Variable Questions:

Question 1

Make a variable and assign a number to it (any number you like). Then display your variable using print.

Question 2

Modify your variable, either by replacing the old value with a new value, or by adding something to the old value. Display the new value using print.

Question 3

Make another variable and assign a string (some text) to it.
Then display it using print.

Question 4

Make a variable for DaysPerWeek, HoursPerDay, and MinutesPerHour (or make up your own names), and then multiply them together.

Question 5

People are always saying there’s not enough time to get everything done. How many minutes would there be in a week if there were 26 hours in a day? (Hint: Change the HoursPerDay variable.)

Question 6: (Sample Question)

Write a program to solve the following question: Three people ate dinner at a restaurant and want to split the bill. The total is $35.27, and they want to leave a 15 percent tip. How much should each person pay?

Hint: you can create three variables to start:

>>> people = 3
>>> total = 35.27
>>> tip_percent = 0.15

then you could get the result by calculating step-by-step as following:

>>> tip = total * tip_percent
>>> final_total = total + tip
>>> each = final_total / people
>>> print(each)

Data Type Questions:

Question 7.

Use float() to create a number from a string like ‘12.34’. Make sure the result is really a number!

Question 8.

Try using int() to create an integer from a decimal number like 56.78. Did the answer get rounded up or down?

Question 9.

Try using int() to create an integer from a string. Make sure the result is really an integer!
