What to do when the column name is a reserved word of Python

[AzamBukhari]

Hello

During Tips & Tricks lecture we came across a topic of using a function called: unique()

print(df.embark_town.unique())

What to do if we come across a situation where instead of column name 'embark_town' we have to use 'class' for example:
print(df.class.unique())

it is throwing error.,

[Masoodullah909]

df['class'].unique()
