想要用python處理csv檔案。

去查了下，python中本身就自帶csv模組。

然後參考線上手冊：

去試試。

【用python生成csv】

1. 按照手冊的例子，試了試：

然後生成的檔案，原始資料為：

然後用excel開啟結果為：

很明顯，不是想要的結果，因為只是一列，實際應該是6列才對。

2. 然後折騰了一下之後，參考手冊的說明：

csv.writer(csvfile[, dialect=’excel’][, fmtparam])

Return a writer object responsible for converting the user’s data into delimited strings on the given file-like object. csvfile can be any object with a write() method. If csvfile

 is a file object, it must be opened with the ‘b’ flag on platforms where that makes a difference. An optional dialect parameter can be given which is used to define a set of parameters specific to a particular CSV dialect. It may be an instance of a subclass of the Dialect class or one of the strings returned by the list_dialects() function. The other optional fmtparam keyword arguments can be given to override individual formatting parameters in the current dialect. For full details about the dialect and formatting parameters, see section Dialects and Formatting Parameters. To make it as easy as possible to interface with modules which implement the DB API, the value None is written as the empty string. While this isn’t a reversible transformation, it makes it easier to dump SQL NULL data values to CSV files without preprocessing the data returned from a cursor.fetch* call. All other non-string data are stringified with str() before being written.
