16. Exercise List

Use the interactive interpreter below to solve the following exercises.

1. Your current salary is $6500. Calculate your new salary with a 5% increase.

2. Display your name on the screen.

3. Calculate the sum of three variables.

4. What happens if you write text in the previous three variables?

5. Indicate the type of the following values: 5, 5.0, 4.3, -2, 100, 1.333, "10"

6. Experiment in the interactive Python interpreter using type(x) where x is each of the previous values.

7. Is it possible to calculate 2 to the power of one million?

8. Try assigning a variable greeting the string 'hello'.

9. Ask the user to enter their name and store it in another variable name.

10. Is it possible to join both strings of characters (strings) greeting and name?

11. Try to get the length of the character strings with len(x)

1. To calculate a 5% increase we can multiply our value by 1.05, so we have: 6500*1.05 = 6825.0. Then, after the increase, your salary will be $6825.

2. print("your name")

3. Suppose the variables x = 1, y = 2 and z = 3. To add them up, use the + symbol as follows: x + y + z, which results in the value 6.

4. Suppose now that the variables are x = "Me", y = "like" and z = "Python". If we add these variables we will get the answer: “MelikePython”.

5. The correct answers are int, float, float, int, int, float, and str.

6. To know the type of a variable, we use the type method as follows: type(5). This code will return <class 'int'> indicating that this variable is of integer type.

7. It is possible, just do 2**1000000 and you will get the result.

8. To create a string variable, we can write its value between single or double quotes: greeting = "Hello" or greeting = 'Hello'.

9. name = input("Enter your name: ")

10. Yes. When we add two strings, Python concatenates them. Let’s suppose the variables x = "greeting" and y = "name". If we add x + y, we will get “greetingname” as the answer.

11. Suppose we want the length of the string “greeting”. To find out, we do len(greeting) whose result is 6.
