Given a list of numbers, the task is to write a Python program to find the smallest number in given list.
Examples: 

Input : list1 = [10, 20, 4]
Output : 4

Input : list2 = [20, 10, 20, 1, 100]
Output : 1

Method 1 : Sort the list in ascending order and print the first element in the list.  

Python3




# Python program to find smallest
# number in a list
 
# list of numbers
list1 = [10, 20, 4, 45, 99]
 
# sorting the list
list1.sort()
 
# printing the first element
print("Smallest element is:", *list1[:1])


Output: 

smallest element is: 4

Method 2 : Using min() method  

Python3




# Python program to find smallest
# number in a list
 
# list of numbers
list1 = [10, 20, 1, 45, 99]
 
 
# printing the maximum element
print("Smallest element is:", min(list1))


Output: 

Smallest element is: 1

Method 3 : Find min list element on inputs provided by user. 

Python3




# Python program to find smallest
# number in a list
 
# creating empty list
list1 = []
 
# asking number of elements to put in list
num = int(input("Enter number of elements in list: "))
 
# iterating till num to append elements in list
for i in range(1, num + 1):
    ele= int(input("Enter elements: "))
    list1.append(ele)
     
# print maximum element
print("Smallest element is:", min(list1))


Output: 

Enter number of elements in list: 4
Enter elements: 12
Enter elements: 19
Enter elements: 11
Enter elements: 99
Smallest element is: 11

Method 4: Find the smallest element in list.  

Python3




# Python program to find smallest
# number in a list
 
l=[ int(l) for l in input("List:").split(",")]
print("The list is ",l)
 
# Assign first element as a minimum.
min1 = l[0]
 
for i in range(len(l)):
 
    # If the other element is min than first element
    if l[i] < min1:
        min1 = l[i] #It will change
 
print("The smallest element in the list is ",min1)


Input: 

List: 23,-1,45,22.6,78,100,-5

Output: 

The list is ['23', '-1', '45', '22.6', '78', '100','-5']
The smallest element in the list is  -5
