Y10 AU – CT4 – Conditionals and Relational Operators

(1) Copy the code below into raspberry pi code editor

(2) Follow the instructions directly below each arrow comment block

(3) Add a subheading Do It Now into the OneNote

(4) Paste a screenshot of your complete code below the subheading

# DIN - Y10 AU - CT4

#-------------------- Global Variables ------------------

beatle = ""     # Initialising a variable called beatle

#-------------------- Main Program -----------------------

# Assigning an input to the beatle variable
beatle = input("Input the name of one of the Beatles: ")


#====> Complete a branched conditional sequence
#====> It will respond with correct if the user's response is
#====> paul, john, ringo or george

# DIN - Y10 AU - CT4

#-------------------- Global Variables ------------------

beatle = ""     # Initialising a variable called beatle

#-------------------- Main Program -----------------------

# Assigning an input to the beatle variable
beatle = input("Input the name of one of the Beatles: ")


#====> Complete a branched conditional sequence
#====> It will respond with correct if the user's response is

🎯 Objectives:

(1) We will be able to identify key features of a program that includes conditional sequences

(2) We will be able to describe the role of each relational operator

(3) We will be able to develop branched conditional sequences, involving both string and integer data

✍️ Code Annotation

(1) Screenshot the code below into OneNote

(2) Annotate it with the following:
————————————————————–

Initialisation of a variable
Assignment of a value to a variable
A prompt
Relational operator
Conditional sequence
Identify the type of data in each variable
Identify an example of casting
Overall, explain how the program works

# Activity 1 - Code Labelling Task

#-------------------- Global Variables ------------------

age = 0

#-------------------- Main Program -----------------------

name = input("Input your name: ")


age = int(input("Enter your age: "))


if age >= 11:
    print(f"Nice to meet you {name}")
    print(f"You can attend TGGS")

    
else:
    print(f"Nice to meet you {name}")
    print(f"Unfortunately you can't attend TGGS")

📖 Relational Operators

When testing a condition we place a relational operator between both values:

Operator	Meaning	Example (each would be True)
==	Equal to	if “a” == “a”:
!=	Not equal to	if “a” != “b”
>	Greater than	if 5 > 2:
<	Less than	if 2 < 5:
>=	Greater than or equal to	if 10 >= 9: or if 10 >= 10:
<=	Less than or equal to	if 9 <= 10: or if 9 <= 9:

🙋🏽‍♀️ Mini Whiteboard Activity

Access the mini-whiteboard app and join with the code your teacher has provided.

You will then answer from the following questions:
——————————————————————-

(1) What is the relational operator for greater than or equal to?

(2) What is the relational operator for not equal to?

(3) What is the relational operator for equal to?

(4) Why do we cast inputs to a different value?

(5) What three words are used in a branched conditional sequence?
