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

Yes

The word "pratica" (the third-person singular conjugation of the verb praticar) is identical in both Brazilian and Continental Portuguese in terms of meaning, spelling, and grammatical function. The differences are limited to:

• Pronunciation: In Continental Portuguese, unstressed vowels are much more reduced (a phenomenon called vowel reduction). The final "a" in "pratica" is often nearly silent or pronounced as a very short, neutral "schwa" sound. In Brazilian Portuguese, the "a" is more open and clearly articulated.
• Collocation (Contextual Usage): While the word itself remains the same, the nouns that typically follow it change because of regional vocabulary. For example, a Brazilian will use "praticar esportes," while a Portuguese person will naturally use "praticar desportos."
