01 - Python (Foundation)

  It uses English keywords frequently where as other languages use punctuation.

  Python is a high-level, interpreted, interactive and object-oriented scripting language.

  All the answers listed in this selection are correct.

  Python is designed to be highly readable.

def letterGrade(score):
    if score >= 90:
        letter = 'A'
    else:   # grade must be B, C, D or F
        if score >= 80:
            letter = 'B'
        else:  # grade must be C, D or F
            if score >= 70:
                letter = 'C'
            else:    # grade must D or F
                if score >= 60:
                    letter = 'D'
                else:
                    letter = 'F'
    return letter

  The name of the function is letterGrade and it has two variables in use; score and letter

  In this code, 'score' is a function that is being passed to the variable 'letterGrade'

  The name of the variables in the function include letter,score and grade

  This function uses variables that are both strings and integers and therefore goes against python rules

  FALSE

  TRUE

  Slice

  List

  Integer

  String

  Error

  Hello World!

  11

  str

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

  casting (converting age - which is input as a string - into an integer)

  checking to see if the variable 'age' is an int (integer)

  checking to see if the variable 'int' is age related

  casting (converting age into a string)

print("Test" + "Track")
print("Door" + "man")
print("4" + "chan")

  concatenation

  addition

  errors

  correlation

num = input("Enter a number: ")
mod = num * 2
if mod > 0:
    print("You picked an odd number.")
else:
    print("You picked an even number.")

  You piked an odd number AND you picked an even number

  You picked an odd number

  You picked an even number

  Error

  Line 1 needs to be changed to: num = odd or even ("Enter a number")

  Nothing, the code works perfectly.

  Line 3 needs to be change d to if mod < 0:

  Line 2 needs to be changed to use MOD e.g. mod = num % 2

  interpreter / before the code is written

  compiler / compile time

  assembler / run time

   interpreter/ run time

balance=300
if balance < 0:
    transfer = -balance
    backupAccount = backupAccount - transfer
    balance = balance + transfer
print(balance)

  Because the condition outlined in the if statement on line 2 is true

  Because there is an error on line 1 and 5

  Because the condition outlined on line 2 is not true so that part of code does not run

  Because the transfer amount is always 0, which means 300+0 = 300

count = 0
while (count < 9):
   print 'The count is:', count
   ???????????????????????

print "Good bye!"

  count = count - 1

  count = count + 1

  count/0

  count = 0 + 1

while True:
    print("hello world")

  It will print the word "true" to the screen before it prints "Hello World"

  It will print "hello world" once

  It is an infinite loop

  It will only print "hello world" if the input is "true"
