Question

我是python的新手，需要你的帮助。我正在尝试使用pyxl编写在excel中迭代特定列的代码

V = |(P5->P8 X P5->P6) * P5->P1|
P1 = ( [-17/12] , [11/36], [-65/36])
P5 = ([-11/12], [-7/36], [-47/36])
P6 = ([-2/3],[-1/9],[-8/9])
P8 = ([-5/4],[-1/12],[-17/12])`

在上面的示例中，我必须转到第J列并显示列中的所有值。

请帮我解决这个问题。

另外，我在excel表中重复了相同的列名。例如＆＃34; Sample＆＃34;列名在B2和J2中都可用。但是我想得到J2的所有列信息。

请让我知道如何解决这个问题......

谢谢..请回复

由于你是python的新手，你应该learn to read the documentation。有大量的模块可供使用，如果您先付出努力，它对您来说会更快，对我们其他人来说也更容易。

import openpyxl
from openpyxl.utils import cell as cellutils

## My example book simply has "=Address(Row(),Column())" in A1:J20

## Because my example uses formulae, I am loading my workbook with
## "data_only = True" in order to get the values; if your cells do not
## contain formulae, you can omit data_only
workbook = openpyxl.load_workbook("workbook.xlsx", data_only = True)
worksheet = workbook.active
## Alterntively: worksheet = workbook["sheetname"]


## A container for gathering the cell values
output = []

## Current Row = 2 assumes that Cell 1 (in this case, J1) contains your column header
## Adjust as necessary
column = cellutils.column_index_from_string("J")
currentrow = 2

## Get the first cell
cell = worksheet.cell(column = column, row = currentrow)

## The purpose of "While cell.value" is that I'm assuming the column
## is complete when the cell does not contain a value

## If you know the exact range you need, you can either use a for-loop,
## or look at openpyxl.utils.cell.rows_from_range
while cell.value:
    ## Add Cell value to our list of values for this column
    output.append(cell.value)

    ##  Move to the next row
    currentrow += 1

    ## Get that cell
    cell = worksheet.cell(column = column, row = currentrow)


print(output)
""" output: ['$J$2', '$J$3', '$J$4', '$J$5', '$J$6', '$J$7',
            '$J$8', '$J$9', '$J$10', '$J$11', '$J$12', '$J$13', '$J$14',
            '$J$15', '$J$16', '$J$17', '$J$18', '$J$19', '$J$20']
