It really depends on your type of data, if it's sensitive data or not. And it also depends on what type of backup (Incremental, Decremental, etc.). But you should aim to backup at least once a week, and also do a backup of your original backup.
terms = ["Bandwidth", "Hierarchy", "IPv6", "Software", "Firewall", "Cybersecurity", "Lists", "Program", "Logic",
"Reliability"]
def swap(arr, in1, in2):
w = arr[in1]
arr[in1] = arr[in2]
arr[in2] = w
print(terms)
swap(terms, 5, 1)
swap(terms, 2, 4)
swap(terms, 3, 5)
swap(terms, 5, 6)
swap(terms, 6, 8)
swap(terms, 8, 9)
print(terms)
This is how I interpreted the question. If I need to make any changes, I'll do my best. Hope this helps though.
