Python xlsxwriter,更改工作表中所有行的行高,以下是可用的,但适用于单行

worksheet.set_row(0, 20)  # Set the height of Row 1 to 20.

我将列表的每个元素转换为元组,如下所示:

l = ['abc','xyz','test']

转换为元组列表:

newl = [('abc',),('xyz',),('test',)]

实际上我用这样的键有词,所以为了搜索目的,我需要有这些.

SQLServer.java:66: warning: [deprecation] readLine() in DataInputStream has been     deprecated
                            query = in.readLine();
