Python Newline \n not working in jupyter notebooks

I'm trying to display the tuples of a postgreSQL table neatly in my Jupyter Notebook, but the newline \n escape character doesn't seem to work here (it works for my python scripts w/ same code outside of jupyter).

I'm trying to run:

cur.execute('SELECT * FROM Cars')
'\n '.join(str(x) for x in cur.fetchall())

But my output still contains the '\n' characters themselves:

"(1, 'Toyota', 'Supra', 2020, 'Sport', 'Gas', 49995.0, 7, 280.0, datetime.date(2020, 5, 27), 'Loan', 50150.0, 300.0, 987654321, 333356789)\n (4, 'Chevrolet', 'Corvette', 2020, 'Sport', 'Gas', 55999.0, 4, 280.0, datetime.date(2020, 5, 27), 'Loan', 58999.0, 300.0, 987444321, 333356789)\n (2, 'Toyota', '4Runner', 2018, 'Sport', 'Gas', 40599.0, 13266, 280.0, datetime.date(2020, 5, 27), 'Loan', 58999.0, 300.0, 987334321, 333356789)"

Any ideas as to what I need to do or add?

For me, I was exporting my .ipynb file to .pdf, And because I was printing all my knowledge in one print line, it was cropped out in the PDF version.

The easiest solution is to use the Triple Quotes.

# instead of
print("You're Strong, But I Could Snap My Fingers And\nYou'd All Cease To Exist.")

# use
print("""
You're Strong, But I Could Snap My Fingers And 
You'd All Cease To Exist.
"""

[Output]
Youre Strong, But I Could Snap My Fingers And
You'd All Cease To Exist.

When you don't put the output in print statement. "\n" would be printed as "\n" instead of newline in jupyter notebook and python shell.

in: 'A\nB'

out: 'A\nB'

in: print('A\nB')

out:

A
B

The solution you need is: print('\n '.join(str(x) for x in cur.fetchall()))
