Understanding inplace=True in pandas

by

When inplace=True is passed, the data is renamed in place (it returns nothing), so you’d use:

df.an_operation(inplace=True)

When inplace=False is passed (this is the default value, so isn’t necessary), performs the operation and returns a copy of the object, so you’d use:

df = df.an_operation(inplace=False)
