如何使用xlsWriterr逐行获取输出

Question

我只是从循环中逐行打印，我的输出是这样的：

['    4.0\n', '   17.2\n', '    7.0\n']   
['    0.0\n']
['    4.0\n', '   16.7\n', '    4.0\n']
['    4.0\n', '   16.7\n', '    4.0\n']
['    4.0\n', '   16.7\n', '    4.0\n']
['    4.0\n', '   16.7\n', '    4.0\n']
['    4.0\n', '   16.4\n', '    4.0\n']

但是在我的excel输出中我只是得到这样的第一行：

我的预期结果如下：

我目前的代码在这里：

count = 0   
DataList = []                                               
for line, file in enumerate(PM2Line):       
    if POA in file: 
        DataList.append(file[32:50])                                
print DataList #--> this will print the list of output      
worksheet.write_column('A1', DataList) #--> My problem is just getting first line.  
workbook.close()

任何建议或意见。

问题是您在每次迭代中使用新值覆盖列。您的代码应该看起来像 -

#some loop
    count = 0   
    DataList = []                                               
    for line, file in enumerate(PM2Line):       
        if POA in file: 
            DataList.append(file[32:50])                                
    print DataList #--> this will print the list of output      
    worksheet.write_column('A1', DataList) #--> My problem is just getting first line.  
    workbook.close()

您应该将DataList保留在外部循环之外，并且只在该循环之外更新工作表。示例 -

#open worksheet here instead of inside the loop.
DataList = []
#some loop
    count = 0                                              
    for line, file in enumerate(PM2Line):       
        if POA in file: 
            DataList.append(file[32:50])                                
    print DataList     
worksheet.write_column('A1', DataList)
workbook.close()
