Post.author is most likely a User model (check your models.py to confirm) therefore should be compared with an equivalent User model which is request.user and not request.user.username:

if request.user == Post.author :
        deletepost.delete()

It is best if you compare the User instance instead of usernames in the case of users changing usernames and/or having duplicate usernames.

you need to compare request.user.username with Post's object which is deletepost.

if request.user.username == deletepost.author.username :
    deletepost.delete()
