Given a list of numbers, namely:
write some code to add 42 to every item in this list, producing a new list. For this example data, newlist should contain the values: ( 46, 49, 50 ). Sample answer:
Given a string containing a space-separated list of names:

Given an input text file and an output file as follows:
write some code to read infile and change all occurrences of 'Peking' to 'Beijing', leaving infile unchanged and writing the changed text to a new file outfile. Sample answer:
If they use s/Peking/Beijing/g contrast with s/\bPeking\b/Beijing/g and ask which they prefer.
