Here we use min function to find minimum number in the list. python # your code goes here numbers =[1,5,3,9,2] smallest_number =min(numbers) print(smallest_number) Output: 1 In this example, we have a list of integers called "numbers." We use the "min" function to find the sma...
for num in data: # Check if the current number 'num' is greater than the current maximum 'l'. if num > l: l = num # If 'num' is greater, update 'l' with 'num'. # Check if the current number 'num' is smaller than the current minimum 's'. elif num < s: s = num # I...
The range() Function in Python The range() function is used to generate a sequence of numbers in python. In the simplest case, the range() function takes a positive number N as an input argument and returns a sequence of numbers containing numbers from 0 to N-1. You can observe this ...

Python - min() functionmin() is an in-built function in Python, which may take N number of arguments and returns minimum value of its arguments. For example, if we provide 3 arguments with the values 20, 10 and 30. min() will return 10 as it is the minimum value among these 3 ...
