How can I limit to 5 digits a Python variable (float type)?

Question

I have the variable

current_price = 1.158805

But I need to limit to 5 numbers (in this case I want the current price to be 1.15880), what can I do?

I need a general solution because the variable changes every second.

And what if I have the numer in a pandas dataframe, for example data.close.iloc[-1]?

What if the number is `current_price = 1.1588050`? Or what if you have `0.5`? — mkrieger1, Nov 09 '21 at 09:27
@mkrieger1 I think it cannot assume 7 digits, but in case that would be fine too for what i need to do. If 0.5 that would be a problem... any idea how to solve? — Trees Jin, Nov 09 '21 at 09:31
What would be fine? What should be the result in these two example? — mkrieger1, Nov 09 '21 at 09:31
So you don't need to remove the "last" digit, but you need to limit the number to 5 digits? — mkrieger1, Nov 09 '21 at 09:40
@mkrieger1 Yes exactly, maybe i have to modify my question? (sorry i am new here) — Trees Jin, Nov 09 '21 at 09:44

 current_price = 1.158805
 
 print(str(current_price)[:-1])

Your output will be:

 >>> 1.15880
