+A. Struktur Data dalam python 
+1. String
+2. Integer
+3. Float
+
+4. Date
+5. DateTime
+   menggunakan module datetime
+   import datetime
+   dt = datetme.date(year, month, day)
+   dt_time = datetme.datetime(year, month, day, hour, minutes, seconds.miliseconds)
+   
+   Import Fungsi
+    >>> import datetime
+    >>> datetime.datetime.now()
+    >>> dt = datetime.date(2025,10,2) 
+    >>> print(dt)
+    2025-10-02
+    >>> from datetime import date
+    >>> dt = date(2025,10,2) 
+    >>> print(dt)
+    2025-10-02
+
+    Fungsi yang berhubungan dengan Date
+    strftime(format) konversi menjadi string yang terformat %d, %m, %Y %H %M %S
+    strptime("date string", format) konversi dari string ke datetime
+        dt_from_str = datetime.datetime.strptime('2025-08-05',"%Y-%m-%d") 
+
+6. List/Array
+   alist = [1,2,3,4,5,6]
+   blist = [5,6,7]
+   index list dimulai 0
+
+   Operasi
+   a. Append alist.append(7)
+   b. Insert alist.insert(0, 0)
+   c. Delete del alist[index]
+        alist.pop(index) menghapus dan menyimpan ke variable lain
+7. Tuple
+    atuple = (1,2,3,4,5,6)
+    btuple = (5,6,7)
+    index tuple dimulai 0
+   
+8. Dictionary terdiri dari key dan value
+    dictionary = {"a": 1, "b": 2, "c": 3}
+    dictionary = dict(a=1,
+                  b=2,
+                  c=3}
+                
+    Campuran:
+         dictionary = {"a": 1, "b": [1,2,3,4,5,6], "c": (1,2,3,4,5,6), "d":{"d1":"D1", "d2":1}}
+B. Variable
+
+C. def -> function 
+    def kali(a, b):
+        return a*b
+
+    def kali1(a=1, b=2):
+        return a*b
+
+    def kali2(*arg):
+        c = 1
+        for i in arg:
+            c = c * i
+        return c
+
+    def kali3(a=1, b=2):
+        c = a*b
+        return c
+
+    def kali4(**kwarg):
+        c = 1
+        for kw in kwarg:
+            c = c * kwarg[kw]
+        return c
+
+
+
+D. class -> Object
+
+E. Framework
+
+F. Perintah standard
+    type(obj) Mendafatkan type variable/object
+    print(obj,)
+    str(obj) merubah menjadi type string
+    int(obj) meribah menjadi type obj
+    float(obj) merubah type menjadi Float
+    dir(obj) melihat daftar fungsi/attribut dalam suatu object
+    hasattr(obj, name) cek object mempunyai attribute 
+    getattr(obj, name) mengambil attribute biasanya kedalam suatu variable
