Selection Sort Solution to Exercise and True output does not match

[MadhavWagh]

The last 4 sorted elements from solution are:
{'First Name': 'Raj', 'Last Name': 'Sharma'}
{'First Name': 'Raj', 'Last Name': 'Nayyar'}
{'First Name': 'Raj', 'Last Name': 'Thakur'}
{'First Name': 'Suraj', 'Last Name': 'Sharma'

but alphabetically, 'Nayyar' should come before 'Sharma'.

The attached code below gives the desired o/p.
