Python讀寫csv檔案

標籤：

1. 寫入並產生csv檔案代碼：

 

  
# coding: utf-8
  

  
import csv
  

  
csvfile = file(‘csv_test.csv‘, ‘wb‘)
  
writer = csv.writer(csvfile)
  
writer.writerow([‘姓名‘, ‘年齡‘, ‘電話‘])
  

  
data = [
  
    (‘小河‘, ‘25‘, ‘1234567‘),
  
    (‘小芳‘, ‘18‘, ‘789456‘)
  
]
  
writer.writerows(data)
  

  
csvfile.close()
 

• wb中的w表示寫入模式，b是檔案模式
• 寫入一行用writerow
• 多行用writerows

2. 讀取csv檔案代碼：

 

  
# coding: utf-8
  

  
import csv
  

  
csvfile = file(‘csv_test.csv‘, ‘rb‘)
  
reader = csv.reader(csvfile)
  

  
for line in reader:
  
    print line
  

  
csvfile.close() 
 

運行結果：

[‘\xe5\xb0\x8f\xe6\xb2\xb3‘, ‘25‘, ‘1234567‘]
  
[‘\xe5\xb0\x8f\xe8\x8a\xb3‘, ‘18‘, ‘789456‘]
