Question

所以我想要做的是从字典中写入现有的excel文件：

wb = load_workbook(filename='test.xlsx')
ws2 = wb.get_sheet_by_name("Blad3")
tuple(ws2.iter_rows('A2:I1000'))
for i in ws2.iter_rows('A2:I1000'):
    print str(row[0].value)
    for i in Candidates:
        row[0].value = i['Start Location']
        row[1].value = i['Distance']
        row[2].value = i['End Location']
    for p in Potential_candidates:
        row[4].value = p['Start Location']
        row[5].value = p['Distance']
        row[6].value = p['End Location']
    for n in No_coords:
        row[8].value = No_coords
print 'Saving to file "test.xlsx"'
wb.save('test.xlsx')

“print str（row [0] .value）”从工作表中获取正确的值，但是当我尝试设置它所说的值时： TypeError：'NoneType'对象没有属性' getitem '。

错误发生在第[0]行.value = i ['开始位置']

我一直想弄清楚为什么，或者我错过了最明显的事情，或者我完全迷失了。如果你，你不能写入单元格可以从中读取吗？

所以我想出了NoneType错误的错误，显然列表在[0]处有一个None元素。所以我添加了一个函数来从所有列表中删除这些元素，现在我有一个新的错误：

TypeError：'tuple'对象不支持项目分配

所以我想出了我做错了什么，这很多，首先，我的代码试图用整个字典而不是第一个元素填充每一行。其次row [0] =因为......原因而无效。所以我做了一个凌乱的解决方案（但是有效）：

def write_excel():
wb = load_workbook(filename='test.xlsx')
ws = wb.get_sheet_by_name("Blad3")
count = 0
for row in ws.iter_rows('A2:I500'):
    x = str(row[0].coordinate)
    x1 = str(row[1].coordinate)
    x2 = str(row[2].coordinate)
    x3 = str(row[4].coordinate)
    x4 = str(row[5].coordinate)
    x5 = str(row[6].coordinate)
    x6 = str(row[8].coordinate)
    try:
        Start = Candidates[count]['Start Location']
        Dist = Candidates[count]['Distance']
        End = Candidates[count]['End Location']
        ws[x] = Start
        ws[x1] = Dist
        ws[x2] = End
    except IndexError:   
        pass
    try:
        Pstart = Potential_candidates[count]['Start Location']
        Pdist = Potential_candidates[count]['Distance']
        Pend = Potential_candidates[count]['End Location']
        ws[x3] = Pstart
        ws[x4] = Pdist
        ws[x5] = Pend
    except IndexError:
        pass
    try:
        NoCoo = No_coords[count]
        ws[x6] = NoCoo
    except IndexError:
        pass
    count=count+1
print 'Saving to file "test.xlsx"'
wb.save('test.xlsx')

我知道它可以清理很多，但它帮助我理解了什么是poopoo所以希望它可以帮助其他人:) 当我为整个程序创建更好的代码结构时，我会被清理干净。
