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)

Python: Tips of the Day

Clamps num within the inclusive range specified by the boundary values x and y:

Example:

def tips_clamp_num(num,x,y):
  return max(min(num, max(x, y)), min(x, y))
print(tips_clamp_num(2, 4, 6))
print(tips_clamp_num(1, -1, -6))

Output:
