# Basic Syntax
print("Hello World")

# Quotation in Python

# Assigning Value to Variable

# Standart Data Types
# There are several data types: Number, String, List, Tuple, Dictionary
# Number Consist of int, float, and complex
              
# Python String
sedotan = "Panjang Banget huehuehue "
print(sedotan)  # Print complete List / sentence
print(sedotan[0]) # Print 1st index of List (1st char)
print(sedotan[4:9])

print(sedotan[-1])
print(sedotan + "dan bahannya stainless skill xixixi") 
print(sedotan*2)

print("Nama gue %s umur gue %d" % ("siapa dah", 23))

      
# Python List
# Python Lists are similar to arrays in C programming
# all items can be different data type and can be updated
contoh_list = ["bisa string", 20, 90.0, True,'john', 'mayer']
print(contoh_list)
print(contoh_list[0]) # Print first list
print(contoh_list[2:5])
print(contoh_list[:4])
print(contoh_list[2:])
print(contoh_list*2)
print(contoh_list[-1])
      
# Python Tuple
# Just like list but can not be updated/changed
Contoh_Tuple  = ("Contoh tuple", 20, 9.0, False)
print(Contoh_Tuple)
# sisanya kayak list dan string, gue males ngetiknya hehe

      
# Python Dictionary
dict = {}
print(dict)
dict['satu'] = "This is one's value"
dict[2] = "This is two's value"
print(dict)
print(dict.values())
print(dict.keys())
print(dict['satu']) # Print dict one's value
print(dict['2'])
Big_dict = {'nama': "Johny Deep", "code": 6969, 'dept': "Videos Engineer"}
      
# Example Dictionary

total_pajak = total_harga * 0.05

# Python Set
contoh_set = {"baju", "kaos", "sempak", "celana"} # Mutable
contoh_frozen_set = ({"gope","seceng","goceng"}) # Immutable
             
# Data Conversion
Duit = "Goceng"
in_number = 5000
print(Duit + in_number) # Error
print(Duit + str(in_number)) # Change it to string

# Variable Global dan Lokal
# Lokal
x = 911
