CentOS python environment configuration
@(Study notes)
Use pyenv to manage python version
- ##pyenv tool configuration:
$ git clone https://github.com/yyuu/pyenv.git ~/.pyenv $ echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.bash_profile $ echo 'export PATH="$PYENV_ROOT/bin:$PATH"' >> ~/.bash_profile $ echo 'eval "$(pyenv init -)"' >> ~/.bash_profile $ exec $SHELL
- Common pyenv commands:
$ pyenv install 2.7.6 // 安装python 2.7.6版本 $ pyenv local 2.7.6 // 这个应用使用2.7.6版本 $ pyenv global 2.7.6 // 全局环境版本 $ pyenv versions // 列出已经安装的所有版本,*表示当前环境正在使用的版本 2.5.6 2.6.8 *2.7.6 (set by /home/yyuu/.pyenv/version) 3.3.3 jython-2.5.3 pypy-2.2.1
- pip installation:
# 首先安装epel扩展源: $ sudo yum -y install epel-release # 然后安装python-pip $ sudo yum -y install python-pip # 清理cache $ sudo yum clean all
- Pip common commands:
# 安装1.9版本的django pip install django==1.9 # 卸载包 $ pip uninstall <包名> 或 pip uninstall -r requirements.txt # 更新包 $ pip install -U <包名> # 更新pip $ pip install -U pip # 显示包所在的目录 $ pip show -f <包名> # 搜索包 $ pip search <搜索关键字> # 查询可升级的包 $ pip list -o # 国内pypi镜像 # 豆瓣:https://pypi.douban.com/simple # 中国科学技术大学:https://mirrors.tuna.tsinghua.edu.cn/pypi/web/simple/ # 清华大学TUNA:https://pypi.tuna.tsinghua.edu.cn/simple
The above is the detailed content of CentOS python environment configuration method. For more information, please follow other related articles on the PHP Chinese website!

Python is easier to learn and use, while C is more powerful but complex. 1. Python syntax is concise and suitable for beginners. Dynamic typing and automatic memory management make it easy to use, but may cause runtime errors. 2.C provides low-level control and advanced features, suitable for high-performance applications, but has a high learning threshold and requires manual memory and type safety management.

Python and C have significant differences in memory management and control. 1. Python uses automatic memory management, based on reference counting and garbage collection, simplifying the work of programmers. 2.C requires manual management of memory, providing more control but increasing complexity and error risk. Which language to choose should be based on project requirements and team technology stack.

Python's applications in scientific computing include data analysis, machine learning, numerical simulation and visualization. 1.Numpy provides efficient multi-dimensional arrays and mathematical functions. 2. SciPy extends Numpy functionality and provides optimization and linear algebra tools. 3. Pandas is used for data processing and analysis. 4.Matplotlib is used to generate various graphs and visual results.

Whether to choose Python or C depends on project requirements: 1) Python is suitable for rapid development, data science, and scripting because of its concise syntax and rich libraries; 2) C is suitable for scenarios that require high performance and underlying control, such as system programming and game development, because of its compilation and manual memory management.

Python is widely used in data science and machine learning, mainly relying on its simplicity and a powerful library ecosystem. 1) Pandas is used for data processing and analysis, 2) Numpy provides efficient numerical calculations, and 3) Scikit-learn is used for machine learning model construction and optimization, these libraries make Python an ideal tool for data science and machine learning.

Is it enough to learn Python for two hours a day? It depends on your goals and learning methods. 1) Develop a clear learning plan, 2) Select appropriate learning resources and methods, 3) Practice and review and consolidate hands-on practice and review and consolidate, and you can gradually master the basic knowledge and advanced functions of Python during this period.

Key applications of Python in web development include the use of Django and Flask frameworks, API development, data analysis and visualization, machine learning and AI, and performance optimization. 1. Django and Flask framework: Django is suitable for rapid development of complex applications, and Flask is suitable for small or highly customized projects. 2. API development: Use Flask or DjangoRESTFramework to build RESTfulAPI. 3. Data analysis and visualization: Use Python to process data and display it through the web interface. 4. Machine Learning and AI: Python is used to build intelligent web applications. 5. Performance optimization: optimized through asynchronous programming, caching and code

Python is better than C in development efficiency, but C is higher in execution performance. 1. Python's concise syntax and rich libraries improve development efficiency. 2.C's compilation-type characteristics and hardware control improve execution performance. When making a choice, you need to weigh the development speed and execution efficiency based on project needs.
