我是python的新手,一直致力於解析excel電子表格。我試圖確定一系列日期的特定分區的累計值。在迭代for循環時覆蓋所有值 - Python
我有一種感覺,我沒有正確理解邏輯流程,因爲不管我如何寫它,我總是以一個完全相同的值的字典結尾。在這一點上,我不明白爲什麼它是錯誤的,所以我不想寫它,而是想面對它。
的hoursAllocationDict樣子:
5-21-16
Zoning1: 0
Zoning2: 0
Zoning3: 0
5-22-16
Zoning1: 0
etc...
我RAWDATA看起來像一個列表的列表:
[0] NAME, data, data, data, DATE, data, HOURS, data, ZONING, data, data, data, etc.
[1] NAME, data, data, data, DATE, data, HOURS, data, ZONING, data, data, data, etc.
[2] NAME, data, data, data, DATE, data, HOURS, data, ZONING, data, data, data, etc.
我競選這一特定任務的代碼塊的樣子:
#Iterate over all dates - date is a tuple with 0 index being the date and 1 being a dict of zonings
for date in hoursAllocationDict.iteritems():
#Iterate over each row
for row in rawData:
#If cell is not empty or blank AND if date cell equals iterator date
if rawData[row][23] and rawData[row][9] == date[0]:
#Use re.search to match possible zoning in zoning column (found in string of otherwise irrelevant data)
if findZoningInCell(rawData[row][23], zoningsDict):
#Store whatever subjoining we find
subZoning = findZoningInCell(rawData[row][23], zoningsDict)
#rawData[row][18] references a value of hours related to zoning
#Accumulate x.x hrs in hoursAllocationDict -> date -> subjoining
hoursAllocationDict[rawData[row][9]][subZoning] += rawData[row][18]
hoursAllocationDict的最終狀態如下所示:
'10-29-15' : 'Zoning1': 52.0, 'Zoning2': 100.08333333333333, 'Zoning3': 128.0, 'Zoning4': 594.0, etc...
'10-30-15' : 'Zoning1': 52.0, 'Zoning2': 100.08333333333333, 'Zoning3': 128.0, 'Zoning4': 594.0, etc...
'10-31-15' : 'Zoning1': 52.0, 'Zoning2': 100.08333333333333, 'Zoning3': 128.0, 'Zoning4': 594.0, etc...
....

所以我不知何故每次迭代更新字典的所有鍵的所有值,但我不知道如何。我已經重寫了幾次,現在可以利用。
