python删除表 python删除表格等于0的列

通过python查找第31行从第2列到14列的数字，如果数字为0，则删除掉。

方法1：直接赋值为空值

import numpy as np
def del_0():
   for i in range(2,14):
      cell_value =sheet1.cell(row=31, column=i).value
      if cell_value == 0:
         sheet1.cell(31, i).value=" "

方法：直接赋值为None

import numpy as np
def del_0():
   for i in range(2,14):
      cell_value =sheet1.cell(row=31, column=i).value
      if cell_value == 0:
         sheet1.cell(31, i).value=None

方法3：导入numpy，赋值为np.nan

import numpy as np
def del_0():
   for i in range(2,14):
      cell_value =sheet1.cell(row=31, column=i).value
      if cell_value == 0:
         sheet1.cell(31, i).value=np.nan
