String slicing problem

[Ollew]

Hi, can someone please help me understand why this code doesn't work?

data = 'XBOX 360 | 150 | NEW'

product = data[data.index('1'):data.index('|')]
product
''
product = data[data.index('1'):data.index('N')]
product
'150 | '

As you can see it works when I index 'N' but not the '|'
