a="apple"
b="number"
c=1
d=5
e=True
f=False
g=202.27

  a,b,e and f

  c and d

  a and b

  None of them are String

letter1="a"
letter2="bc"
print(letter1+letter2)

  bc

  a,bc

  abc, as the "+" will concatenate (join together) two strings.

def testaverage():
	testscore1=input("Enter test score 1:")
	testscore2=input("Enter test score 2")
	average=testscore1+testscore2/2
	print(average)

testaverage()

  Line 2 and 3, the input must be converted into an integer for the division on Line 4 to work

  Line 2 and 3 should have a double == in place in order for it to work correctly

  Actually, it will work correctly. There are no errors

  Line 4 should have a "two" instead of a 2, right at the end of the statement

  Boolean - because it either is a post code or isn't

  String - because it is alphanumeric (has both numbers and text)

  Float - because it has spaces

  Integer - because it contains numbers

  integer, because money is always an integer and you can then perform calculations

  boolean, because you either have a balance or are absolutely broke

  string, because it may contain a £ sign

  float, because it contains decimal points and you need to be able to perform calculations with it

def createusername():
	print("====Generating Username====")
	name=input("Enter First Name:")
	date of birth = input("Enter Date of Birth:")
	age=int(input("Enter your age: #"))
	print(name+ date of birth + age)

createusername()

  Line 5, the 'int' should be 'integer'

  Line 2, you cannot have capitals inside of a print statement

  Line 4, a variable name cannot have a space in it (e.g. date of birth should be dateofbirth)

  Line 8, it should call main() not createusername()

def main():
  firstname="Joe"
  age=33
  print("Your username could be:"+ firstname+age)
  
main()

  False

  True

def age_and_hours():
     age=int(input("What is your age?:"))
     if age>12:
          print("You are old!")
     else:
          print("Wow...your whole life ahead of you")
     hours=input("Enter the no. of hours you spend on homework per week:")
     if hours>10:
          print("Wow - you do a lot of independent study!")
     else:
          print("...are you sure that's enough to help you get ahead?!")

age_and_hours()

  age has been set up correctly, but hours has not (hours should also be integer or float)

  hours should not be an input

  hours has been set up correctly, but age has not (age should be a string input)

  Both age and hours are incorrectly coded

def pocketmoney():
     print("Keeping track of your pocket money")
     money=int(input("How much money do you have in the piggy bank?:"))
     spent=int(input("How much money have you spent?:"))
     left=money-spent
     print("You have this much money left:",left)
pocketmoney()

  It will ask you the next question, which is: "how much money have you spent?"

  It will correctly calculate the amount left, by subtracting 'spent' from one hundred

  ERROR: You cannot enter text when it is asking for integer input

  ERROR: You cannot write "pounds" you have to use the £ symbol after "one hundred" e.g. "one hundred £"

def guess():
  guess=int(input("Enter a number between 1 and 10:"))
  print("You have guessed:",guess)
  
guess()

  You have guessed: 20

  ERROR: You can only select between 1 and 10

  You have guessed: 2

  You have guessed: 10
