Python Camp Session 2: Computational Thinking and Problem Solving Data Types Variables Sequence / Selection / Iteration

Dry Run this program age = input(“What is your age? “) double = age + age print(double) Starter - have students guess, then test, then discuss reasons for the error.

Solution 1 age = input(“What is your age? “) age = int(age) double = age + age print(double) Starter - have students guess, then test, then discuss reasons for the error.

Solution 2 age = int( input(“What is your age? “) ) double = age + age print(double) Starter - have students guess, then test, then discuss reasons for the error.

+ - * / ** % Arithmetic Operators num1 = input(”Enter a number: ”) print(num1 + num2) Find out what each of these does: + - * / ** %

Data Types Type Casting Meaning integer int() whole number float decimal fraction string str() text boolean bool() yes / no true / false Introduce data types and casting. Test out a few times.

Data Types a = 3 type(a) a = 3.0 a = “3” a = True

Data Types a = 3 type(a) a = 3.0 a = “3” a = True a = 3 type(a) a = int(“3”) a = “True”

Multiple Choice Quiz pi.mwclarkson.co.uk York Python Camp Programming Resources Programs Python Quiz.py Provide multiple choice quiz. Students adjust question and answer, include some numeric questions (focus on casting), task to duplicate for further questions and add an IF statement to give a grade.
