Python学习笔记之os模块使用总结
代码如下:
#!/usr/bin/env python
##-*- coding: utf-8 -*-
import os
print "n欢迎大家跟我一起学Python";
system=os.name; #获取系统的类型
if(system=="nt"):
print "您使用的操作系统是windows";
print "使用windows表示的特定路径分割符是 "+os.sep; #获取系统的分隔符
print "您的电脑系统的终止符效果"+os.linesep; #获取系统换行符
else:
print "您使用的操作系统是Linux";
print "使用windows表示的特定路径分割符是 "+os.sep;
print "您的电脑系统的终止符是"+os.linesep;
path=os.getcwd(); #获得当前目录
print "您运行本程序所在目录是 "+path;
print "你电脑的Path环境变量为 "+os.getenv("Path"); #获取环境变量的值os.putenv(key,value)可以设置环境变量的值
print "你当前文件夹中的文件有:";
print os.listdir(path); #获取文件夹中的所有文件
if(os.path.exists("test.txt")): #判断文件是否存在
os.remove("test.txt") #删除指定文件
print "n删除成功";
else:
print "n文件不存在";
print "咱们来删除一个文件,删除后的结果:";
print os.listdir(path);
print "n查看您的ip:n";
print os.system("ipconfig"); #执行系统命令
filepath1="C:Python27";
filepath2="C:Python27os.py";
if(os.path.isfile(filepath2)): #判断是不是文件
print filepath2+"是一个文件";
if(os.path.isfile(filepath1)):
print filepath1+"是一个文件";
else:
print filepath1+"不是一个文件";
name="os.py";
print "本程序的大小为";
print os.path.getsize(name); #获取文件大小
name=os.path.abspath(name); #获取文件的绝对路径
print "本程序的绝对路径是"+name;
print "本程序的路径的文件名分别为:";
print os.path.split(name); #将文件名和路径分开
files=os.path.splitext(name); #将文件名和扩展分开
print "本程序的扩展为"+files[1];
print "本程序的文件名为"+os.path.basename(name);#获取文件的名字
print "本程序的路径为"+os.path.dirname(name);#获取文件的路径

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.

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.

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.

MinIO Object Storage: High-performance deployment under CentOS system MinIO is a high-performance, distributed object storage system developed based on the Go language, compatible with AmazonS3. It supports a variety of client languages, including Java, Python, JavaScript, and Go. This article will briefly introduce the installation and compatibility of MinIO on CentOS systems. CentOS version compatibility MinIO has been verified on multiple CentOS versions, including but not limited to: CentOS7.9: Provides a complete installation guide covering cluster configuration, environment preparation, configuration file settings, disk partitioning, and MinI

PyTorch distributed training on CentOS system requires the following steps: PyTorch installation: The premise is that Python and pip are installed in CentOS system. Depending on your CUDA version, get the appropriate installation command from the PyTorch official website. For CPU-only training, you can use the following command: pipinstalltorchtorchvisiontorchaudio If you need GPU support, make sure that the corresponding version of CUDA and cuDNN are installed and use the corresponding PyTorch version for installation. Distributed environment configuration: Distributed training usually requires multiple machines or single-machine multiple GPUs. Place

When installing PyTorch on CentOS system, you need to carefully select the appropriate version and consider the following key factors: 1. System environment compatibility: Operating system: It is recommended to use CentOS7 or higher. CUDA and cuDNN:PyTorch version and CUDA version are closely related. For example, PyTorch1.9.0 requires CUDA11.1, while PyTorch2.0.1 requires CUDA11.3. The cuDNN version must also match the CUDA version. Before selecting the PyTorch version, be sure to confirm that compatible CUDA and cuDNN versions have been installed. Python version: PyTorch official branch

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.
