# Python Program to Find Largest/Maximum of n Numbers

## The objective of this Python post, you will see various Python programs that cover the following:

• Python program to find largest of n numbers using max
• Python program to find largest of n numbers without using built-in function

### Python program to find largest of n numbers using max

• Take input number for the length of the list using python input() function.
• Initialize an empty list `lst = []`.
• Read each number in your python program using a `for loop`.
• In the for loop append each number to the list.
• Use built-in python function `max()` to find the largest element in a list.
• End of the program print the largest number from list.
```lst = []

num = int(input('How many numbers: '))

for n in range(num):
numbers = int(input('Enter number '))
lst.append(numbers)

print("Maximum element in the list is :", max(lst))
```

Output

```How many numbers:  5
Enter number  4
Enter number  6
Enter number  8
Enter number  9
Enter number  10
Maximum element in the list is : 10
```

### Python program to find largest of n numbers without using built-in function

• Take input number for the length of the list using python input() function.
• Initialize an empty list `lst = []`.
• Read each number in your python program using a `for loop`.
• In the for loop append each number to the list.
• Define a custom function, which is an accepted number list and used to find the largest number from list.
• Call this custom function and store the function result.
• End of the program print the largest number from list.
```def find_max( list ):
max = list[ 0 ]
for a in list:
if a > max:
max = a
return max

num = int(input('How many numbers: '))

lst = []

for n in range(num):
numbers = int(input('Enter number '))
lst.append(numbers)

print("Maximum element in the list is :", find_max(lst))
```

Output

```How many numbers:  3
Enter number  1
Enter number  5
Enter number  7
Maximum element in the list is : 7
```
