Python 如何将表格的列从CSV中移出？

我已经为CSV数据添加了新的标题（参数），新的参数必须进行计算，所以它需要保持为空。我需要将整个数据向右移动一列，但我不知道如何使用PythonV3.2 谁能帮帮我吗

因此，当我用excel打开python CSV文件时，它会给我类似的信息（超级简化版，我有数千行和数千列）

。

我想把这个改成；让P1空着

P1 P2 P3 P4 P5 ...

    1  2  3  4  
    1  2  3  4   
    1  2  3  4  

这是我到目前为止得到的代码。我只想将数据向右移动一列。谁能帮帮我吗？ 提前谢谢

    import csv

    # reads the input and spits out the output
    with open ('DownloadDB_CSV1.csv', 'r') as csvinput:
         with open ('outputCSV.csv', 'w', newline ='') as csvoutput:
             reader = csv.reader(csvinput, delimiter = ',')
            writer = csv.writer(csvoutput,  delimiter = ',')
    all = []
    row = next(reader)
    row.insert(0,'GenomePosition')
    all.append(row)



    for row in reader:
        all.append(row)
        contents = row[0::] # sepearte it to a variable
    writer.writerows(all)

---

要插入空列，您只需在每行中添加一个首字母

，

。这里有一些代码可以做到这一点-你甚至不需要CSV模块来完成它。从你的例子来看，我想你不想改变标题，对吧

分隔符=“，”
def添加_空（填充、输出文件）：
开放式（输出文件，“w”）作为输出：
以open（infle，“r”）作为inf：
line=inf.readline（）#复制标题
输出写入（行）
尽管如此：
line=inf.readline（）
如果行=“”：中断#EOF
输出写入（“+”分隔符+行）
def main（）：
添加_empty（“test.csv”、“testshift.csv”）
返回0
如果uuuu name uuuuuu='\uuuuuuu main\uuuuuuu'：
main（）

怎么做？你是说excel？我需要将python脚本中的数组转换为excel中的数组。好的，您使用的是正确的数组，但您仍然从一开始就编写它。所以我的问题是：exel中的空collumn是什么？你为什么不写呢？我是python新手，我一直在用matlab做所有的矩阵运算，，，所以我想不出任何方法将这些数据移动到下一列，，，，，，你想要我做什么新列，一个空字符串？谢谢，这正是我需要的！
