# Find the largest number in a list

#### Method 1: Using Loop (Manual method)

```python
def find_largest(nums):
    largest = nums[0]
    for n in nums:
        if n > largest:
            largest = n
    return largest

print(find_largest([10, 45, 2, 67, 89, 23]))
```

**Output:** `89`

## Explanation:

1. Start with the first element as the largest.
2. Compare with each element and update if bigger.
3. The max is `15`.

#### Method 2: Using `max()` (Simplest way)

```python
numbers = [10, 45, 2, 67, 89, 23]

largest = max(numbers)
print("Largest number is:", largest)
```

## Output:

```plaintext
Largest number is: 89
```

#### Method 3: Using Sorting

```python
numbers = [10, 45, 2, 67, 89, 23]

largest = sorted(numbers)[-1]
print("Largest number is:", largest)
```
