使用Python读取CSV文件 [英] Reading a CSV file using Python
本文介绍了使用Python读取CSV文件的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
请告诉我这个代码有什么问题,它给出一个错误
import csv
with open some csv','rb')as f:
reader = csv.reader(f)
读取行:
print row
解决方案您使用的是哪个版本的Python?
with 语句在2.6中是新的 - 如果你使用2.5,你需要从__future__ import with_statement
中得到。如果你使用的Python比2.5大,那么没有
和
语句,所以只需写:import csv
f = open('some.csv','rb')
reader = csv.reader(f)
读取器中的行:
print row
f.close()
更好的是更新到现代版本的Python ,但。 Python 2.5几乎在5年前发布,2.x行中的当前版本是2.7
please tell me what's the problem in this code it's giving an error
import csv with open('some.csv', 'rb') as f: reader = csv.reader(f) for row in reader: print row
解决方案Which version of Python are you using?
The
with
statement is new in 2.6 - if you're using 2.5 you needfrom __future__ import with_statement
. If you use a Python older than 2.5 then there's nowith
statement, so just write:import csv f = open('some.csv', 'rb') reader = csv.reader(f) for row in reader: print row f.close()
It's really better to update to a modern version of Python, though. Python 2.5 was released almost 5 years ago, and the current version in the 2.x line is 2.7
