使用Python在Excel中进行字符串替换

Question

我想把 % 符号去掉，并用一个字符串替换它；同时把空格去掉，用下划线替换。

这是我到目前为止做的：

# Open Excel file from a user imput
import xlrd, xlwt
filename = raw_input("Enter Excel file name with extension (.xls) and path")
oldbook = xlrd.open_workbook(filename)
newbook = xlwt.Workbook()

# For all the sheets in the workbook
for sheetname in oldbook.sheet_names():
    oldsheet = oldbook.sheet_by_name(sheetname)
    newsheet = newbook.add_sheet(sheetname)

    # For all the rows and all the columns in an excel
    for ii in range(oldsheet.nrows):
        for jj in range(oldsheet.ncols):
            # Replace
            range.replace("%", "Perc")

# Save the file in a desired location with the desired name
savelocation = raw_input("Enter a new path and file name with extension (.xls) to save the new Excel spread sheet ")
newbook.save(savelocation)

有一个建议，就是把单元格的数据先读成一个字符串，然后再进行处理。

可以试试这个方法：（很遗憾我现在无法运行它）

# Open Excel file from a user imput
import xlrd, xlwt
filename = raw_input("Enter Excel file name with extension (.xls) and path")
oldbook = xlrd.open_workbook(filename)
newbook = xlwt.Workbook()

# For all the sheets in the workbook
for sheetname in oldbook.sheet_names():
    oldsheet = oldbook.sheet_by_name(sheetname)
    newsheet = newbook.add_sheet(sheetname)

    # For all the rows and all the columns in an excel
    for ii in range(oldsheet.nrows):
        for jj in range(oldsheet.ncols):
            # Replace
            CellString=str(oldsheet.cell(ii, jj).Value)
            CellString=CellString.replace("%", "Perc")
            CellString=CellString.replace(" ", "_")
            newsheet.write(ii, jj, CellString)
# Save the file in a desired location with the desired name
savelocation = raw_input("Enter a new path and file name with extension (.xls) to save the new Excel spread sheet ")
newbook.save(savelocation)
