TypeError: list indices must be integers or slices, not float

[RedSkeleton007]

Why can't I just get two decimal places to the right of the decimal point?
Or are the circumstances with list indexes different:

#!/usr/bin/env python3
#SamsLists.py

myInts = [1,8,4,7,6]
for i in myInts:
    print(i)

moneyFloats = [2.1, 6.2, 7.8, 9.1, 5.4]
for i in moneyFloats:
    print("{:,.2f}".format(moneyFloats[i]))

Error:
Traceback (most recent call last):
  File "I:/Python/Python36-32/SamsPrograms/SamsLists.py", line 10, in <module>
    print("{:,.2f}".format(moneyFloats[i], 2))
TypeError: list indices must be integers or slices, not float

moneyFloats contains floats.
Just remove the index part in format method.

moneyFloats = [2.1, 6.2, 7.8, 9.1, 5.4]
for num in moneyFloats:
    print("{:,.2f}".format(num))
