[FIXED] How to keep trailing 0s when round a number in python?

Issue

I wanted to keep two decimal places after the decimal and keep the trailing 0s for example. 17.7 I want it to be 17.70, or 22.00. So, I have a list of numbers I want to return the maximum and round so that it fits that format.

list = [11, 12.3, 14, 200.33, 49.08, 207.2]

a = max(round(list), 2)

This is what I have done, but it still does not round all the points separately and keep the 2 decimal places. I am not tied to keeping round inside of max, I was just experimenting.

Solution

Short answer, you can't. Unless you modify the underlying object, you cannot change its representation. What you might want is a string formatted to look like this. Here are two approaches:

my_list = [11, 12.3, 14, 200.33, 49.08, 207.2]
['%.2f'%i for i in my_list]

output:

['11.00', '12.30', '14.00', '200.33', '49.08', '207.20']

f-strings (python >3.6):

[f'{i:.2f}' for i in my_list]

NB. do NOT call a list "list", this is already a python builtin
