在ubuntu下,新建.csv文件的方法是使用LibreOffice来创建一个数据表,然后我们把表格存储为.csv的格式:

“Save as”菜单把我们的表格存为一个CSV的文件格式:命名为csvData.csv:

 

name,num
zhangsan,123
lisi,456
wangwu,789

 

然后通过程序读写,如下图所示:

  

python读取并写入csv文件_pythonpython读取并写入csv文件_ubuntu_02
 1 # -- coding: utf-8 --
 2 
 3 import csv 
 4  
 5 #读取csv文件方式1
 6 csvFile = open("csvData.csv", "r")
 7 reader = csv.reader(csvFile)  # 返回的是迭代类型
 8 data = []
 9 for item in reader:
10     print(item)
11     data.append(item)
12                   
13 print(data)
14 csvFile.close()
15 
16 
17 #读取csv文件方式2
18 with open("csvData.csv", "r") as csvfile:
19     reader2 = csv.reader(csvfile)
20     for item2 in reader2:
21         print(item2)
22 csvFile.close()
23 ~

输出结果:

['name', 'num']
['zhangsan', '123']
['lisi', '456']
['wangwu', '789']
[['name', 'num'], ['zhangsan', '123'], ['lisi', '456'], ['wangwu', '789']]
['name', 'num']
['zhangsan', '123']
['lisi', '456']
['wangwu', '789']
