系统环境: OS X 10.8
Python: version 2.7.5, built from source, isolated by virtualenv.
问题描述: 通过"source bin/active"进入virtualenv环境后, 在Python Shell中敲击方向键, 会出现">>>^[[C^[[D"等字样. 但在非virtualenv环境的Python Shell(系统自带版本, 源码构建版本)中并不会出现这种现象. 我想知道为什么会出现这样的问题, 以及如何修复.
PS: 小白问题, 才疏学浅, google无果后上来求教.

====================================================
感谢@吴涛的回答, 我基本知道从哪里入手解决这个问题了, 但是我的情况可能更加复杂一点, 原因可能与codecs这个package有关, 问题是在使用这个库之后才出现的, 与 python - Arrow keys in Putty returning [[A^ [[D^ [[B^ instead of moving the cursor 的描述可能有关联.

How do you create multi-dimensional arrays using NumPy?Apr 29, 2025 am 12:27 AM

Create multi-dimensional arrays with NumPy can be achieved through the following steps: 1) Use the numpy.array() function to create an array, such as np.array([[1,2,3],[4,5,6]]) to create a 2D array; 2) Use np.zeros(), np.ones(), np.random.random() and other functions to create an array filled with specific values; 3) Understand the shape and size properties of the array to ensure that the length of the sub-array is consistent and avoid errors; 4) Use the np.reshape() function to change the shape of the array; 5) Pay attention to memory usage to ensure that the code is clear and efficient.

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
