Examples of file name and file path operations in python
The following editor will bring you an example of python file name and file path operation. The editor thinks it’s pretty good, so I’ll share it with you now and give it as a reference. Let’s follow the editor and take a look.
Readme:
In daily work, we often involve operations related to file names and file paths. In python, os The standard module provides us with various functions for file operations. This article will introduce respectively "get the current path", "get all files and folders under the current path", "delete files", "delete directories/multiple directories", "check File/File Path", "Check if file path exists", "Separate file path and file name", "Separate file extension", "Get file name" and Get "file path".
import os '''获得当前路径 ''' cwd=os.getcwd() print(cwd)
''' 得到当前文件夹下的所有文件和文件夹 ''' print(os.listdir())
''' delete file ''' os.remove('sw724.vaps') print(os.listdir())
''' 删除单个目录和多个目录 ''' os.removedir() os.removedir()
''' 检查是否是文件/文件夹 ''' print(os.path.isfile('/Users/liuxiaolong/PycharmProjects/untitled/sw724.vaps')) print(os.path.isdir('/Users/liuxiaolong/PycharmProjects/untitled/sw724.vaps'))
''' 检查文件路径是否存在 ''' print(os.path.exists('/Users/liuxiaolong/PycharmProjects/untitled/iiii'))
''' 分离文件名 分离扩展名 ''' [dirname,filename]=os.path.split('/Users/liuxiaolong/PycharmProjects/untitled/sw724.vaps') print(dirname,"\n",filename) [fname,fename]=os.path.splitext('/Users/liuxiaolong/PycharmProjects/untitled/sw724.vaps') print(fname,"\n",fename)
''' 获得文件路径 获得文件名 获得当前环境 ''' print("get pathname:",os.path.dirname('/Users/liuxiaolong/PycharmProjects/untitled/sw724.vaps')) print("get filename:",os.path.basename('/Users/liuxiaolong/PycharmProjects/untitled/sw724.vaps')) print(os.getenv)

PHP and Python have their own advantages and disadvantages, and the choice depends on project needs and personal preferences. 1.PHP is suitable for rapid development and maintenance of large-scale web applications. 2. Python dominates the field of data science and machine learning.

Efficient training of PyTorch models on CentOS systems requires steps, and this article will provide detailed guides. 1. Environment preparation: Python and dependency installation: CentOS system usually preinstalls Python, but the version may be older. It is recommended to use yum or dnf to install Python 3 and upgrade pip: sudoyumupdatepython3 (or sudodnfupdatepython3), pip3install--upgradepip. CUDA and cuDNN (GPU acceleration): If you use NVIDIAGPU, you need to install CUDATool

Docker uses Linux kernel features to provide an efficient and isolated application running environment. Its working principle is as follows: 1. The mirror is used as a read-only template, which contains everything you need to run the application; 2. The Union File System (UnionFS) stacks multiple file systems, only storing the differences, saving space and speeding up; 3. The daemon manages the mirrors and containers, and the client uses them for interaction; 4. Namespaces and cgroups implement container isolation and resource limitations; 5. Multiple network modes support container interconnection. Only by understanding these core concepts can you better utilize Docker.

Enable PyTorch GPU acceleration on CentOS system requires the installation of CUDA, cuDNN and GPU versions of PyTorch. The following steps will guide you through the process: CUDA and cuDNN installation determine CUDA version compatibility: Use the nvidia-smi command to view the CUDA version supported by your NVIDIA graphics card. For example, your MX450 graphics card may support CUDA11.1 or higher. Download and install CUDAToolkit: Visit the official website of NVIDIACUDAToolkit and download and install the corresponding version according to the highest CUDA version supported by your graphics card. Install cuDNN library:

Python and JavaScript have their own advantages and disadvantages in terms of community, libraries and resources. 1) The Python community is friendly and suitable for beginners, but the front-end development resources are not as rich as JavaScript. 2) Python is powerful in data science and machine learning libraries, while JavaScript is better in front-end development libraries and frameworks. 3) Both have rich learning resources, but Python is suitable for starting with official documents, while JavaScript is better with MDNWebDocs. The choice should be based on project needs and personal interests.

When selecting a PyTorch version under CentOS, the following key factors need to be considered: 1. CUDA version compatibility GPU support: If you have NVIDIA GPU and want to utilize GPU acceleration, you need to choose PyTorch that supports the corresponding CUDA version. You can view the CUDA version supported by running the nvidia-smi command. CPU version: If you don't have a GPU or don't want to use a GPU, you can choose a CPU version of PyTorch. 2. Python version PyTorch

CentOS Installing Nginx requires following the following steps: Installing dependencies such as development tools, pcre-devel, and openssl-devel. Download the Nginx source code package, unzip it and compile and install it, and specify the installation path as /usr/local/nginx. Create Nginx users and user groups and set permissions. Modify the configuration file nginx.conf, and configure the listening port and domain name/IP address. Start the Nginx service. Common errors need to be paid attention to, such as dependency issues, port conflicts, and configuration file errors. Performance optimization needs to be adjusted according to the specific situation, such as turning on cache and adjusting the number of worker processes.

Efficiently process PyTorch data on CentOS system, the following steps are required: Dependency installation: First update the system and install Python3 and pip: sudoyumupdate-ysudoyuminstallpython3-ysudoyuminstallpython3-pip-y Then, download and install CUDAToolkit and cuDNN from the NVIDIA official website according to your CentOS version and GPU model. Virtual environment configuration (recommended): Use conda to create and activate a new virtual environment, for example: condacreate-n
