如何通过python取决于maya中的父对象

Question

我对Python有点新手，我正在尝试使用maya中的父对象，具体取决于他们的名字。示例我在场景中有“spineA_jnt”，“spineB_jnt”，“spineC_jnt”和“spineA_jb”，“spineB_jb”，“spineC_jb”。如何选择它们并将父“spineA_jnt”添加到“spineA_jb”等等。任何提示都会非常感谢，谢谢。

您可以使用字典：

spines = "spineA_jnt", "spineB_jnt", "spineC_jnt", "spineA_jb", "spineB_jb", "spineC_jb"
def group_spines(spines):
    spine_dict = {}
    for spine in spines:
        parts = spine.split('_')
        if parts[0] in spine_dict:
            spine_dict[parts[0]].append(spine)
        else:
            spine_dict[parts[0]]=[spine]
    return spine_dict

spine_dict = group_spines(spines)
# results of group_spines function
{'spineA': ['spineA_jnt', 'spineA_jb'],
 'spineB': ['spineB_jnt', 'spineB_jb'],
 'spineC': ['spineC_jnt', 'spineC_jb']}

final_result = dict(spine_dict.values())
# now we have parented the spine parts together 
{'spineA_jnt': 'spineA_jb',
 'spineB_jnt': 'spineB_jb',
 'spineC_jnt': 'spineC_jb'}
