Python: Resetting a variable

Question

For the below code, after running start_point = start_point / 10, its value drops to 1,000 and would remain as such if it is called subsequently.

May I know how to reset it to the 10,000 it originally was? I believe one method would be to set a global variable. But is there a simpler way? Like a seek(0)?

def secret_formula(started):
    jelly_beans = started * 500                 
    jars = jelly_beans / 1000                   
    crates = jars / 100                         
    return jelly_beans, crates, jars                

start_point = 10000
item_1, item_2, item_3 = secret_formula(start_point)

print "With a starting point of: %d" % start_point
print "We'd have %d beans, %d jars, and %d crates." % (item_1, item_2, item_3)

start_point = start_point / 10

print "We can also do that this way:"
print "We'd have %d beans, %d jars, and %d crates." % secret_formula(start_point)

Why do you even save the new value, if you're gonna reset it afterwards anyways? Why not just print "We'd have %d beans, %d jars, and %d crates." % secret_formula(start_point / 10) instead? — Raimund Krämer

would creating another variable work?

original_start_point = 1000
start_point = original_start_point

Yes, this should work. This way the OP may always revert to the desired "original value" with start_point = original_start_point provided that they only change the start_point variable and don't work with original_start_point otherwise (it doesn't get modified).
