5 Best Ways to Round Float to 2 Decimals in Python – Be on the Right Side of Change
In the code above, the placeholder {:.2f} within the string defines the format, indicating that the float should be formatted with two decimal places. The format method then replaces the placeholder with the rounded number. The Decimal module in Python provides arithmetic with as much precision as needed.

"%.2f" does not return a clean float. It returns a string representing this float with two decimals.
my_list = [0.30000000000000004, 0.5, 0.20000000000000001]
my_formatted_list = [ '%.2f' % elem for elem in my_list ]
returns:
['0.30', '0.50', '0.20']
Also, don't call your variable list. This is a reserved word for list creation. Use some other name, for example my_list.
If you want to obtain [0.30, 0.5, 0.20] (or at least the floats that are the closest possible), you can try this:
my_rounded_list = [ round(elem, 2) for elem in my_list ]
returns:
[0.29999999999999999, 0.5, 0.20000000000000001]

If you really want an iterator-free solution, you can use numpy and its array round function.
import numpy as np
myList = list(np.around(np.array(myList),2))
# OR
myList = np.around(myList,2).tolist()
