D522 PYTHON FOR IT AUTOMATION PA FULLY
SOLVED ASSESSMENT PAPER GRADED A+
◉ Outside a function.
Answer: Global code that exists outside of a function and runs
directly, with no need to be specifically called by a function.
◉ Local vs. Global Variables.
Answer: Local variables take precedence over global variables inside
functions.
Global variables can be used by any functions in your code.
Local variables can only be used in the function they were created
from.
◉ global [variable] keyword.
Answer: This keyword is used to call a global variable inside of a
function.
Ex:
ip1 = "10.1.1.1"
,def sample()
global ip1
print(ip1)
sample()
Output: "10.1.1.1"
◉ What is the primary characteristic of Python variables?.
Answer: Variables are created as soon as a value is assigned to them.
◉ Unpacking variables.
Answer: Extracting elements from iterable objects and assigning
them to individual variables.
◉ How can multiple Python variables of different types be output
using the print() function?.
Answer: Using commas
◉ Python membership operator.
Answer: in
(ex: result = user_input in usernames. If the input contains a match
in a list of usernames, it prints "True").
, ◉ Python operator precedence.
Answer: Parenthesis - () - Highest precedence.
Exponentiation - ** - Next highest precedence.
Multiplication, division, floor division, modulus - * / // % - Same
precedence, read from left to right.
Addition and subtraction - + - - Same precedence, read from left to
right.
Bitwise shift - << >> - Lower than arithmetic operations.
Bitwise AND - & - Lower than bit shifts.
Bitwise XOR - ^ - Lower than AND.
Bitwise OR - | - Lowest precedence.
◉ Parenthesis precedence.
Answer: Has the highest precedence.
◉ Exponentiation precedence.
Answer: Has the next highest precedence below parenthesis.
◉ Multiplication, division, floor division, modulus precedence.
Answer: Has same precedence and is evaluated left to right. This
precedence is lower than exponentiation.
