# Python: Find the largest number where commas or periods are decimal points

## Python Programming Puzzles: Exercise-26 with Solution

Write a Python program to find the largest number where commas or periods are decimal points.

Input: ['100', '102,1', '101.1'] Output: 102.1

**Pictorial Presentation:**

**Sample Solution-1:**

**Python Code:**

```

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

def test(str_nums):
numbers = []
for s in str_nums:
numbers.append(float(s.replace(",", ".")))

**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:

4 -1
