In this python program, we will find the largest number in a given list. There are various ways to find the largest number in a given list. In this program, we use loops and python built-in functions such as `max()`

, `sort()`

, `reverse()`

.

Here is the source code of the program to find the largest number in a given list.

```
# Python Program to find Largest Number in a List Using a built-in max() function
a = [104, 785, 452, 152, 852, 195]
# Print the List
print("List: ",a)
print("The Largest Element in this List is: ", max(a))
```

List: [104, 785, 452, 152, 852, 195]

The Largest Element in this List is: 852

In this program, we will take the input from the user and find the largest number in a given list using the ** max()** function.

Python Program to Find Largest Number in a Given List Using For Loop and max() Function

```
# Python Program to find Largest Number in a Given List Using For Loop and max() Function
NumList = []
# Take the Input from the Number
Number = int(input("Enter the Total Number of List Elements: "))
for i in range(1, Number + 1):
value = int(input("Enter the Value of %d Element: " %i))
NumList.append(value)
# Print the List Entered By the User
print("List: ",NumList)
print("The Largest Element in this List is: ", max(NumList))
```

Enter the Total Number of List Elements: 6

Enter the Value of 1 Element: 45

Enter the Value of 2 Element: 15

Enter the Value of 3 Element: 65

Enter the Value of 4 Element: 62

Enter the Value of 5 Element: 48

Enter the Value of 6 Element: 35

List: [45, 15, 65, 62, 48, 35]

The Largest Element in this List is: 65

```
# Python Program to find Largest Number in a Given List using the sort() function
lst=[]
# Take the Input from th User
number=int(input("Enter the Total Number of List Elements: "))
for i in range(1,number+1):
b=int(input("Enter the Value of %d Element: "%i))
lst.append(b)
# Print the List Entered By the User
print("List: ", lst)
lst.sort()
print("The Largest Element in this List is: ",lst[number-1])
```

The Largest Element in this List is: 6

Enter the Total Number of List Elements: 5

Enter the Value of 1 Element: 45

Enter the Value of 2 Element: 52

Enter the Value of 3 Element: 36

Enter the Value of 4 Element: 85

Enter the Value of 5 Element: 456

List: [45, 52, 36, 85, 456]

The Largest Element in this List is: 456

In this program, we take the input from the user and find the largest number from the given list by using python built-in

and **sort()**

functions where **reverse()**** sort()** function sort the list in the ascending order and reverse function reverse the sorted list.

```
# Python Program to find Largest Number in a Given List using sort() and reverse() function
NumList = []
Number = int(input("Enter the Total Number of List Elements: "))
for i in range(1, Number + 1):
value = int(input("Enter the Value of %d Element: " %i))
NumList.append(value)
# print the List Entered By the User
print("\nList: ", NumList)
# Sort the List in Ascending Order
NumList.sort()
# Reverse the List
NumList.reverse()
print("The Largest Element in this List is : ", NumList[0])
```

Enter the Total Number of List Elements: 6

Enter the Value of 1 Element: 23

Enter the Value of 2 Element: 52

Enter the Value of 3 Element: 48

Enter the Value of 4 Element: 321

Enter the Value of 5 Element: 526

Enter the Value of 6 Element: 462

List: [23, 52, 48, 321, 526, 462]

The Largest Element in this List is : 526

```
# Python Program to find Largest Number with its Index Position in a Given List Without using any Function
NumList = []
# Take the Input from the User
Number = int(input("Enter the Total Number of List Elements: "))
for i in range(1, Number + 1):
value = int(input("Enter the Value of %d Element: " %i))
NumList.append(value)
# Print the List Entered by the User.
print("\nList: ", NumList)
largest = NumList[0]
for j in range(1, Number):
if(largest < NumList[j]):
largest = NumList[j]
position = j
print("The Largest Element in this List is : ", largest)
print("The Index position of the Largest Element is : ", position)
```

Enter the Total Number of List Elements: 6

Enter the Value of 1 Element: 521

Enter the Value of 2 Element: 652

Enter the Value of 3 Element: 325

Enter the Value of 4 Element: 452

Enter the Value of 5 Element: 854

Enter the Value of 6 Element: 653

List: [521, 652, 325, 452, 854, 653]

The Largest Element in this List is : 854

The Index position of the Largest Element is : 4
