Module 3 - Chapter 2
Ini adalah chapter tentang "conditions" di Python.
== ...> equal to
!= ...> not equal to
>...> greater than
< .... less than
>= ... greater than equal to
minMarks = 30
studentMarks = float(input('enter your mark: '))
if studentMarks > minMarks:
print("you are eligible")
else:
print("you are not eligible")
Run Python File:
enter your mark: 40
you are eligible
enter your mark: 12
you are not eligible
elif studentMarks >= 25:
minMarks = 30
studentMarks = float(input('enter your mark: '))
if studentMarks > minMarks:
print("you are eligible")
elif studentMarks >= 25:
print("you have been put in waiting list")25
else:
print("you are not eligible")
Run Python File:
enter your mark: 25
you have been put in waiting list
enter your mark: 31
you are eligible
urutan:
if
elif
else
Which of these are conditional operators in Python? Choose three.
- equal to
- greater than
- less or equal to
----------------------------------------------
Module 3, Chapter 3
Ada dua type Loops:
1) Iterative
- doing over and over or repetition.
- for
2) Conditional
- while
# Iteration / for loop
for i in 'string':
print(i)
# conditional / while loop
i = 1
while i <= 50:
print(i)
i += 1 # i = i + 1
Run Python File:
s
t
r
i
n
g

Which of these is used to denote a list in Python? Choose one.
- [ ]
-------------------------------------------------------
Module 3, Chapter 4
List adalah connection of similar objects
print(fruits)
fruits = [
'apple', # 0
'banana', # 1
'pear', # 2
'strawberries', # 3
]
print(fruits)
Run Python File:
['apple', 'banana', 'pear', 'strawberries']
print(fruits[2])
fruits = [
'apple', # 0
'banana', # 1
'pear', # 2
'strawberries', # 3
]
print(fruits[2])
Run Python File:
pear
print(fruits[:2])
fruits = [
'apple', # 0
'banana', # 1
'pear', # 2
'strawberries', # 3
]
print(fruits[:2])
Run Python File:
['apple', 'banana']
-----------------------------------------
Module 3, Chapter 5
Mari kita mempelajari List operation
We can change value from 'd' to 'c'
characters = ['a', 'b', 'd', 'd']
print(characters)
characters [2] = 'c'
print(characters)
Run Python File:
['a', 'b', 'd', 'd']...> there are two 'd'
['a', 'b', 'c', 'd']...> 'd' is replaced by 'c'
>>> characters = ['a', 'b', 'd', 'd']
>>> len(characters)
4
>>> characters.append('f')
>>> characters
['a', 'b', 'd', 'd', 'f']
>>> characters.remove('f')
>>> characters
['a', 'b', 'd', 'd']
['a', 'b', 'd', 'd']
>>> characters.pop(3)
'd'
>>> 'b' in characters
True
>>> 'z' in characters
False
Which of these is not one of the list operations in Python? Drag the correct answer into the space provided.
- characters.insert()
-----------------------------------------------------------------------
Module 3, Chapter 6
Bubble Sort:
Bubble sort adalah simple sorting algorithm
list = [8, 3, 1, 4]
print("Original list:", list)
length = len(list)
for i in range(length):
for j in range(0, length - i - 1):
if list[j] > list[j + 1]:
list[j], list[j + 1] = list[j + 1], list[j]
print("Sorted list (ascending order):", list)
Run Python File:
Original list: [8, 3, 1, 4]
Sorted list (ascending order): [1, 3, 4, 8]
-----------------------------------------------
Module 3, chapter 7
Beberapa operators akan kita pelajari
>>> a = 12
>>> if (a > 6) and (a < 20):
... print(a)
...
12
Q1: cari binary angka 13
- bagi angka 13 dengan 2: 13/2= 6 ...> reminder 1....> first binary.
- then, 6/2 = 3 ...> reminder 0 ...> second binary
- then, 3/2 = 1 ...> reminder 1 ...> third binary
- kemudian, 1/2 = 0 ...> `reminder 1 ...> fourth binary
Untuk mengetahui binary angka 13, dilihat dari bawah (belakang) atau dari langkah ke 4 (fourth binary): 1101
>>> bin(13)
'0b1101' ...> 1101
Q2: cari angka berapa dari binary 0b1100 atau 1100?
- mulai dari sebelah kanan, yaitu 0
- decimal equivalent 0 = 0 x 2^0 = 0
- decimal equivalent 0 = 0 x 2^1 = 0
- decimal equivalent 1 = 1 x 2^2 = 4
- decimal equivalent 1 = 1 x 2^3 = 8
Then, 0 + 0 + 4 + 8 = 12
Q3: 12|13 ...> 12 or 13
binary 12 = 1100
binary 13 = 1101
-------------------------------
= 1101
Convert to value from right: 1(2*0) + 0(2*1) + 1(2*2) + 1(2*3) = 1+0+4+8 = 13
proved by VSC:
>>> 12|13
13
Q4, Now find 12&13
binary 12 = 1100
binary 13 = 1101
--------------------------
= 1100
convert to value from right: 0(2*0) + 0(2*1) + 1(2*2) + 1(2*3) = 0 + 0 + 4 + 8 =12
proved by VSC:
>>> 12 & 13
12
Q5, find 12 xor 13
>>> 12 ^ 13

True or False: A bubble sort consists of three types of loop.
- False
- True: one type of loop.
The followings are the key points from this module:
Boolean logic refers to the idea that all values are either true or false.
Some boolean operations that were examined include:
and
or
Xor
Some conditional operators that were mentioned include:
Equals to which is written as ==.
Not equals to which is written as !=.
Greater than and Less than which are written as > and < respectively.
Greater than or equals to which is written as >=.
Less than or equals to which is written as <=.
The following are the two types of Loops examined in this module:
Iterative loop (For loop).
Conditional loop (While loop).
Lists are collections of similar objects and are denoted with "[ ]".
The different operations that can be run on lists include:
Changing character(s) of a list.
Len (characters) -- To check the length of a list.
character.append ('e') -- To add the character "e" to the end of a list.
character.reverse -- To reverse the order of characters in a list.
Bubble Sort refers to a simple algorithm that goes over an array and sorts it into the correct order.
