for step in instructions:
if step == 'f': y += 1
elif step == 'b': y -= 1
elif step == 'r': x += 1
elif step == 'l': x -= 1
return (x, y)

print(follow("fflff"))
# These "asserts" are used for self-checking and not for an auto-testing
assert follow("fflff") == (-1, 4)
assert follow("ffrff") == (1, 4)
assert follow("fblr") == (0, 0)
