Belajar python untuk Pemula

Belajar Phyton untuk Pemula dengan mengenal berbagai jenis dan bentuk, fungsi yang kami rangkum dibawah ini supaya memang tidak lupa untuk belajar. Jika anda ingin belajar yuk, kita belajar bersama-sama agar lebih mengetahui beberapa program yang dapat anda langsung praktekkan di Visual Code anda.
==============================================================================================================================

name = input("Siapa nama kamu?")
hobby = input ("Apa hobimu?")
print (name + " hobimu adalah " + hobby)
tahun = input (" Tahun lahir :")
tahun = int(tahun)
umur = 2023 - tahun
print ("umur kamu adalah " + str(umur))
age = 31
massage = f" umur kami {age}"
print(massage)
len() fungsinya untuk menghitung angka (fungsi)
course = "Belajar Bareng Topik"
print ( course.upper()) / Metode untuk huruf besar semua
#metode huruf kecil semua
course = "Belajar Bareng Topik"
print ( course.lower())
#metode depan huruf kapital
course = "Belajar Bareng Topik"
print ( course.title())
metode mengubah/mengganti dengan replace
course = "Belajar Bareng Topik"
print ( course.replace("Bareng","bersama" ))
melakukan cek apakah dalam kalimat ada sebuah kata yang dicari (bareng)
course = "Belajar python bareng topik"
language = "python"
print (language in course)

================== Operator Matematika==================

** = Pangkat
/ = pembagian (float)
// = pembagian bulat
% = Modulo ()
tandakurung
perpangkatan
perkalian atau pembagian
penjumlahan atau pengurangan

================== Math Modul==================

fungsi round digunakan untuk membulatkan
number = 5.8
number = number(round)
print (number)
import math
number = 5.4
number = math.sqrt (number)
print (number)
'python 3 math module'

==================Kondisi if atau percabangan menggunakan if==================

is_day = True
is_night=True
if is_day:
print ("Selamat Siang")
elif is_night:
print ("Selamat Malam")
else:
print ("selamat pagi)

==================operator perbandingan==================

!= tidak sama dengan
== sama dengan
>= lebih dari sama dengan
|| di python pakai or

nilai = 9
if nilai >= 8:
print ("nilai kamu A")
elif nilai >= 7:
print ("nilai kamu B")
elif nilai >= 6:
print ("nilai kamu C")
else:
print ("Silahkan belajar lagi dengan tekun")

==================operator logika==================

nama = "Topik Nugroho"
by_pass_validation = False
if len(nama) > 3 or by_pass_validation:
print("Welcome")
else:
print("Nama terlalu pendek")

================== Perulangan menggunakan While==================

index = 1
while kondisi:
print ("jalan")
print ("finish)
index = 1
while kondisi: / harus bernilai true baru dijalankan
print ("jalan")
print ("finish)
index = 1
while index <= 5: #apakah indek kurang dari 5 (true)
print ("*"* index)
index += 1
print("finish")

==================Buat Game.py==================

trying = 0
secret_number = 7
limit = 3
while trying < limit:
guess_number=input("Masukkan angka (1-9): ")
guess_number=int(guess_number)
if guess_number == secret_number:
print("Selamat, anda menang")
break

trying += 1

==================Aplikasi kalkulator==================

( + - * / exit)
command = ""
while command != "exit":
command=input( "Perintah : ")
if command =="exit":
break
if command !="+"and command !="-"and command !="*"and command !="/":
print ("perintah tidak dapat dikenali")
continue
a=int(input("Angka Pertama:"))
b=int(input("Angka Pertama:"))
if command =="+":
result= a + b
elif command =="-":
result= a - b
elif command =="*":
result= a * b
elif command =="/":
result= a / b
print (f"Hasil : {result}")
print ( "Terima Kasih Sudah Menggunakan Aplikasi Kami")

================== Perulangan For==================

numbers =[ 1,2,3,4,5]
for item in range (1,11,2) #mulai awal range dari angka 1, batas atas 11, dan kemudian, tambahnya dua
print(item)

==================list di python==================

kalau di program lain pakai Array bisa menampun banyak tipe data dari string, boolean dan angka dan biasanya isinya lebih sama bukan ketiganya
name =["Topik", "zelda", "nawa"]
print(name [1:3])
names =["Topik", "zelda", "nawa"]
for name in names:
print(f"Nama: {name}")

==================list Metode==================

numbers = [5,6,7,8,1]
numbers.append(99) #menambahkan angka baru dibelakang
numbers.insert(2, 100) # memasukkan di indek ke dua
numbers.pop (5) #menghilangkan indek ke lima
numbers.remove (8) #MENGHILANGKAN YANG ADA DI LIST
numbers.sort ()
print (numbers)

==================menjumlahkan list==================

numbers = [5,6,7,8,1]
init_number = 0
for number in numbers:
init_number= init_number + number
print(init_number)
#bisa cara pakai fungsi
numbers =[ 5,6,7,8,1]
total = sum(numbers)
print(total)
#mencari angka max
#carapertamamendapatkanangkapalingbesar
numbers = [ 5,6,7,8,1]
max_number = max(numbers)
print (max_number)
#carakeduamendapatkanangkapalingbesar
numbers = [ 5,6,7,8,1]
numbers.sort()
max_number = numbers[-1]
print (max_number)
#caraketigamendapatkanangkapalingbesar
numbers = [5, 6, 7, 8, 1]
max_number = numbers[0]
for number in numbers:
if number > max_number:
max_number= number
print(max_number)

================== tuple==================

numbers = ( 5,3,1,2,4,) #immutabel nilai nggak bisa diubah
numbers = numbers.index(3)
print(numbers)

==================unpack ==================

numbers = (1,2,3)
x = numbers [0]
y = numbers [1]
z = numbers [2]
print (x)
cara termudah menggunakan unpack
numbers = (1,2,3)
x,y,z = numbers
print (z)

==================Dictionary / Kamus Rubby Hash menggunakan kurung kurawal==================

user = {
"name": "Agung Setiawan",
"age" : 30,
"is_admin": True
}
name = user ["name"]
print ("")
print (name)
temp =user.get ("username","agungsetiawan")
user["username"] = "agung_setiawan"
user ["name"] = "Agung S"
user["username"] = "agung_setiawan"
print ("")
print (name)

================== Aplikasi Terbilang==================

numbers = input ("Masukkan Angka : ")
numbers_mapping = {
"1" : "satu",
"2" : "dua",
"3" : "tiga",
"4" : "empat",
"5" : "lima",
"6" : "enam",
"7" : "tujuh",
"8" : "delapan",
"9" : "sembilan",
"10" : "sepuluh",
}
output =" "
for n in numbers:
terbilang= numbers_mapping.get(n,"invalid")
output= output + terbilang +" "
print (output)

==================Emoji Converter==================

message = input (">>>")
emoji_mapping = {
":)" : "😀",
":D" : "😀",
":|" : "😀"
}
words = message.split(" ")
output =" "
for w in words:
output= output + emoji_mapping.get(w,w) +" "
print(output)
