Round Function

 '''The round() function in Python is used to round a number to a specified number of decimal places.

round(number, ndigits)'''

number=float(input("Enter a number: "))

ndigits=int(input("Enter the number of decimal places to round to: "))

print(round(number, ndigits))

# The first variable is the number to be rounded, and the second variable is the number of decimal places to round to.


print(round(3.14159, 2))   # Output: 3.14

print(round(5.678, 1))     # Output: 5.7

print(round(4.5))          # Output: 4 (rounds to the nearest even number) 

print(round(5.5))          # Output: 6 (rounds to the nearest even number)


# If ndigits is not specified, the default value is 0, which means rounding to the nearest integer.

print(round(3.14159))      # Output: 3


# If ndigits is negative, it rounds to nearest 10s,100s, etc. as base 10 numbers.

print(round(5.678, -1))    # Output: 10.0

print(round(4.5, -1))      # Output: 0.0

print(round(5432.5, -3))   # Output: 5000.0

    add another few examples of your own.. try different variations, like what happens when you try to round a negative float number

    With Love.

Print Function

#To print something in Python, we write print( ) #print is a function to perform any task. print("Hello World")                                    #output - Hello World #We use double quotes " " to make the object valid and to make it a string. #We can also use single quotes ' ' for the same. print('Hello World')                                      #output = Hello World print(5)                                                         #output - 5 #We didn't use double quote or single quote here as 5 is a number(a valid object) #To print multiple lines in print function, we use triple single or double quotes. print('''Hi How are you?

Sets in Python

''' Python Sets: In Python, a set is an unordered collection of unique elements.  Sets are useful when we need to store a collection of items without any duplicates. Key Characteristics of Sets: 1. Unordered: The items have no defined order, and their position can change. 2. Unique Elements: No duplicate values are allowed. 3. Mutable: Sets can be modified after creation (elements can be added or removed). 4. Heterogeneous: A set can contain elements of different data types. ''' s1 = {1, 2, 3, 4} print(s1)                #output = {1, 2, 3, 4} s2 = {1, 1, 2, 3, 4, 4} print(s2)                #output = {1, 2, 3, 4}   #Duplicates are automatically removed info = {"Sindhu", 24, True, 2002} print(info)              #output = {24, True, 2002, 'Sindhu'}  #Here we can see that the items in set occur in random order, and hence they cannot be accessed using index...
