I used and how I have used it? I made use of the ast module available in IronPython since version 2.6 (I made use of 2.7.4(1)). The ast module builds an abstract syntax tree(2) (ast for short) of code supplemented to the module. This function made it possible for me to know if a script had a good syntax or not. As such I knew if the

问题 Disclaimer - I'm not familiar with Python. I'm a C# developer who has written an application to execute Python scripts (authored by others) using IronPython. These scripts have so far have only needed to use import math , but one of our users has asked for the application to support for Numpy. I have installed Numpy on my PC (using the 'numpy-1.9.2-win32-superpack-python2.7.exe' file), which has created a numpy folder under \Lib\site-packages. I've written a two-line Python script to test
