如何将文件移动到TopParent文件夹？

Question

我的代码遇到问题。这只是部分工作。

我的目标是在字典中将键（我的文件）与值（顶级父级）相关联。

因此，对于FILE 2,3,4＆5，我想将值“ FILE2”关联 但是现在，键“ FILE5”的值为“ FILE4”，而不是“ FILE2”。

{'FILE': 'FILE', 'FILE2': 'FILE2', 'FILE8': 'FILE8', 'FILE9': 'FILE9', 'FILE2': 'FILE12', 'FILE3': 'FILE2', 'FILE10': 'FILE9', 'FILE13': 'FILE12', 'FILE4': 'FILE2', 'FILE1': 'FILE9', 'FILE5': 'FILE4'}

我认为我缺少递归功能。但我不知道如何解决。

def FunctionD(item, dico):
    '''Create a dictionary where UltimateParent is key and value'''
    dico[item] = item


def FunctionE(child, parent, dico,dico2):
    '''Create a dictionary to assign the UltimateParent to some Children. If parent is key, we assign the parent as a value.'''
    '''/!\Here is the problem I think'''
    if parent in dico2 :
        dico[child] = parent
    if parent in dico2.values():
        dico[child] = dico[parent]



def FunctionA(path_src, path_dest, path_excel) :
    ''' Main fonction'''

    flag = input('Do you want the files sort by UltimateParent, by Reviewer or by Responsiveness ? (any key/Rw/Rp)')

    '''Read the Excel sheet and store it into a dataframe'''
    excel_file =path_excel
    df = pd.read_excel(excel_file)
    A = df.iloc[:,0].tolist() #ColumnA
    B = df.iloc[:,1].tolist() #ColumnB

    '''Try of assign the correct Ultimate Parent for each File'''
    dico ={}
    [FunctionD(i,dico) for i,j in zip(A,B) if isinstance(j, float)] #Dic Parents
    dico2 = dico.copy()
    [FunctionE(i, j, dico,dico2) for i, j in zip(A, B) if not isinstance(j, float)] #Associe parents et enfants (sf petitsenfants)
    dico3 =dico.copy()
    [FunctionE(i, j, dico, dico3) for i, j in zip(A, B) if not isinstance(j, float)] # Associe enfant aux parents
    dico4 = dico.copy()
    [FunctionE(i, j, dico, dico4) for i, j in zip(A, B) if not isinstance(j, float)]

    '''Creation of the UltimateParent folder'''
    [FunctionB(path_dest, i) for i,j in zip(A,B) if isinstance(j, float)] #creation des dossiers des parents
