1 Hello, World! EMT1111: Logic and Problem Solving Fall 2016 Dr. Mendoza

2 LESSON 4 (Labs): Python Overview IV SIMPLE PYTHON PROGRAMS II

3 Lab Assignment 1 (poem2.py) Put the blocks below into the correct order to print a famous poem.

4 Lab Assignment 2 (mcdonalds.py) Put the blocks on the right into the correct order to declare the variables first and then print a following famous song.

5 Lab Assignment 3 (identity.py) Write a Python program to ask the user to enter his/her name, school, city, state, and country. Then the program should print a message like the following (using the values entered by the user): Alex is a student at CITY TECH in the city of Brooklyn on New York state. He is a citizen of the great country USA

6 Input and numeric values length = int(input("what is the length?")) width = int(input("what is the height?")) area = length * width print("area of a rectangle with dimensions", length, "x", width, "is:") print(area) What is the length? 3 What is the height? 4 Area of a rectangle with dimensions 3 x 4 is: 12 What is the length? 12 What is the height? 4 Area of a rectangle with dimensions 3 x 4 is: 48

7 Lab Assignment 4 (age.py) Modify the program to make it generic so that it will ask the user to input his/her name and birth year. Then it will calculate and print the age. name = "Zion" print (name) birthyear = 2000 age = birthyear print (age)

8 Lab Assignment 5 (weight.py) Write a Python program that will ask the user to enter his/her weight in pounds. Then it will convert the user s weight to kilograms and display it. To convert from pounds to kilograms, use the following formula: weightinpounds *

9 if Statement: Example age = 18 if age < 21: print ("You cannot drink yet") print ("You can t drive either") print ("Goodbye") age = 25 if age < 21: print ("You cannot drink yet") print ("You can t drive either") print ("Goodbye") You cannot drink yet You cannot drive yet Goodbye Goodbye

10 Logical Expressions

11 else Statement age = 18 if age < 21: print ("You cannot drink yet") print ("You can t drive either") else: print("drive responsibly") print ("Goodbye") age = 25 if age < 21: print ("You cannot drink yet") print ("You can t drive either") else: print ("Drink responsibly") print ("Drive responsibly") print ("Goodbye") You cannot drink yet You cannot drive yet Goodbye Drink responsibly Drive responsibly Goodbye

12 Lab Assignment 6 (price.py) Write a Python program to ask the user for the price of an item. Then, depending on the price entered by the user, the program should display one of the following messages: "Good price!", if the price is less than 50 "Regular price", otherwise (price is greater than or equal to 50)

13 Lab Assignment 7 (adult.py) Write a Python program to ask the user for his/her birth year. Based on the year entered, the program will calculate the user s age. Finally, depending on the user s age, the program should display one of the following messages: You are a minor, if the user is under 18 years of age You are an adult. Be responsible., otherwise

14 Lab Assignment 8 (today.py) Write a Python program to ask the user for the day of the week. Then, depending on the day entered by the user, the program should display one of the following messages: You have your EMT1111 class today. That means lots of Python programming!, if the day is Tuesday No Python programming today. Of course you can always practice at home., otherwise

15 Lab Assignment 9 (evenorodd.py) Write a program that ask the user for a number. The program should print out whether the input number is even or odd. HINT: Determine if the number is divisible using the modulus operator, that is %. The % operator returns the reminder of the integer division of two numbers. For example, 21%4 would result in 1 and 9%3 would evaluate to 0. Examples: >>> Give me an integer number --> 7 The number 7 is an odd number >>> Give me an integer number --> 20 The number 20 is an even number
