如何用 Python 替换多个 excel 工作表中的 [cell] 内容？

Question

我有一个 Excel 表格，包含不同的单位值，例如“百”和“千”。

现在，我想将所有“千”改为“百”，这意味着原始单元格值将 [cell] 乘以 10。

我用VBA解决了这个问题，我想知道如何用python解决这个问题？

VBA 像这样：

Sub changecell()
Dim rng As Range
Dim i, t
Set rng = Sheet1.Range("b3:c5")
For Each i In rng
    t = t + 1
    If Not i Is Nothing Then
        If Right(i, 4) = "sand" Then
        rng(t) = Left(i, Len(i) - 8) * 10 & "hundred"
        End If
    End If
Next
End Sub

如何使用 python 从多个 excel 表中替换这些 [单元格]？

Answer 1

如果您需要在 Python 中执行此操作，请使用 pandas

但此 VBA 将在当前工作簿的所有工作表中执行替换：

Option Explicit

Public Sub GlobalReplaceThousandToHundred()
    Dim ws As Worksheet, ur As Variant, r As Long, c As Long, sz As Long

    Const STR1 = "thousand"
    Const STR2 = "hundred"

    sz = Len(STR1)

    For Each ws In ThisWorkbook.Worksheets
        ur = ws.UsedRange
        For r = LBound(ur) To UBound(ur)
            For c = LBound(ur, 2) To UBound(ur, 2)
                If Not IsError(ur(r, c)) Then
                    If LCase(Right(ur(r, c), sz)) = STR1 Then
                        ur(r, c) = Left(ur(r, c), Len(ur(r, c)) - sz) & STR2
                    End If
                End If
            Next
        Next
        ws.UsedRange = ur
    Next
End Sub

将你的 excel 表保存为 csv 文件，然后试试这个：

import csv 


with open('path_name_to_new_file', 'w', newline='') as newfile:
    with open('path_name_to_original_file', newline='') as original:
        writer = csv.writer(newfile, delimiter=',')
        reader = csv.reader(original, delimiter=',')
        for row in reader: 
            row[1] = row[1] * 10
            row[2] = row[2] * 10
            writer.writerow(row)

编辑：

所以，您有数百个 excel 文件...而不是所有列。未经测试的代码：

import pandas

 def test(cell):
    t = str(cell).split(' ')
    t = t[1] if len(t[1]) = 2 else None
    if t == 'thousand':
       return float(cell)*10
    else:
       return cell

excel_file_names = [##make a list of your file names##]
for file in excel_file_names:
    df = pandas.read_excel(file)
    for index,row in df.iterrows():
        row['2016'] = test(row['2016'])
        row['2015'] = test(row['2015'])

    writer = pd.ExcelWriter()
    df.to_excel(writer,'Sheet1')
    writer.save(file + '_modified')
