蟒蛇CSV不解析分隔符

Question

我试图做一个简单的CSV使用python分析，我有以下代码：

print csvdata 
print "\n" 
csvparsed = csv.reader(csvdata) 

for row in csvparsed: 
    print row 

然而，似乎所分析的数据中的每一行是单个字符，而不是用逗号分隔。我在这里错过了什么吗？这是我得到的输出：

Restaurant ID,2,, 
,,, 
Menu Name,Breakfast Menu,, 

['R'] 
['e'] 
['s'] 
['t'] 
['a'] 
['u'] 
['r'] 
['a'] 
['n'] 
['t'] 
[' '] 
['I'] 
['D'] 
['', ''] 
['2'] 
['', ''] 
['', ''] 
[] 
['', ''] 
['', ''] 
['', ''] 
[] 
['M'] 
['e'] 
['n'] 
['u'] 
[' '] 
['N'] 
['a'] 
['m'] 
['e'] 
['', ''] 
['B'] 
['r'] 
['e'] 
['a'] 
['k'] 
['f'] 
['a'] 
['s'] 
['t'] 
[' '] 
['M'] 
['e'] 
['n'] 
['u'] 
['', ''] 
['', ''] 

Answer 1

csv.reader是为了给予在文本行的迭代器，这是一个开放的文件是如何工作的。你给它一个字符串，当你迭代它时会产生字符。如果您从文件中获取数据，只需将打开的文件提供给csv.reader，则不要先阅读文本。

如果你确实已经在一个字符串文本，然后使用此：

csv.reader(csvdata.splitlines()) 

Answer 2

这可能是更接近你想要做什么：

csvparsed = csv.reader(open('csvdata', 'r')) 

for row in csvparsed: 
    print row 

有了这个，和您的示例数据在一个文件中，我得到这个输出：

['Restaurant ID', '2', '', ''] 
['', '', '', ''] 
['Menu Name', 'Breakfast Menu', '', '']
