Python Program to Find the Smallest Number in a List

This is a Python Program to find the Smallest number in a list.

Problem Description

The program takes a list and prints the smallest number in the list.

Problem Solution

1. Take in the number of elements and store it in a variable.
2. Take in the elements of the list one by one.
3. Sort the list in ascending order.
4. Print the last element of the list.
5. Exit.

Source Code

li = [] 
n = int(input("Enter the number of elements: "))
for i in range(1, n+1): 
    elem = int(input("Enter the elements: ")) 
    li.append(elem) 
li.sort() 

print("The sorted list: ", li) 
print("The smallest value of this list: ",li[0]) 

Program Explanation

1. User must enter the number of elements and store it in a variable.
2. User must then enter the elements of the list one by one using a for loop and store it in a list.
3. The list should then be sorted.
4. Then the first element of the list is printed which is also the smallest element of the list.

Test Case-1

li = [] 
n = int(input("Enter the number of elements: "))
for i in range(1, n+1): 
    elem = int(input("Enter the elements: ")) 
    li.append(elem) 
li.sort() 

print("The sorted list: ", li) 
print("The smallest value of this list: ",li[0])

Enter the number of elements: 4
Enter the elements: 36
Enter the elements: 14
Enter the elements: 52
Enter the elements: 78
The sorted list:  [14, 36, 52, 78]
The smallest value of this list:  14

Test Case-2

li = [] 
n = int(input("Enter the number of elements: "))
for i in range(1, n+1): 
    elem = int(input("Enter the elements: ")) 
    li.append(elem) 
li.sort() 

print("The sorted list: ", li) 
print("The smallest value of this list: ",li[0])

Enter the number of elements: 10
Enter the elements: -7
Enter the elements: 15
Enter the elements: 86
Enter the elements: -3
Enter the elements: 0
Enter the elements: 49
Enter the elements: 78
Enter the elements: 2
Enter the elements: -3
Enter the elements: 33
The sorted list:  [-7, -3, -3, 0, 2, 15, 33, 49, 78, 86]
The smallest value of this list:  -7

Test Case-3

li = [] 
n = int(input("Enter the number of elements: "))
for i in range(1, n+1): 
    elem = int(input("Enter the elements: ")) 
    li.append(elem) 
li.sort() 

print("The sorted list: ", li) 
print("The smallest value of this list: ",li[0])

Enter the number of elements: 5
Enter the elements: -4
Enter the elements: -3
Enter the elements: -2
Enter the elements: -1
Enter the elements: 0
The sorted list:  [-4, -3, -2, -1, 0]
The smallest value of this list:  -4
