3-2-Investigate

Task – Investigate:

This task contains example code and 6 questions.
Use comments to answer the investigate questions on the example code.

Learning Objectives/Goals

Students will learn to interpret, trace, identify and create python code that uses:

Concept	Explanation	Python Code	Examples
Strings	The text data type. All string data is treated as text, even if it is numerical characters.	“string goes here”	“This is a string”
Variable assignment	Putting data into a variable.	=	num1 = 10 name = “Andy”
Concatenation	Joining string literals (text in speech marks that prints exactly as it appears in the code) to the contents of variables in output, or joining the contents of variables together. There are several ways of doing this, but I’ve used the plus symbol in my exercises.	+	print(“Hello ” + name) fullName = firstName + lastName
Input	Collecting data for processing. In these examples we collect input that the user types on the keyboard but computers collect input in lots of ways – as sound, mouse movements, with sensors etc. Input must ALWAYS be assigned to a variable or it will not be stored. All input is treated as strings. Any input that needs to be treated as a number must be cast into the new format.	variableName = input()	print(“What’s your name?”) name = input() print(“Guess the secret number” guess = int(input())

Variable assignment – Using the ‘=’ symbol to store data in a variable. You can find out more about variable assigment here
Concatenation – joining the contents of variables to other variables and/or strings in output. You can find out more about concantenation here

Help! My Code Doesn’t Work!

Make sure that you check for the following things:

you have put the brackets after the input command
you have typed the variable name exactly the same (including caps), every time
There is a variable on the left of each assignment
You have used a single = for assignment
You have used the + symbol to concatenate (join).
