Hello, you can wear df.drop_duplicates() to filter the fields. Pandas import is implicit and dataframe creation I will also use your example that is so:
df_sem_duplicacao = df.drop_duplicates(subset=['B'])
df_sem_duplicacao
The parameter subset receives a list with column labels. By default, df.drop_duplicates(), removing only those that are exactly equal. But that’s not what we want, so I use the parameter subset to specify where I want to apply the filter.

df = df.drop_duplicates(subset=['B'])
