@ $TOC$ ( $python-base gammer learning(1): setting conda + Jupyter$ )

1:introduction

这部分是大学院课程复习部分，我会使用英文来书写，增加自己英语应用能力，让我们开始python 学习吧。！！！

people should constantly　improve themselves.

I ofter use Python in my work and studies , However I have not systematically learned Python grammear before.

this is something I wangt to change

I aim to learn Python grammar thoroughly and gain a deeper understanding of it

2:computer setting development environment

It is ver important to ensure that your computer settings and development environment are properly configured .

If the setup is in corret or complicated , Python may not work properly , and errors may occur

Therefore we need to make sure that our computer setings and development environment are correctly prepared

System Requirements

win : 10 /11
python 3.x

(1) open powershell or command Prompt

bash 复制代码

systeminfo

(2) check Python Version

this order is test python version , Use the following commands to check the installed Python version:

bash 复制代码

python --version 

python3 --version

(3) Check pip Version

this order is test pip version Use tis command to check the pip version

bash 复制代码

pip --version

3 introduction to Python and conda and Jupyter Notebook

(1) python

official website:

URL:https://www.python.org/

Python is widely used programming llanguage for developemnt ,data analysis and AI

(2) Anaconda

Anaconda

official documentation:
https://docs.conda.io/projects/conda/en/stable/

Anaconda is a distribution that simplifies package management and environment setup

it is very useful for beginners and data science workflows

(3) Jupyter Notebook

this section explains how to install jupyter Notebook

Open powershell or command prompt（run as administrator ）,then execute

bash 复制代码

conda install notebook

after installation , start jupyter Notebook:

bash 复制代码

jupyter notebook

(4) Recommendation

instead of intsalling packages in the base environment(c:\miniconda3),

it is better to create a new environment:

bash 复制代码

conda create -n myenv python=3.10 notebook
conda activate myenv
jupyter notebook

4 Function Testing

(1) Create a new file

create a new notebook file in jupyter

(2) test code

Write a simple test program.

(4) running code

Shift + Enter to run the code.

5 problom

(1) Cannot Install Jupyter

Problem:

bash 复制代码

conda install notebook → cannot find or install

solution:

Run as Administrator
Or create a new environment

(2）cannot open jupyter page

sometimes you may see an error when opening the browser

solution:

open manually in your brower:

bash 复制代码

http://localhost:8888

6 Summary

this is the beginning of my pthon learning journey.

by setting up the environment correctly , I can focus on learning python more efficiently.

I will continue improving my skills step by step.
