Donkey work =
repetition = iteration –
loops – inside it there
are conditions

Further programming
• Lab exercises
– Let's go downstairs to the basement computer
labs!
• - learn prcticaly
• What next?
– Lists , Dictionaries , Algorithms etc.

Essential Questions
• Essential Questions: learn
practically by designing a program
which include 1- the logical
operators and give some
examples. 2- Comparing between
if & switch statements and give
some examples. 3- Write the
general syntax of the conditional
statements (if & switch). Eng. & Educator Osama
Ghandour

Evidence of Learning:
Create a project with a
programming language
“Python” using Variables,
Constants Arithmetic, and
Assignment operators.

if
 If statement: Executes a group of
statements only if a certain condition is
true. Otherwise, the statements are
skipped.
 Syntax:
if condition:
statements
 Example:
gpa = 3.4
if gpa > 2.0:
print "Your application is accepted."
Ghandour

16
if/else
 if/else statement: Executes one block of statements if a certain
condition is True, and a second block of statements if it is False.
 Syntax:
if condition:
statements
else:
statements
 Example:
gpa = 1.4
if gpa > 2.0:
print "Welcome to Mars University!"
else:
print "Your application is denied."
 Multiple conditions can be chained with elif ("else if"):
if condition:
statements
elif condition:
statements
else:
statements Eng. & Educator Osama
Ghandour

17
while
 while loop: Executes a group of statements as long as a condition
is True.
 good for indefinite loops (repeat an unknown number of times)
 Syntax:
while condition:
statements
 Example:
number = 1
while number < 200:
print number,
number = number * 2
 Output:
1 2 4 8 16 32 64 128
Ghandour

18
Logic
 Many logical expressions use relational operators:
 Logical expressions can be combined with logical operators:
 Exercise: Write code to display and count the factors of a number.
Operator Example Result
and 9 != 6 and 2 < 3 True
or 2 == 3 or -1 < 5 True
not not 7 > 0 False
Operator Meaning Example Result
== equals 1 + 1 == 2 True
!= does not equal 3.2 != 2.5 True
< less than 10 < 5 False
> greater than 10 > 5 True
<= less than or equal to 126 <= 100 False
>= greater than or equal to 5.0 >= 5.0 True

Exercise :
19
• Write a program to prompt for a score between 0.0
and 1.0.
If the score is out of range, print an error message.
If the score is between 0.0 and 1.0,
print a grade using the following table:
• Score Grade • >= 0.9 A
• >= 0.8 B
• >= 0.7 C
• >= 0.6 D
• < 0.6 F
• ~~~ • Enter score: 0.95 A ~~
• Enter score: perfect • Bad score
• Enter score: 10.0 • Bad score
• Enter score: 0.75 • C • Enter score: 0.5 • F

Dictionaries
 Dictionaries
• Dictionaries: curly brackets { }
• What is dictionary?
• Refer value through key; “associative arrays”
• Like an array indexed by a string
• An unordered set of key: value pairs
• Values of any type; keys of almost any type
• {"name":"Guido", "age":43, ("hello","world"):1,
42:"yes", "flag": ["red","white","blue"]}
• d = { "foo" : 1, "bar" : 2 } print d["bar"] # 2
some_dict = {} some_dict["foo"] = "yow!" print
some_dict.keys() # ["foo"]

functions
 Functions in Python
 Defining functions.
 Return values.
 Local variables.
 Built-in functions.
 Functions of functions.
 Passing lists, dictionaries, and
keywords to functions.
23
Ghandour

functions
24
Why functions?
• It may not be clear why it is worth the trouble to divide a
program into functions. • There are several reasons: •
Creating a new function gives you an opportunity to name a
group of statements, which makes your program easier to
read, understand, and debug. • Functions can make a
program smaller by eliminating repetitive code. Later, if you
make a change, you only have to make it in one place. •
Dividing a long program into functions allows you to debug
the parts one at a time and then assemble them into a
working whole. Well-designed functions are often useful for
many programs. Once you write and debug one, you can
reuse it
Ghandour

functions
 Define a Function: def
 Define them in the file above the point
they're used Body of the function
should be indented consistently (4
spaces is typical in Python) Example:
square.py def square(n): return n*n
 print "The square of 3 is ", print
square(3)
 Output: The square of 3 is 9
25
Ghandour

functions
 The def statement
 The def statement is executed (that's
why functions have to be defined
before they're used) def creates an
object and assigns a name to
reference it; the function could be
assigned another name, function
names can be stored in a list, etc.
Can put a def statement inside an if
statement, etc!
26
Ghandour

functions
27
Ghandour

functions
Functions, Procedures
def name(arg1, arg2, ...):
"""documentation"""#
optional doc string
statements
return # from procedure
return expression # from
function
28
Ghandour

functions
 More about functions
 • Arguments are optional. Multiple
arguments are separated by commas “ , ”.
• If there's no return statement, then
“None” is returned. Return values can be
simple types or tuples. Return values may
be ignored by the caller. • Functions are
“typeless.” Can call with arguments of any
type, so long as the operations in the
function can be applied to the arguments.
This is considered a good thing in Python

Home work (s. proj.) 1
you studied in physics about
electric power and in your capstone about
saving wasted energy so design a flowchart
for Arduino control circuit to save the
consumed energy in electric power circuit .
Note : an ideal electric system has power
factor PF=0.999 and very low reactive
power. using logical operators and
conditional statements beside a function
with parameters , calling it to complete a
program .

If you do not feel happy, smile
and pretend to be happy.
• Smiling produces seratonin
which is a neurotransmitter
linked with feelings of
happiness
