Dynamicaly在Excel工作簿中從表格構建Python列表

Question

我試圖壓縮一些先前在python中編寫的代碼。我有一些在Excel工作簿中循環查找表的代碼。大約有20張工作簿中包含查找表。我想遍歷每個查找表中的值並將它們添加到他們自己的列表中。我現有的代碼如下所示：

test1TableList = [] 
for row in arcpy.SearchCursor(r"Z:\Excel\LOOKUP_TABLES.xlsx\LookupTable1$"): 
    test1TableList.append(row.Code) 

test2TableList = [] 
for row in arcpy.SearchCursor(r"Z:\Excel\LOOKUP_TABLES.xlsx\LookupTable1$"): 
    test2TableList.append(row.Code) 

test3TableList = [] 
for row in arcpy.SearchCursor(r"Z:\Excel\LOOKUP_TABLES.xlsx\LookupTable1$"): 
    test3TableList.append(row.Code) 

test4TableList = [] 
for row in arcpy.SearchCursor(r"Z:\Excel\LOOKUP_TABLES.xlsx\LookupTable1$"): 
    test4TableList.append(row.Code) 

test5TableList = [] 
for row in arcpy.SearchCursor(r"Z:\Excel\LOOKUP_TABLES.xlsx\LookupTable1$"): 
    test5TableList.append(row.Code) 

內容非常重要

我想壓縮代碼（也許在一個函數）。

問題需要解決：

1. 表的名稱都不同。我需要遍歷Excel工作簿中的每個工作表，以便a）抓取工作表對象和b）使用工作表名稱作爲python列表變量名稱的一部分
2. 我希望每個列表都留在內存中以供進一步使用代碼

我一直是這樣的，它的工作，但蟒蛇名單變量似乎並沒有留在記憶：

import arcpy, openpyxl 
from openpyxl import load_workbook, Workbook 

wb = load_workbook(r"Z:\Excel\LOOKUP_TABLES.xlsx") 

for i in wb.worksheets: 

    filepath = r"Z:\Excel\LOOKUP_TABLES.xlsx" + "\\" + i.title + "$" 
    varList = [] 
    with arcpy.da.SearchCursor(filepath, '*') as cursor: 
     for row in cursor: 
      varList.append(row[0]) 

    # This is the area I am struggling with. I can't seem to find a way to return 
    # each list into memory. I've tried the following code to dynamically create 
    # variable names from the name of the sheet so that each list has it's own 
    # variable. After the code has run, I'd just like to set a print statement 
    # (i.e. print variablename1) which will return the list contained in the variable 
    newList = str(i.title) + "List" 
    newList2 = list(varList) 
    print newList + " = " + str(newList2) 

我一直工作在這一段時間而且我毫不懷疑，在這一點上，我正在考慮我的解決方案，但我處於封鎖狀態。任何建議，歡迎！

而不必養殖列表，使用字典，每片收集的數據：如果

import arcpy 
from openpyxl import load_workbook 

wb = load_workbook(r"Z:\Excel\LOOKUP_TABLES.xlsx") 

sheets = {} 
for i in wb.worksheets: 
    filepath = r"Z:\Excel\LOOKUP_TABLES.xlsx" + "\\" + i.title + "$" 
    with arcpy.da.SearchCursor(filepath, '*') as cursor: 
     sheets[i.title] = [row[0] for row in cursor] 

print sheets

不知道它是最適合你的，但你可以使用大熊貓導入你的牀單成一個數據幀。

from pandas.io.excel import ExcelFile 
filename = 'linreg.xlsx' 
xl = ExcelFile(filename) 

for sheet in xl.sheet_names: 
    df = xl.parse(sheet) 
    print df
