Solution

course = 'math'

Question-2

Create a variable named weight and assign the value 180.4 to it.

Solution

weight = 180.4

Question-3

Create a variable named number_of_apples and assign the value 45 to it.

Solution

number_of_apples = 45

Question-4

Write the code to convert the integer 1 to the string '1'

Solution

str(1)

Question-5

• Create a variable named x and assign the value 7 to it.

• Create a variable named y and assign the value 3 to it.

• Display the sum, difference, and product of 7 and 3 using the variables x and y.

Solution

x = 7
y = 3
print('Sum        :', x+y)
print('Difference :', x-y)
print('Product    :', x*y)

Question-6

• Create a variable named x and assign the value 7 to it.

• Create a variable named y and assign the value 3 to it.

• Create a variable named z, assign the value of x * y to it.

• Display z.

Solution

x = 7
y = 3
z = x*y
print('Product    :', z)

Question-7

• Create a variable named width and assign the value 10 to it.

• Create a variable named length and assign the value 50 to it.

  • These variables represent the sides of a rectangle.

• Create a variable named perimeter and assign the value of the rectangle’s perimeter to it.

• Create a variable named area and assign the value of the rectangle’s area to it.

• Display the following statements by using the variables width, length, perimeter and area.

  • The width of the garden is 10 ft.

  • The length of the garden is 50 ft.

  • The area of the rectangle is 500 square ft, indicating a large size.

  • The perimeter of the rectangle measures 120 ft, indicating that a considerable amount of fencing is required.

• Please avoid using the numbers 10 and 50 in your code, and remember to include appropriate punctuation.

Solution

width = 10
length = 50
perimeter = 2*(width+length)
area = width*length
print('The width of the garden is '+str(width)+' ft.')
print('The length of the garden is '+str(length)+' ft.')
print('The area of the rectangle is '+str(area)+' square ft, indicating a large size.')
print('The perimeter of the rectangle measures '+str(perimeter)+' ft, indicating that a considerable amount of fencing is required.')

Question-8

• Create a variable named x and assign the value 3 to it. (integer type)

• Without directly using the number 3 in your code (use variable x) print 3333 using three different code

• Assign 5 to x and verify if you obtain 5555 with the same code.

Solution

x = 3
print(str(x)*4)
print(str(x)+str(x)+str(x)+str(x))
print(x*1111)

print('-'*4)

x = 5
print(str(x)*4)
print(str(x)+str(x)+str(x)+str(x))
print(x*1111)
