In anticipation of the growing need for antipodeans to write lines of text from bottom to top, I have provided the following python3 program to convert existing text files to this format...

#!/usr/bin/env python3
# bot2top.py
import sys
if int(sys.version[0]) < 3:
    sys.exit("Please use python3")
while True:
    filename = input("Enter filename with lines of text to be reversed: ")
    try:
        f = open(filename, "r")
        break
    except:
        print("File not found. Please re-enter filename...")
        continue
for line in reversed(f.readlines()):
    print(line[:-1])
f.close()

...and for those of you who have difficulty reading python programs written from top to bottom, then here it is again, but written from bottom to top...

f.close()
    print(line[:-1])
for line in reversed(f.readlines()):
        continue
        print("File not found. Please re-enter filename...")
    except:
        break
        f = open(filename, "r")
    try:
    filename = input("Enter filename with lines of text to be reversed: ")
while True:
    sys.exit("Please use python3")
if int(sys.version[0]) < 3:
import sys
# bot2top.py
#!/usr/bin/env python3
