Harry Potter the character does not have dyspraxia, the actor
who played him Daniel Radcliffe does.
Radcliffe has not discussed his dyspraxia much in public, but he
did mention that he struggles with simple tasks such as tying his
shoelaces. His publicist stated that Radcliffe only has mild
dyspraxia.
Not a lot is known about dyspraxia and those with it tend to
find ways to adapt to the tasks they find difficult.
