  • Create the birthyear variable using the age variable.

  • Design a name tag as given below.

  • There is a space between each asterisk in the first and last lines.

Michael Jordan played basketball in the NBA. In 2024, he is 61 years old, and his height is 1.98 meters.

Sample Output:

Question-2#

By using the variables \(x\) and \(y\) given below, print 353535 using 4 different pieces of code.

x, y = 3, 5

Question-3#

Print the statement I went to Italy in 2015. using the country and year variables below.

country = 'Italy'
year = 2015

Warning: There is no space before the period.

Question-4: Circle#

Create a variable named r and assign the value of \(5\) to it.

  • Print the area and perimeter of the circle with a radius equal to r.

  • Round them to the nearest hundredth.

  • Hint:

    • Perimeter = \(2\pi r\), Area = \(\pi r^2\)

    • Import \(\pi\) from a module.

  • Output:

    • Perimeter: 31.42

    • Area : 78.54

Question-5: U-Shape#

Print the letter U using the character + and the variable horizontal.

horizontal = 3

  • The vertical left and right parts of U have five + characters each.

  • The variable horizontal represents the number of + characters with one space between them in the bottom horizontal part.

Examples The U shape is formed using + characters. The first four rows each contain two + characters with a varying number of spaces between them, depending on the horizontal variable's value. The final row (fifth) contains a number of + characters equal to the horizontal variable's value, with one space separating each +.

Question-6: V-Shape#

Print the following using the character *, spaces and the variable n=5 to represent the number of * characters in each block.

In the first row, there are two blocks of n stars with 7n spaces between them.In the second row, there are two blocks of n stars with 5n spaces between them.In the third row, there are two blocks of n stars with 3n spaces between them.In the fourth row, there are two blocks of n stars with n spaces between them.In the fifth (last) row, there is a single block of n stars.

Question-7: H-Shape#

Print the following ‘H’ shapes using the characters ‘+’, ‘ ‘, ‘-’, and the variable number_dash.

number_dash = 5

  • The number of ‘-’ characters in the middle line is represented by the variable ‘number_dash’.

Examples In the first and third (last) rows, there are two + characters with a certain number of spaces between them, depending on the number_dash variable. In the second row, there are two + characters with a certain number of dashes between them, also determined by the number_dash variable. There is a spaceafter each dash.

Question-8: Receipt Generator#

The following code generates a basic store receipt. Improve its appereance by adding separators (dashes -) and formatting the price, tax, tip, and discount details to make it look more professional, similar to real receipts.

from datetime import datetime
current_date_time = datetime.now().strftime('%Y-%m-%d %H:%M:%S')  # string object

restaurant_name = 'Olive Garden'
price = 100  
tax = 0.08
tip = 0.15
discount = 7

tax_amount = tax*price
tip_amount = tip*price

total = price + tax_amount + tip_amount - discount

print(restaurant_name) 
print(current_date_time)
print('Total          :', total)
