In the Muggles Guide to Harry Potter it says that one of the Patil twins is in Gryffindor and the other is in Ravenclaw.
But then in the Goblet of Fire movie, they are both in the Gryffindor common room.
So are they both in Gryffindor or what?
This appears to be a mistake/change in the films as referenced in this wikia page on the twins.
Padma Patil: While depicted as a Gryffindor in the movies, she is sorted as a Ravenclaw in the books.
This is backed up by a this answer by @Kevin to a related question and the following quote.
Brothers and sisters usually go in the same Houses, don’t they?” [Harry] said. He was judging by the Weasleys, all seven of whom had been put into Gryffindor.
“Oh no, not necessarily,” said Hermione. “Parvati Patil’s twin’s in Ravenclaw, and they’re identical. You’d think they’d be together, wouldn’t you?”
— Goblet of Fire, chapter 12 (The Triwizard Tournament)
The Pottermore articles on the two also show the following.
Padma is Ravenclaw in the books but Gryffindor in the movies.
The reason that Padma is in the Gryffindor common room in the movies is because in the movies, she is a Gryffindor. Both Patil twins are Gryffindor in the movies - we can see that from their Gryffindor ties.
This isn’t just a one-time error either. They’re consistently both shown as being Gryffindors throughout the movies. They both are consistently wearing the red-collared Gryffindor robes with the house crest on them and the ties whenever they are seen in uniform.
In the books, however, Padma is a Ravenclaw and Parvati is a Gryffindor.
“Well …’ said Parvati slowly, ‘I suppose my sister might … Padma, you know … in Ravenclaw. I’ll ask her if you like.”
- Harry Potter and the Goblet of Fire, Chapter 22 (The Unexpected Task)
So, The Muggles’ Guide to Harry Potter is right for the books, but in the movies, Padma is consistently a Gryffindor.
