You are forgetting to commit to the database!
您忘记提交到数据库！
import psycopg2
try:
conn = psycopg2.connect(database = "projetofinal", user = "postgres", password = "admin", host = "localhost", port = "5432")
except:
print("I am unable to connect to the database")
cur = conn.cursor()
try:
cur.execute("CREATE TABLE test (id serial PRIMARY KEY, num integer, data varchar);")
except:
print("I can't drop our test database!")
conn.commit() # <--- makes sure the change is shown in the database
conn.close()
cur.close()
