わかりました、答えは私が作成したこのばかげたラッパーだと思いますxlrd（または、あなたが自分で書いたものです！）。重要なのは、関数が一度に 1 行ずつリストに読み込むことと、Python のリストが入力された順序を記憶していることです。ラッパーは、Excel シート名をそのシートの行のリストにマップする辞書を生成します (ここでは、シートごとに 1 つのテーブルを想定しています。それ以外の場合は、一般化する必要があります)。各行は、キーが列名であるディクショナリです。
あなたのために、私はあなたのデータを読み込んでから、次のようなことをします（テストされていません）：
import see_below as sb
dict = sb.workbookToDict(your_file)
output = []
this_location = None
for row in dict[relevant_sheet_name]:
output_row = row
if row['Location'] is not None:
this_location = row['Location']
else:
output_row['Location'] = this_location
リスト内包表記で何かかわいいことができるかもしれませんが、今夜はそれでだますにはワインが多すぎました:)
リーダーのラッパーは次のとおりです。
import xlrd
def _isEmpty(_):
return ''
def _isString(element):
return element.value.encode('ascii', 'ignore')
def _isFloat(element):
return float(element.value)
def _isDate(element):
import datetime
rawDate = float(element.value)
return (datetime.datetime(1899, 12, 30) +
datetime.timedelta(days=rawDate))
def _isBool(element):
return element.value == 1
def _isExcelGarbage(element):
return int(element.value)
_options = {0: _isEmpty,
1: _isString,
2: _isFloat,
3: _isDate,
4: _isBool,
5: _isExcelGarbage,
6: _isEmpty}

dictionary. The output maps sheet names (keys) to a collection of dictionaries
(value).
