def test(str_nums):
return max(float(s.replace(",", ".")) for s in str_nums)
str_nums = ["100", "102,1", "101.1"]
print("Original list:")
print(str_nums)
print("Largest number where commas or periods are decimal points:")
print(test(str_nums))
```

Sample Output:

Original list: ['100', '102,1', '101.1'] Largest number where commas or periods are decimal points: 102.1
