Python xlwings函数查找包含数据的最后一行

我正在尝试查找包含数据的列中的最后一行。要替换vba函数，请执行以下操作：

LastRow=sht.Cells（sht.Rows.Count，“A”）.End（xlUp）.Row

我正在尝试这一点，但这会拉入Excel中的所有行。我怎么才能坐到最后一排呢

from xlwings import Workbook, Range
wb = Workbook()
print len(Range('A:A'))

import xlwings
workbook_all = xlwings.Book(r'path.xlsx')
objectiveSheet = workbook_all .sheets['some_sheet']
# lastCellContainData(), inspired of Stefan's answer.
def lastCellContainData(objectiveSheet,lastRow=None,lastColumn=None):
    lastRow = objectiveSheet.cells.last_cell.row if lastRow==None else lastRow
    lastColumn = objectiveSheet.cells.last_cell.column if lastColumn==None else lastColumn
    lastRows,lastColumns = [],[]
    for col in range(1,lastColumn):
        lastRows.append(objectiveSheet.range((lastRow, col)).end('up').row)
        # extract last row of every column, then max(). Or you can compare the next 
        # column's last row number to the last column's last row number. Here you get
        # the last row with data, you can also go further get the last column with data:
    for row in range(1,lastRow):
        lastColumns.append(objectiveSheet.range((row, lastColumn)).end('left').column)
    return max(lastRows),max(lastColumns)
    
lastCellContainData(objectiveSheet,lastRow=5000,lastColumn=300)

试试这个：

import xlwings as xw

cellsDown = xw.Range('A1').vertical.value

cellsRight = xw.Range('A1').horizontal.value

print len(cellsDown)

print len(cellsRight)

您可以尝试使用

方向

，从最底部开始，然后向上移动：

import xlwings
from xlwings.constants import Direction
wb = xlwings.Workbook(r'data.xlsx')
print(wb.active_sheet.xl_sheet.Cells(65536, 1).End(Direction.xlUp).Row)

这与crazymachu的答案非常相似，只是被一个函数所包围。从xlwings的0.9.0版开始，您可以执行以下操作：

import xlwings as xw

def lastRow(idx, workbook, col=1):
    """ Find the last row in the worksheet that contains data.

    idx: Specifies the worksheet to select. Starts counting from zero.

    workbook: Specifies the workbook

    col: The column in which to look for the last cell containing data.
    """

    ws = workbook.sheets[idx]

    lwr_r_cell = ws.cells.last_cell      # lower right cell
    lwr_row = lwr_r_cell.row             # row of the lower right cell
    lwr_cell = ws.range((lwr_row, col))  # change to your specified column

    if lwr_cell.value is None:
        lwr_cell = lwr_cell.end('up')    # go up untill you hit a non-empty cell

    return lwr_cell.row

直观地说，函数从查找工作簿中最右下角的单元格开始。然后，它移动到所选列，然后向上移动，直到它到达第一个非空单元格。

可以使用通过api属性公开的VBA查找函数（使用它查找任何带星号的内容，并从第一个单元格开始搜索）

例如：

row_cell = s.api.Cells.Find(What="*",
                   After=s.api.Cells(1, 1),
                   LookAt=xlwings.constants.LookAt.xlPart,
                   LookIn=xlwings.constants.FindLookIn.xlFormulas,
                   SearchOrder=xlwings.constants.SearchOrder.xlByRows,
                SearchDirection=xlwings.constants.SearchDirection.xlPrevious,
                       MatchCase=False)

column_cell = s.api.Cells.Find(What="*",
                      After=s.api.Cells(1, 1),
                      LookAt=xlwings.constants.LookAt.xlPart,
                      LookIn=xlwings.constants.FindLookIn.xlFormulas,
                      SearchOrder=xlwings.constants.SearchOrder.xlByColumns,
                      SearchDirection=xlwings.constants.SearchDirection.xlPrevious,
                      MatchCase=False)

print((row_cell.Row, column_cell.Column))

这里列出的其他方法似乎不需要数据之间有空的行/列

综合以上答案，您可以在一行中完成：

wb.sheet.range(column + last cell value).Get End of section going up[non blank assuming the last cell is blank].row

示例代码：

import xlwings as xw
from xlwings import Range, constants

wb = xw.Book(r'path.xlsx')
wb.sheets[0].range('A' + str(wb.sheets[0].cells.last_cell.row)).end('up').row

---

我们可以使用范围对象查找最后一行和/或最后一列：

import xlwings as xw

# open raw data file
filename_read = 'data_raw.csv'
wb = xw.Book(filename_read)
sht = wb.sheets[0]

# find the numbers of columns and rows in the sheet
num_col = sht.range('A1').end('right').column
num_row = sht.range('A1').end('down').row

# collect data
content_list = sht.range((1,1),(num_row,num_col)).value
print(content_list)

python 3.6、XL0.11

溶质1 要查找包含数据的最后一行，您应该在水平和垂直方向上进行一些工作。您必须遍历每一列以确定哪一行是最后一行

from xlwings import Workbook, Range
wb = Workbook()
print len(Range('A:A'))

import xlwings
workbook_all = xlwings.Book(r'path.xlsx')
objectiveSheet = workbook_all .sheets['some_sheet']
# lastCellContainData(), inspired of Stefan's answer.
def lastCellContainData(objectiveSheet,lastRow=None,lastColumn=None):
    lastRow = objectiveSheet.cells.last_cell.row if lastRow==None else lastRow
    lastColumn = objectiveSheet.cells.last_cell.column if lastColumn==None else lastColumn
    lastRows,lastColumns = [],[]
    for col in range(1,lastColumn):
        lastRows.append(objectiveSheet.range((lastRow, col)).end('up').row)
        # extract last row of every column, then max(). Or you can compare the next 
        # column's last row number to the last column's last row number. Here you get
        # the last row with data, you can also go further get the last column with data:
    for row in range(1,lastRow):
        lastColumns.append(objectiveSheet.range((row, lastColumn)).end('left').column)
    return max(lastRows),max(lastColumns)
    
lastCellContainData(objectiveSheet,lastRow=5000,lastColumn=300)

我添加了lastRow和lastColumn。为了使程序更有效，您可以根据正在处理的数据的近似形状设置这些参数

解决方案2 xlwings很荣幸成为pywin32的包装器。我不知道你的情况是否允许使用键盘或鼠标。如果是这样，首先按住ctrl+tab键切换到工作簿，然后按住ctrl+a键选择包含数据的区域，然后调用

workbook\u all.selection.rows.count

另一种方式：

当您隐约知道数据右下角单元格的位置时，比如AAA10000，只需调用

objectiveSheet.range（'A1:'+'AAA10000'）.current\u region.rows.count

，目前还没有现成的实现。但你总是可以按照解释来解决问题。另外，请看Hi，在代码中添加一些解释，因为这有助于理解您的代码。只有代码的答案是不受欢迎的。最简单和最好的解决方案-thx
