以前在作一個excel的簡單教程的時候:
B站的一個Excel簡單教程python
當時演示應該把交叉表(圖1)轉換成數據表格(圖2)的形式。app
可是在excel裏沒有直接實現這個需求的函數,R的tidyr包有一個spread能夠實現這功能,可是,畢竟是R。ide
python一樣能夠實現這個需求,藉助openpyxl這個包和excel互動,而後用一點代碼就能夠完成了:函數
from openpyxl import Workbook,load_workbook from openpyxl.utils import get_column_letter wb = load_workbook('測試.xlsx') ws = wb.active rcList = tuple(ws.rows) print(rcList) def spreadIt(rcList,rowVarName='var1',colVarName='var2',cellVarName='var3'): rLength = len(rcList) cLength = len(rcList[0]) rst = [[rowVarName,colVarName,cellVarName]] for i in range(1,rLength): for j in range(1,cLength): rst.append([rcList[i][0].value, rcList[0] [j].value, rcList[i][j].value]) return rst def write2Sheet(spreaded,worksheet): for i in range(len(spreaded)): for j in range(len(spreaded[0])): worksheet["%s%d"%(get_column_letter(j+1),i+1)]=spreaded[i][j] wbNew = Workbook() wsNew = wbNew.active write2Sheet(spreadIt(rcList,rowVarName='節數',colVarName='星期',cellVarName='課程'),wsNew) wbNew.save(filename='test.xlsx')
