Question

我正在尝试使用python进行简单的csv解析，我有以下代码：

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

for row in csvparsed:
    print row

但是，似乎解析数据的每一行都是单个字符，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意味着在文本行上给出一个迭代器，这就是打开文件的工作方式。你给了它一个字符串，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，不要先阅读文本。

如果你确实已经在字符串中包含了文本，那么请使用：

csv.reader(csvdata.splitlines())

Answer 2

这可能更接近你想要做的事情：

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

for row in csvparsed:
    print row

有了这个，你的样本数据在一个文件中，我得到了这个输出：

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

python csv没有解析分隔符
