Inconsistent print formatting using .format() in Jupiter notebook

I use this return statement twice in my class definition, in two different methods. When the methods run they print differently. One creates a new line at the '\n' and the other prints out the '\n' like a string. I copied the code into an online IDE and got the correct result from that.

In:
`def __str__(self):
return '{0:<16}{1:>20}\n{2:<16}{3:>20}'.format('Account Owner:', self.owner, 'Account Balance:', self.balance)`

Out1:
Account Owner: Jose
Account Balance: 100

Out2:
'Withdrawal Amount: Jose\nNew Account Balance: 75'

No repository file, test, or entry point is identified. Start by reproducing the two class methods in Jupyter Notebook and compare how their returned strings are displayed; done means determining whether the discrepancy is notebook rendering behavior or an issue in the reported formatting path.
