+"""
+In this example, we are covering control flow in python
+
+
+Control flow at its lowest level lets us control the execution of code depending on data
+"""
+
+
+"""
+If statements are the most basic form of control flow, and allow us to conditionally execute code depending on a boolean
+expression
+"""
+
+age = 18
+
+if age >= 18:
+    # When the age is greater or equal to 18, this code is run
+    print("You are an adult")
+elif age >= 13:
+    # Otherwise, when the age is greater or equal to 13, this code is run
+    # you can chain multiple of these 'elif' conditions if you want
+    print("You are a teenager")
+else:
+    # And if neither of the above run, this else block is run
+    print("You are a literal child")
+
+
+
+
+bank_balance = 10000
+age = 27
+
+
+# Below, write the code for a bank to check if you are entitled to a mortgage
+# For sake of example, lets say you can get a mortgage when both:
+# a) You are above 25 years old 
+# b) You have over 50,000 in the bank
+# You can just print "Entitled" or "Not Entitled"
+
+
+
+
+# ^ Your code above here ^
+
+
+
+"""
+While loops are another critical part of control flow 
+
+they allow you to execute a block of code for as along as a boolean expression holds true
+"""
+
+
+"""
+The below code keeps on doubling a number until it passes a million
+"""
+
+number = 1 
+doubles_needed = 0
+
+while number < 1000000:
+    # Double the number 
+    number = number * 2
+    doubles_needed = doubles_needed + 1
+
+print("You needed to double", doubles_needed, "times to reach a million")
+
+
+# Exercise:
+# Below, write the code to perform an integer multiplication without using the python multiplication symbol *
+# You can use the fact that multiplication is a repeated addition to help you 
+
+number = 23
+times = 4
+result = 0
+
+# ^ Write your code above ^
+
+
+"""
+For loops are the final bit of control flow we are covering today
+
+technically, we do not need them as you can do anything that needs a for loop with a while loop
+"""
+
+vegetables = ["Carrot", "Lettuce", "Broccoli", "Cauliflower"]
+
+
+for vegetable in vegetables:
+    print(vegetable)
+
+
+# The above loop can be written as 
+
+index = 0 
+while index < len(vegetables):
+    vegetable = vegetables[index]
+    print(vegetable)
+
+    index = index + 1
+
+# But obviously, the for loop looks much nicer
+
+
+
+# For this next exercise, I will provide you with a list of numbers
+# I want you to create a for loop to square each one, and add it to a new list
+# You will need a for loop and the list.append() method
