python – 迭代工作表,行,列

前端之家收集整理的这篇文章主要介绍了python – 迭代工作表,行,列前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
我想使用openpyxl打印 python中特定列的所有数据(所有行)我正在以这种方式工作;
from openpyxl import load_workbook
workbook = load_workbook('----------/dataset.xlsx')
sheet = workbook.active  
for i in sheet:
   print(sheet.cell(row=i,column=2).value)

但它给出了

if row < 1 or column < 1:
TypeError: unorderable types: tuple() < int()

因为我在row = i中迭代.如果我使用sheet.cell(row = 4,column = 2).value它会打印cell的值.但是,我如何迭代所有文档?

在一些研究中,发现可以使用工作表名称获取数据.工作表1存在于.xlsx文件中,但其数据未打印.这段代码有什么问题吗?

workbook = load_workbook('---------------/dataset.xlsx')
print(workbook.get_sheet_names())
worksheet =workbook.get_sheet_by_name('Sheet1')
c=2
for i in worksheet: 
    d = worksheet.cell(row=c,column=2)
    if(d.value is None):
        return
    else:
        print(d.value)
    c=c+1

迭代工作簿中的所有工作表,例如:

for n,sheet in enumerate(wb.worksheets):
    print('Sheet Index:[{}],Title:{}'.format(n,sheet.title))

Output:

06001

迭代一个工作表中的所有行和列:

worksheet = workbook.get_sheet_by_name('Sheet')

for row_cells in worksheet.iter_rows():
    for cell in row_cells:
       print('%s: cell.value=%s' % (cell,cell.value) )

输出

<Cell Sheet.A1>: cell.value=²234
<Cell Sheet.B1>: cell.value=12.5
<Cell Sheet.C1>: cell.value=C1
<Cell Sheet.D1>: cell.value=D1
<Cell Sheet.A2>: cell.value=1234
<Cell Sheet.B2>: cell.value=8.2
<Cell Sheet.C2>: cell.value=C2
<Cell Sheet.D2>: cell.value=D2

迭代一行的所有列,例如row == 2:

for row_cells in worksheet.iter_rows(min_row=2,max_row=2):
    for cell in row_cells:
        print('%s: cell.value=%s' % (cell,cell.value) )

输出

<Cell Sheet.A2>: cell.value=1234  
<Cell Sheet.B2>: cell.value=8.2  
<Cell Sheet.C2>: cell.value=C2  
<Cell Sheet.D2>: cell.value=D2

迭代所有行,只有第2列:

for col_cells in worksheet.iter_cols(min_col=2,max_col=2):
    for cell in col_cells:
        print('%s: cell.value=%s' % (cell,cell.value))

输出

<Cell Sheet.B1>: cell.value=12.5
<Cell Sheet.B2>: cell.value=8.2
<Cell Sheet.B3>: cell.value=9.8
<Cell Sheet.B4>: cell.value=10.1
<Cell Sheet.B5>: cell.value=7.7

用Python测试:3.4.2 – openpyxl:2.4.1 – LibreOffice:4.3.3.2
