asalamualaikum warahmatullahi

wabarakatuh salam sejahtera untuk kita

semua ketemu lagi di video pengenalan

dasar pemrograman dengan materi hari ini

adalah variabel tipe data dan operasi

dasar J jadi dalam materi ini anda akan

belajar Apa itu variabel apa itu

jenis-jenis tipe data dan bagaimana

operasi dasar di dalam sebuah program

Python ya di sini kita menggunakan

program Python karena e sudah saya

jelaskan di pertemuan kemarin e program

tersebut cukup well knownown dan banyak

digunakan orang saat ini untuk melakukan

pemograman baik itu sifatnya data

analitis ataukah sifatnya pemograman ber

objek Oke selamat

menyimak kali ini kitaan belajar tentang

variabel data tipe apa sih variabel data

tipe itu jadi variabel Itu adalah sebuah

ee nama atau lokasi di mana kita bisa

menyimpan sebuah nilai contoh yang

gampang adalah tas ya Jadi kalau

misalkan anda punya tas itu Adah tas

variabel Oke dan dalam tas itu Anda bisa

menyimpan banyak hal kan mulai dari

pensil Ada pulpen ada buku tulis laptop

ya Misalnya laptop macam-macam nah

Sehingga dalam analogi tadi tas adalah

sebuah variabel dan pensil pulpen buku

itu adalah sebuah data oke Nah jadi

kalau dalam konsepnya adalah variabel

digunakan untuk menyimpan data yang

dapat direferensikan atau bisa

dimanipulasi dalam Python ya variabel

itu digunakan ketika kita mengign atau

sebuah menunjuk ya menunjuk sebuah nilai

pada sia variabel tersebut Contoh

misalkan 10 berarti kita membuat

variabel x dengan data atau nilai

sebanyak

10 data itu banyak sekali jenis-jenisnya

ada integer ini ya E misalnya 5- 10 ya

cuma Biasanya kalau integer itu dalam

konteks pemograman bilangan bulat ya

bilangan bulat arti engak P koma

kemudian kedua adalah FL atau decimal

number di sini ada 3,14 contohnya misal

atau

min0,001 juga termasuk bilangan FL atau

bilangan

desimal selanjutnya adalah string string

adalah dat t di mana kita di sini

menyampaikan e kata-kata ke dalam sebuah

program Python contoh misalkan hello

world hello dunia misalkan atau nama

Anda itu kan kata-kata ya terakhir ad

boance bance ini bukan makan makanan

yang apa namanya E digunakan apa yang

isinya dari daerah Bandung itu biasanya

kan ada buance ya Nah itu bukan tapi ini

adalah data yang menyatakan benar salah

Jadi ada nilai true fals-nya Nah nanti

biasanya dimasukkan ke dalam kalau

misalkan kita logika pemrograman nanti

Nah contoh program pyon itu sederhana di

sini Saya ingin menambahkan eh variabel

x = 10 dan variabel y = 5 kita sum atau

jumlah ya x + y nanti and kita tulis

printung sum ti2 kemudian kita masukin

nilai sum dari sini nanti akan muncul

nilainya 15 Ya kurang lebih seperti itu

nanti bisa e akan saya coba demokan e

tutorialnya ya

Oke next tentang integen Float integen

flot ini sebenarnya bilangan yang sering

dipakai dalam pemograman ya jadi eh

biasanya kedua bilangan ini akan dipakai

ketika kita menggunakan

eh sebuah operasi yang sifatnya numerik

dalam sebuah pengurang Python contoh

misalkan aritmatika tambah kurang kali

bagi modul operations exponentations dan

contohnya contohnya misalkan a = 5 + 3 *

2 atau B = 10 / 3 nah contoh-contoh ini

adalah sebuah operasi-operasi sifatnya

numerik ya numerik walaupun beberapa

masih agak asing tapi kita Jelaskan di

Next Video aja ya kita contoh fokus ke

hal ini nah contoh prag pynya gimana

misalkan kita punya ee a 3,14 nah 3,14

berarti termasuk bilangan flot ya b = 5

berarti termasuk bilangan integer dan

kalau kita tambahkan keduanya dan kita

minta print F eh sori print y e dari apa

variabel y Berarti akan muncul nanti

nilai 3,14 + 5 itu B basic dari sebuah

dasar

operasi next kita bicara tentang string

jadi string ini adalah eh kata jadi

bisanya

eh dalam konteks beberapa pemogramment

yang nanti disesuikan sama Id kita ya

integrated environment kemarin yang

sudah saya jelasin ya ID kita kan pakai

Python ya jadi

eh kita menggunakan apa namanya eh tools

namanya Jupiter Jupiter itu adalah

semacam tools yang dipakai di Google

kolaborator ya itu bisa digunakan untuk

menggunakan ID Python yait nanti Anda

bisa saya kasih apa namanya tutorialnya

ya jadi

eh bisa string ini biasanya memakai

single double atau triple codes jadi ada

single double atau triple tapi nanti

akan ada konteksnya Nah ini kan cuma

penjelasan ya Jadi nanti ada konteks

Kapan menggunakan single Kapan

menggunakan doble dan kapan menggunakan

triple itu nanti ada eh apa

penjelasannya dan juga biasanya ee ada

beberapa ee

istilah simbol yang digunak untuk

menyatakan itu string contoh

[Musik]

misalkan rep atau nanti ini ada apa

namanya konteks-onteks masing-masing ya

kemudiantoh misalkan kita peng

memasukkan nama John ya Dan kita

memasukkan greeting hell

johnkanakama sayaend jadi

[Musik]

di tanda double quote Ya kemudian plus

name Nah jadi nanti si Python akan

ngebaca bahwa kita pengin nyapa si Boni

nama nama yang ada di atas ini Hello

name-nya siapa si Boni berarti kalau

kita print greetings atau print

variableel greetings berarti jadi eh

hello Bunny ya nanti itu contoh kemudian

Bagaimana membuat variabel string dalam

sebuah program

Python Nah sekarang kita bicara balance

dan logical operations Nah jadi Balance

ini menyatakan

benar salah ya true or false ya benar

salah benar atau salah Nanti biasanya

ada beberapa logika yang dipakai di sini

walaupun kita pakai dasar dulu ya kita

belum masuk ke apa namanya ke logika

lanjutan nanti ada sesinya sendiri ya

Jadi kita ada istilah logical operators

ini ada n atau dan or atau or atau not

atau bukan ya Jadi nanti tiga ini biasa

dipakai di dalam pograman komputer

walaupun nanti ya nanti ada beberapa

looping juga ada beberapa istilahnya eh

pengulangan juga ya Ada for Ada apa

namanya untuk pengulangan ada if else

dan segala macamnya itu nanti akan

dijelaskan nextnya saja kita gak masuk

situ dulu ya Jadi kita sekarang belajar

apa variabel and paham variabel apa Data

tipe dan apa E operasi logika atau

numerik

Oke dengan demikian saya sudah video

pembajaran kali ini sampai jumpa di next

video Thank you sudah mendengarkan
