### To read a coordinate point in a XY coordinate system and determine its Quadrant

x=int(input('Enter the values for X'))

y=int(input('Enter the values for Y'))

if x > 0 and y > 0:
print ('x, y point lies in the First quandrant')

elif x < 0 and y > 0:
print ('x, y point lies in the Second quandrant')

elif x < 0 and y < 0:
print ('x, y point lies in the Third quandrant')

elif x > 0 and y < 0:
print ('x, y point lies in the Fourth quandrant')

elif x == 0 and y == 0:
print ('x, y point lies at the origin')

### Multiplication of two Matrices

X = [[4,1,7],[2,1,8],[3 ,7,1]];

for k in range(len(Y)):

### To check the number is composite number or not

n=int(input('Enter the number '))
factor=0
for i in range(1,n):

if factor>1:
print ('The number is a composite number!')
elif n==1:
print ('The number 1 is neither prime nor composite!')
else:
print ('This is not a composite number!')
