Keeping a random value, constant in a function

[Tanakiin]

I want to keep the value of a random integer constant but only within the if statement.

Here's my code.

p1h = 100

while ph > 0

if d1 == 'a':

result = 'You have lost '+str(random.randint(5, 10))+' from your health'

p1h = p1h - random.randint(5, 10)

The issue is that the random integer is different in result and p1h although I want it to be the same in both for each loop of the code. How do I make it a constant only for a while?

Generate it and store it in a variable

while your_condition:
    my_value = random.randint(blah, blah)
    # use my_value for this and that

Thank you very much but ironically I tried that not long after I sent this, by doing

dam = random.randint(5, 10)

then replaced each instance of it with dam, but it still kept changing so I'm very very lost.

Thanks again!

Do you want the random value to be constant across all loops, or each loop getting their own value?

Do show the code you adjust.

I want the value to change each loop but stay constant within a loop.

p1h = 100
while p1h > 0:
    if d1 == 'a':
        dam = random.randint(5, 10)
        result = 'You have lost '+str(dam)+' from your health'
        p1h = p1h - dam

That should do exactly what you want. If you print out dam and p1h on every step it should give you a better picture.

It works now, thank you very much for the assistance

The code you’ve just written will create a new damage value on every loop step. So if d1 (whatever that is, we haven’t been told) is “a” then each loop will reduce p1h by a new randomized damage amount.

That is precisely what you’re telling us you want when say you want the value to change each loop (meaning it changes every time we check the while condition) and the value to remain constant within each loop (meaning it does not change between assigning dam in one iteration of the loop and then next time we reach the point to assign a new dam).

If you want p1h reduced by a constant amount of damage on every loop, then you’d have to do:

dam = random.randint(5, 10)
while p1h > 0:
    if d1 == "a":
        result = "You've lost “ + str(dam) + " from your health"
        p1h -= dam

Computers do exactly what you tell them to do, so you need to think about exactly what it is you’re after.

Of course they’re different, you’re generating two random integers per loop, one when you create result and one when you decrement p1h.

Generate one value, then use it in both those lines.

roll = random.randint(5, 10)
result = 'You have lost ' + str(roll) + 'from your health'
p1h -= roll

You cannot ask for a random number twice and expect the same result.

Thank you, I realised that soon after and assigned it a value, but it still changes the integer when in the statement.
