The thing is that the key of a dictionary needs to be a non-mutable type,
which can be reliably hashed and not change after it becomes a key. A
dictionary cannot be a key to another dictionary because its content can
change. So if you want to be able to map your time-based results within a
selected path, then you have to use some other key. I just chose the time
as each key since its the variable that is different between each loop.
You can try changing your function to something like this:
def export_keyframe(sel):
...
all_data[sel] = {} # init empty time results
for time in range(start_frame , (end_frame + 1)):
attr_data = {}
cmds.currentTime(time)
# Get the value in each attribute
attr_data['frame'] = str(time)
for attribute in attributes:
attr_value = cmds.getAttr( sel + '.' + attribute)
# Assign the value into the dict
attr_data[attribute] = str(attr_value)
# Store the data into the main
all_data[sel][time] = attr_data # assign using time key
...
