Sum of three user input numbers

int() to get Integer from String

a=int(input("Enter first Number"))
b=int(input("Enter second Number"))
c=int(input("Enter third Number"))
sum=a+b+c
print(sum)

Enter mark to get status of your division

 m=int(input("Enter your marks"))
if(m>=90):
    print("You have Passed with First Distinction")

else:
    if(m>=60):
        print("You have passed with Second Distinction")
    else:
        if(m>=35):
            print("You have just passed work hard next time")
        else:
            print("Failed")

In place of using multiple if else , it is better to use elif.

Converting Decimal to Binary number

def my_binary(n):
    i=''
    while n>1:
        a = n%2
        n = n//2
        i=str(a)+i
    i=  str(n%2) +i   
    print (i)
    
a=my_binary(156)

round a number without using round() function

x=float(input("input number "))
y=int(x+0.5)
print(y)

FCP (First Contentful Paint): The time it takes for the first piece of content to appear on the screen.
LCP (Largest Contentful Paint): Measures the loading performance of the largest content element visible in the viewport.
CLS (Cumulative Layout Shift): Evaluates the visual stability by measuring unexpected layout shifts during the page load.
INP (Interaction to Next Paint): Measures the responsiveness by evaluating the time from user interaction to the next frame painted.
