Description:

Review current backend code and see where we can optimise it using lambda expressions. For example replace this

users_list = UserModel.query.filter(UserModel.id != user_id).all()
list_of_users = []
for user in users_list:
    if user.is_email_verified:
    list_of_users += [user.json()]
]

with something like this:

users_list = UserModel.query.filter(UserModel.id != user_id).all()
list_of_users = filter(lambda user: user.is_email_verified, users_list)
