Q 3 = Write a python program that calculates and prints the number of seconds in a year .

Answer = 

print ( "for non leap year = " ,60*60*24*365, " , for leap year = ", 60*60*24*366 )

Q 4 =  Write a python program that accepts two integers from the user and print a message saying if first number is divisible by second number or if it is not .

Answer =

first = int(input("enter the first number "))
second = int(input("enter the second number "))

if first % second == 0 :
    print ("first number is divisible by second number ")

else :
    print ("first number is not divisible by second number ")

Q 5 = write a program that ask the user the day number in the year in the range 2 to 365 and ask the first day of the year Sunday or Monday or Tuesday e.t.c . then the program should display the day on the day number that has been input .

Answer =

d = {"Sunday":1,"Monday":2,"Tuesday":3,"Wednesday":4,"Thursday":5,"Friday":6,"Saturday":7}

days = { 1 :"Sunday",2:"Monday",3:"Tuesday",4:"Wednesday",5:"Thursday",6:"Friday",7:"Saturday"}

dic= { }

user = int(input("Enter a number between 2 to 365 = "))

day = input("Enter first day of year (Sunday, Monday, Tuesday,Wednesday,Thursday,Friday,Saturday)")

first = d[day]
print(first)

for j in range(1,366) :
        dic[ j ] = first
        if first == 7 :
            first = 0
        first += 1

a = dic[ user ]

print(days [ a ])

Q 6 = one foot equals 12 inches . write a function that accept a length written in feet as an argument  and returns this length written in inches . write a second function that ask the user for a number of feet and return this value . write a third function that accept a number of inches and display this to the screen . use these three functions to write a program that asks the user for a number of feet and tells them the corresponding number of inches .

Answer:-

def inch(feet):  						#1
	return feet*12
	
def ask():							#2
	ft=int(input("enter number in feet "))
	return ft 
	
def inch2(inch):
	print(inch)
	
inch2(inch(ask()))	

    

Q7 = Write a program that reads an integer N from the keyboards computes and displays the sum of numbers from N to (2*N) if N is nonnegative. If N is a negative number , then it’s the sum of the numbers from (2*N) to N . the starting and ending points are included in the sum .

Answer:-

sum = 0

n = int(input("enter the number "))

if n > 0 :
    for i in range (n,n*2+1):
        sum += i
else :
    for i in range (2*n, n+1):
        sum += i
        
print (sum)

Q 8 = Write a program that reads a date as an integers in the format MMDDYYYY  . the program will call a function that prints print out the date in the format <month name > <day>,<year> .

Answer:-

mon = ["january", "february","march" , "april", "may" , "june" , "july" , "august ", "september ", "october ", "november" , 'december ']

a = int (input("enter the date  = " ))

month = a // 1000000
date = (a % 1000000) // 10000
year = a % 10000

print ( mon [ month - 1 ] , date ," , ", year )

Q 9 = Write a program that prints a table on two columns – table that helps converting miles into kilometers .

Answer:-

    print( 1.6093  * 10** j )

Q 10 = Write another program printing a table with two columns that  helps convert pounds in kilograms .

Answer:-
