[ojbkaaaa]

1、
a = "[*].8a1c7c33-68cd-49d7-b9a6-1d3833a65ab5"
parse(a)
retuen Exception: Parse error at 1:4 near token 8 (NUMBER)

2、
a = '[*].{}'.format("eb71bcac-ccad-4a05-aeb6-7b092398429c")
parse(a)
retuen Child(Slice(start=None,end=None,step=None), Fields('eb71bcac-ccad-4a05-aeb6-7b09
2398429c'))

Why are different results?
One returns correctly, one gives an error
