Python漂亮表格示例

Question

我有一个PrettyTable的例子，这个例子是从文档中复制而来的，但是我遇到了一个错误。

#!/usr/bin/python

from prettytable import PrettyTable
import csv

x = PrettyTable(["City name", "Area", "Population", "Annual Rainfall"])
x.align["City name"] = "l" # Left align city names
x.padding_width = 1 # One space between column edges and contents (default)
x.add_row(["Adelaide",1295, 1158259, 600.5])
x.add_row(["Brisbane",5905, 1857594, 1146.4])
x.add_row(["Darwin", 112, 120900, 1714.7])
x.add_row(["Hobart", 1357, 205556, 619.5])
x.add_row(["Sydney", 2058, 4336374, 1214.8])
x.add_row(["Melbourne", 1566, 3806092, 646.9])
x.add_row(["Perth", 5386, 1554769, 869.4])
print x

我收到的错误信息如下。

Traceback (most recent call last):
File "/home/definity/Desktop/Cloud/code/Python/Finacial.py", line 3, in <module>
from prettytable import PrettyTable
File "/usr/local/lib/python2.7/dist-packages/prettytable-0.7.2-     py2.7.egg/prettytable.py", line 35, in <module>
import csv
File "/home/definity/Desktop/Cloud/code/Python/csv.py", line 6, in <module>
reader = csv.reader(ifile)
AttributeError: 'module' object has no attribute 'reader'

第一个示例为什么会出现错误？

- Definity

Answer 1

您可能有一个名为csv.py的文件与您的Finacial.py脚本在一起，这会使内置的csv模块失效 - 因此导致其导入（更准确地说是属性访问）失败。

它可能是/home/definity/Desktop/Cloud/code/Python/csv.py，但也可能是/home/definity/Desktop/Cloud/code/Python/csv.pyc，甚至是一个csv文件夹。
