+list [1,2,3,4,5] or ['abbas', 2 ,-10 , 2.65]
+dictionary: {'name': abbas , 'l_name': 'gholi'}
+set: like set but dont have duplications  
+
+```python
+print(type(var)) # Return Varible Type
+```

+
+strings is imutable (can,t change after set string with str[0]='i')
+
+```python
+string="this is string about abbas gholi #1"
+print(string[0]) # --> Return t
+print(string[1:3]) # --> Return his
+print(string[-1]) # --> Return 1
+# [start : end]
+```
+
+```python
+string='012345678'
+print(string[5]) # --> return '5'
