如何在 Python 中将多键 dict 写入 excel？

Question

有没有办法将python中的多键dict写入excel文件，其中键分别是行索引和列标题？这是一个例子：

d={('A', 0): 1.0, ('A', 1): 1.0, ('A', 2): 1.0, ('A', 3):1.0, ('B', 0): 1.0, ('B', 1): 1.0, ('B', 2): 1.0, ('B', 3): 1.0}

我正在寻找如下输出：

我不认为这种字典有什么特殊功能。但是使用 openpyxl 可以实现。字典的键分别包含行标题和列标题。你的字典的价值就是价值。

使用 openpyxl，代码将如下所示（假设您导入了所需的库）：

new_row_no=1 # It will keep info of last row

for key, value in d.items():
    column_no=int(key[1])+2 # Here ('A', 0), 0 is the column no
    row_no=0

    #Update column title here
    sh.cell(row=1, column=column_no, value=key[1])

    # Do some stuff here to decide which row to insert new value
    # Check if row title exists or not
    # If exists, find that row(for example which cell of column A contains 'A' as row title)
    row_no=int(proper_row_no_finder(sh_to_search=sh, value_to_search=key[0]))

    # If row title is new, it means that it is not used, then do extra stuff
    if row_no==0:

        #if not exists, it means that you have to start working with new row
        new_row_no+=1
        row_no=new_row_no
        sh.cell(row=row_no, column=1, value=key[0]) # Add just row title as it is new
        

    # Now you have both row and column number, you can work with that as you wish
    sh.cell(row=row_no, column=column_no, value=value)

wb.save('result.xlsx')

这里是辅助函数：

def proper_row_no_finder(**kwargs):
    sh_to_search=kwargs['sh_to_search']
    value_to_search=kwargs['value_to_search']
    xrow=0
    for col in sh_to_search.iter_cols(min_row=1, max_col=1):
        for xvalue in col:
            if xvalue.value==value_to_search:
                xrow=xvalue.row # Take the row number, you need it to insert new value
            else:
                xrow=0
    return xrow
