python-2.7

问题 I was playing with the dateutil module in Python 2.7.3. I simply wanted to use: import dateutil dateutil.parser.parse("01-02-2013") But I got an error: AttributeError: 'module' object has no attribute 'parser' I checked what attributes dateutil does have: print dir(dateutil) # output: ['__author__', '__builtins__', '__doc__', '__file__', '__license__', # '__name__', '__package__', '__path__', '__version__'] The thing is, when I try to import parser from dateutil directly, it does seem to

问题 How to use python 2 packages in python 3 project? I have a Python 3 project, but I need some packages which are written in Python 2. I do not want to rewrite these python-2 packages, so forking / 2to3 is not an option. 回答1: You can't. Any module you import in py3 codebase needs to be py3 compatible. If you can't make the upstream project do it for you, you'll have to do it yourself. As mentioned in the comments, 2to3 utility should help you with that. 回答2: A lot of the previous questions

问题 I want to make a pie chart animation in python where it will be changing continuously according to the data (which is being changed continuously through loop). The problem is that it is printing every pie chart one by one and I end up having many pie charts. I want one pie chart to change in place so that it seems like an animation. Any idea how to do this? I am using the following the code colors = ['gold', 'yellowgreen', 'lightcoral', 'lightskyblue', 'black', 'red', 'navy', 'blue', 'magenta

问题 I wanted to parse a fairly huge xml-like file which doesn't have any root element. The format of the file is: <tag1> <tag2> </tag2> </tag1> <tag1> <tag3/> </tag1> I tried using Element-Tree but it returned a "no root" error. Is there any other python library which can be used for parsing this file? Thanks in advance! :) PS: I tried adding an extra tag to wrap the entire file and then parse it using Element-Tree. However, I would like to use some more efficient method, in which I would not

问题 I wish to uninstall Python 2.7 and all packages connected to it. I initially installed Python from the official website and I installed all packages using the pip install command. Would uninstalling Python from the control panel also uninstall all packages automatically? The reason I want to uninstall Python is because I want to use Anaconda in order to be able to manage packages more easily and also be able to install both Python 2 and 3 to switch between them back and forth. 回答1: If you
