Is the word contentes the same in Brazilian and European Portuguese?

Yes

The word "contentes" is identical in spelling, meaning, and grammar in both Brazilian and Continental Portuguese. The only difference lies in pronunciation.

In Brazilian Portuguese, vowels are typically more "open" and clearly articulated. When a Brazilian says "contentes," each vowel is pronounced distinctly. In Continental Portuguese, there is a significant phenomenon called vowel reduction, where unstressed vowels (like the "e" in the middle of "contentes") are often "closed" or almost completely silenced. Consequently, a Portuguese person might pronounce the word in a way that sounds much closer to "cont'entes" to an untrained ear.
