Write and demonstrate a Lambda function named stg() that appends .txt to its argument. What happens when you call the function with an integer?

Question

What will be an ideal response?

Answer 1

>>> stg = lambda b: b + '.txt'
>>> stg('aaa')
'aaa.txt'

When called with an integer, the function returns an error when it tries to
catenate an integer and a string:

TypeError: unsupported operand type(s) for +: 'int' and 'str'
