Python将list元素转存为CSV文件的实现

list=[[1,2,3],[4,5,6],[7,9,9]]
list.to_csv('e:/testcsv.csv',encoding='utf-8')

import pandas as pd

list=[[1,2,3],[4,5,6],[7,9,9]]
# 下面这行代码运行报错
# list.to_csv('e:/testcsv.csv',encoding='utf-8')
name=['one','two','three']
test=pd.DataFrame(columns=name,data=list)#数据有三列，列名分别为one,two,three
print(test)
test.to_csv('e:/testcsv.csv',encoding='gbk')

import pandas as pd

list=[[1,2,3],[4,5,6],[7,9,9]]
name=['one','two','three']
name2=['a','b','c']
test=pd.DataFrame(columns=name,index=name2,data=list)
print(test)
test.to_csv('e:/testcsv.csv',encoding='gbk')
