python 3.7环境安装并使用csv

因为调换需要，进了另外一个维护组，需要用python解析excel csv，所以就下载了一下他们需要的python3.7

如何做呢，看步骤

1.去官网

2.找版本

3.下源码

4.解压出来进入文件夹

开始编译安装

cd Python-3.7.11/
./configure --enable-optimizations
sudo make
sudo make install
python3.7 -V

好了，返回 Python 3.7.11

版本有了

随手写个小代码 py_csv.py

import csv

headers = ['class','name','sex','height','year']

rows = [
        [1,'xiaoming','male',168,23],
        [1,'xiaohong','female',162,22],
        [2,'xiaozhang','female',163,21],
        [2,'xiaoli','male',158,21]
    ]

with open('test.csv','w') as f:
    f_csv = csv.writer(f)
    f_csv.writerow(headers)
    f_csv.writerows(rows)

python3.7 py_csv.py 执行完毕

发现文件有了

打开一看 有了
