Q.1812110027: Find Year
QUESTION DESCRIPTION
Most years have 365 days. However, the time required for the Earth to orbit the Sun is actually slightly more than that. As a result, an extra day, February 29, is included in some years to correct for this difference. Such years are referred to as leap years.

The rules for determining whether or not a year is a leap year follow:

Any year that is divisible by 400 is a leap year.
Of the remaining years, any year that is divisible by 100 is not a leap year.
Of the remaining years, any year that is divisible by 4 is a leap year.
All other years are not leap years.

Write a program that reads a year from the user and displays a message indicating
whether or not it is a leap year.

a=int(input())

if a%400==0:

print(str(a) + " is a leap year")

elif a%100==0:

Q.1812110018: Note To Frequency - G NOTE
QUESTION DESCRIPTION
The following table lists an octave of music notes, beginning with middle G, along with their frequencies.

Note Frequency (Hz)
G4 392.00

Begin by writing a program that reads the name of a note from the user and displays the notes frequency. Your program should support all of the notes listed previously.

Once you have your program working correctly for the notes listed previously you should add support for all of the notes from G0 to G8.

While this could be done by adding many additional cases to your if statement, such a solution is cumbersome,
inelegant and unacceptable for the purposes of this exercise. Instead, you should exploit the relationship between notes in adjacent octaves. In particular, the frequency of any note in octave n is half the frequency of the corresponding note in octave n+1.

By using this relationship, you should be able to add support for the additional notes without adding additional cases to your if statement.

Hint: To complete this exercise you will need to extract individual characters from the two-character note name so that you can work with the letter and the octave number separately.

Once you have separated the parts, compute the frequency of the note in the fourth octave using the data in the table above.

Then divide the frequency by 2 power(4-x ), where x is the octave number entered by the user. This will halve or double the frequency the correct number of times.

Then divide the frequency by 2 power(4-x ), where x is the octave number entered by the user. (freq=freq/2**(4-octave))

C4_FREQ = 261.63

D4_FREQ = 293.66

E4_FREQ = 329.63

F4_FREQ = 349.23

G4_FREQ = 392.00

A4_FREQ = 440.00

B4_FREQ = 493.88

# Read the note name from the user

name = input()

# Store the note and its octave in separate variables

note = name [0]

octave = int(name[1])

# Get the frequency of the note, assuming it is in the fourth octave

if note == "C":

freq = C4_FREQ

elif note == "D":

freq = D4_FREQ

elif note == "E":

freq = E4_FREQ

elif note == "F":

freq = F4_FREQ

elif note == "G":

freq = G4_FREQ

elif note == "A":

freq = A4_FREQ

elif note == "B":

# Now adjust the frequency to bring it into the correct octave

Q.1812110040: Sieve of Eratosthenes
QUESTION DESCRIPTION
Python Program to Read & Print Prime Numbers in a Range using Sieve of Eratosthenes.

To find all the prime numbers less than or equal to a given integer n by Eratosthenes' method:

Create a list of consecutive integers from 2 through n: (2, 3, 4, ..., n).

Initially, let p equal 2, the smallest prime number.

Enumerate the multiples of p by counting to n from 2p in increments of p, and mark them in the list (these will be 2p, 3p, 4p, ...; the p itself should not be marked).

Find the first number greater than p in the list that is not marked. If there was no such number, stop. Otherwise, let p now equal this new number (which is the next prime), and repeat from step 3.

When the algorithm terminates, the numbers remaining not marked in the list are all the primes below n.

Q.1815110007: Does a String Represent an Integer
QUESTION DESCRIPTION
In this exercise you will write a function named isInteger that determines whether or not the characters in a string represent a valid integer. When determining if a string represents an integer you should ignore any leading or trailing white space.

Once this white space is ignored, a string represents an integer if its length is at least 1 and it only contains digits, or if its first character is either + or - and the first character is followed by one or more characters, all of which are digits.

Write a main program that reads a string from the user and reports whether or not it represents an integer. Ensure that the main program will not run if the file containing your solution is imported into another program
