How to find the python installation path?

When using python, sometimes you need to find the installation location of the python package and find other installed third-party packages. Let's take a look at how to find the installation path of python on the Linux platform.

View on Linux platform

For the Linux platform, many running system software are based on python. If python goes wrong, then The entire system may be at risk of major problems.

We take CentOS 7 as an example. In CentOS7, the basic version of python is 2.7, as shown in the figure below.

How to find the python installation path

After the python command can be executed correctly, we first find the location of the python command. The command to find python is:

whereis python

The results are as follows, you can see The path is /usr/bin/python

## Then we can use this command to find out which installation package it has. The command is:

rpm - qf /usr/bin/python

The result is as shown in the picture below. You can see that the installation package is python-2.7.5

Then we You can find the installation paths of all files in the python installation package. The command to query the path of all files in the installation package is:

rpm -ql python-2.7.5

as shown below As shown in, you can see that all python command paths are displayed.

But the above results do not show the location of all python library files, and you still need to find them. In Linux, the package name of the library file is generally the program name - libs. If we want to search for python here, the corresponding package name is python-libs. We use the rpm -qa command to query the following, and we can see that this package does exist. As shown in the figure below:

After finding this package, execute the same query command

rpm -ql python-libs

The corresponding results will all come out, as shown in the second picture below:

If you install a lot of third-party library files, then the query results will be very long. Press the space bar to turn the page and scroll all the way to the bottom to see the location of the python-libs help file, as shown in the picture below. At this point, the installation paths of all python files on Linux have been found

Python vs. C : Learning Curves and Ease of UseApr 19, 2025 am 12:20 AM

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 vs. C : Memory Management and ControlApr 19, 2025 am 12:17 AM

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 for Scientific Computing: A Detailed LookApr 19, 2025 am 12:15 AM

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.

Python and C : Finding the Right ToolApr 19, 2025 am 12:04 AM

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 for Data Science and Machine LearningApr 19, 2025 am 12:02 AM

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.

Learning Python: Is 2 Hours of Daily Study Sufficient?Apr 18, 2025 am 12:22 AM

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.

Python for Web Development: Key ApplicationsApr 18, 2025 am 12:20 AM

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 vs. C : Exploring Performance and EfficiencyApr 18, 2025 am 12:20 AM

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.
