Control Flow: Conditionals - Lab

Introduction

Now that you have been introduced to conditionals, let's put your knowledge to test and create some conditional statements that selectively assign values to variables based on whether they pass the conditions we set.

Objectives

You will be able to:

• Use Python conditional statements

Instructions

Let's use our knowledge of variables and conditionals to assign values based on different conditions. Follow the instructions below to properly assign the values.

With the given code in the cell below, use what you know about numbers and conditionals to assign a value to my_number and follow the directions given in the comments below. Use this as a guide to structuring the rest of the problems in this lab.

number_50 = 50
my_number = None
if number_50 > 100:
    # if number_50 is greater than 100, assign the `my_number` variable to the number 100
elif number_50 > 50:
    # if number_50 is greater than 50, assign the `my_number` variable to the number 50
else:
    # else assign the `my_number` variable to 0

Below, use conditionals to tell whether it is hot outside or not. If it is hot, assign the string "It is so hot out!" to the variable is_it_hot. If it is not hot, assign the string "This is nothing! Bring on the heat.". For our purposes, anything over 80 degrees is considered hot.

temperature = 85
is_it_hot = None
# conditionals go here

Next, let's see what day of the week it is. There are 7 days in the week starting with Sunday at day 1 and ending with Saturday at day 7. Use conditional statements to assign the day of the week to the variable day_of_the_week based on the number below assigned to the variable today_is. For example, if the day is 2, we would assign day_of_the_week the value "Monday".

today_is = 4
day_of_the_week = None
# conditionals go here

Finally, let's take a string and see if it ends with a certain substring. If it does, assign the variable ends_with to True, and if it does not, assign it to False. For example, if have the string "School" and we want to know if it ends with the sub-string "cool". In this case it does not, so, we would assign False to the variable ends_with.

string = "Python"
sub_string = "on"
ends_with = None
# conditionals go here

Summary

Great! In this lab we saw how to use our knowedge of conditionals to selectively assign values based on a condition. We will start integrating conditionals in many more ways in our code and we will start to see how useful they can become in more complex problems.
