Question:
Write a python program that will take an input file as an environmental variable, copy it to a list, and show every alternative lines in reverse order from the list (i.e. the last line will show first, then the two lines before the last line...and so on.)
You are not allowed to use any loop (such as for, while, etc) for solving this part. You have to use list slicing. You also cannot use any input function. You will have to take files as environmental variable.
Sample Input:
INPUT=inputfile.txt showfileinreverse
Sample Output:
['line8', 'line6', 'line4', 'line2']
Your input file inputfile.txt has the following content:
line1
line2
line3
line4
line5
line6
line7
line8
