Post labs are to be done individually. Sharing files between students is not allowed. Doing so is an Academic Integrity violation, and will be treated as such.
Using file I/O we can create programs with simple databases. Databases created by people often have mistakes in them. Before user-created databases can be used by a program, all erroneous data must be removed. In this activity you will demonstrate your knowledge of file I/O by stripping invalid data form a file.
Write a function called file_strip(input_file_name,
output_file_name). The
parameters input_file_name
and output_file_name are both strings that represent
text files. The function should read the contents
of input_file_name and write a new text file
called output_file_name that is the same as the input
file but with all lines that don't represent integers removed.
Consider any line that consists of entirely digit characters as a
line that represents an integer.
Make sure your program handles all necessary cases gracefully. What additional test cases should you check?
