Workbook 2- Baby? Child? Teenager? Adult?
Sasha wants a system to automatically work out where you are in your growth as a human based on your age. Sasha has done Pseudocode with some errors.....can you make it into Python code using operators.
.
a) Complete the code in this workbook based on the theory you have learnt
b) Copy the code into Python or the online version here: https://www.onlinegdb.com/online_python_compiler
print (" Welcome to my age checker"
age=int(input("Whats your age?"))
if age is equal to 0
print ("Are you a baby?")
elif age is less than or equal to 12
print (You are a child)
elif age is greater than 13 and less than 20:
print ("You are a teenager")
else age is greater than 19:
print ("You are an adult")

Workbook 4- Ellie's Code
Ellie's code is trying to make sense. She wants to ask them for two numbers and then by the choices they enter..... do the relevant calculation. But it doesnt work. Please fix and finish it
a) Complete the code in this workbook based on the theory you have learnt
b) Copy the code into Python or the online version here: https://www.onlinegdb.com/online_python_compiler
print ("Welcome to my Operators program")
num1=int(imput("Give me a first number")
num2=int(imput("Give me a second number)
print("Ok choose what you want to do with the numbers")
print ("Press 1 to add them")
print ("Press 2 to subtract 1st number and 2nd number")
print ("Press 3 to multiply 1st number and 2nd number")
print ("Press 4 to divide 1st number and 2nd number")
choices=input("What is your choice?")
if choice=="1":
print("The answer is",num1 plus num1)
elif choice=="2"
print("The answer is",???)
elif choice==3
print(The answer is",???)
elif choce=="4"
print("The answer is",???)

Workbook 5- Odd Or Even Number
Tommy wants a system to work out if a number if odd or even. He has had a go but is stuck
CLUE 1 which mathematical operator would help here?
CLUE 2 if the answer is 0 the number is even
a) Complete the code in this workbook based on the theory you have learnt
b) Copy the code into Python or the online version here: https://www.onlinegdb.com/online_python_compiler
answer=int(input("Is my number I am entering an even or odd number?
remain=answer??
if remain==??:
print ("The answer is an even number")
else:
print ("The answer is odd number")

In the following area you will:
6.5.1 be able to write programs that use arithmetic operators (addition, subtraction, division, multiplication, modulus, integer division, exponentiation)
6.5.2 be able to write programs that use relational operators (equal to, less than, greater than, not equal to, less than or equal to, greater than or equal to)
6.5.3 be able to write programs that use logical operators (AND, OR, NOT)
Arthimetic Operators
+ Addition x + y
- Subtraction x - y
* Multiplication x * y
/ Division x / y
% Modulus x % y
** Exponentiation x ** y
// Floor division x // y
Comparison Operators
== Equal x == y
!= Not equal x != y
> Greater than x > y
< Less than x < y
>= Greater than or equal to x >= y
<= Less than or equal to x <= y
Logical Operators
and Returns True if both statements are true x < 5 and x < 10
or Returns True if one of the statements is true x < 5 or x < 4
not Reverse the result, returns False if the result is true not(x < 5 and x < 10)
