Tuples unpacking in Python

 

Tuples:

my_tup = [(1,2),(2,3),(4,5),(6,7),(8,9)]

for tup in my_tup:

    print(tup)


Output:

(1, 2)
(2, 3)
(4, 5)
(6, 7)
(8, 9)

Tuple unpacking methods:

Method-1: using (a,b) 

my_tup = [(1,2),(2,3),(4,5),(6,7),(8,9)]

for a,b in my_tup:
    print(a)
    print(b)

Output:

1
2
2
3
4
5
6
7
8
9


Dictionaries:

my_dict = {'Apple':2, 'Grapes':1, 'Orange':1 }

for dict in my_dict:
    print(dict)

Output:

Apple
Grapes
Orange

Note: By default, it prints only the Keys but not the values.

To print both the keys and pairs we have to use items() 
like 
my_dict.items()
my_dict.values()

my_dict = {'Apple':2, 'Grapes':1, 'Orange':1 }

for dict in my_dict.items():
    print(dict)
 
Output:

('Apple', 2)
('Grapes', 1)
('Orange', 1)

Again Here you could use tuple unpacking technique.

my_dict = {'Apple':2, 'Grapes':1, 'Orange':1 }

for key,value in my_dict.items():
    print(key)
    print(value)

Output:

Apple
2
Grapes
1
Orange
1

Tuples in Python

 Tuples Basically Tuples in Python are very similar to Lists, but, Tuples are immutable which means that they can not be modified/changed. We generally use Tuples to make sure the values are not changed like, dates, Year, and days of the week or dates on a Calendar.  Creating a Tuple: >>> my_t1=(1,2,3) >>> my_t2=('one','two','three') >>> my_t1 (1, 2, 3) >>> my_t2 ('one', 'two', 'three') -- check the length of tupple: >>> len(my_t1) 3 >>> len(my_t2) 3 -- Tuples can have mixed objects as like Lists. >>> my_t3=(1,'two',3,'four') >>> my_t3 (1, 'two', 3, 'four') -- indexing with tuples  >>> my_t3=(1,'two',3,'four') >>> my_t3[2] 3 Immutable Tuples We can not modify the value. Here is the example: >>> my_t3=(1,'two',3,'four') >>> my_t3[2]=4 Traceback (most recent call last):  ...

Auditing in Oracle database

Unified Auditing: Oracle Database 12c Release 1 introduces a new auditing feature called Unified Auditing (12.1). Oracle Unified Auditing modifies the database's fundamental auditing capabilities. In earlier versions of Oracle, each component has its own audit trail. With unified auditing, all auditing is compiled into a single repository and view. Due to the fact that all audit data is now in a single location and a single format, there is a double simplification as a result. This data is made available in a consistent format in the UNIFIED AUDIT TRAIL data dictionary view, which is made possible by the unified audit trail, which is stored in a read-only table in the AUDSYS schema in the SYSAUX tablespace.  DBAs can build audit rules and then assign them to various users using Oracle 12c Unified Auditing, which has the same advantages as giving users varying system capabilities based on their responsibilities. The unified_audit_trail database will contain all of the audit records....

Boolean in Python

What is a Boolean? Ture or False (Make sure to use initial letter as a capital) For Example, >>> True True >>> true Traceback (most recent call last):   File "<stdin>", line 1, in <module> NameError: name 'true' is not defined Examples: >>> x= True >>> type(x) <class 'bool'> >>> 9 > 8 True >>> 8> 9 False  How to define/assign a variable without value? >>> x Traceback (most recent call last):   File "<stdin>", line 1, in <module> NameError: name 'x' is not defined Here is the way, you could define the variable without defining/assigning the value >>> x=None >>> x
