I'll restrict my treatment of Unicode strings to the following −Example Live Demo#!/usr/bin/python print u'Hello, world!'OutputWhen the above code is executed, it produces the following result −Hello, world! As you can see, Unicode strings use the prefix u, just as raw strings use the prefix r.

We can store a date with only year value and have zero months as well as zero-days in MySQL table by disabling NO_ZERO_IN_DATE mode. If this mode is enabled then MySQL will count such kind of date as invalid date and stores all zeros.mysql> Insert into year_testing (OrderDate) values('2017:00:00'); Query OK, 1 row affected (0.09 sec) mysql> select * from year_testing; +------------+ | OrderDate | +------------+ | 2017-00-00 | +------------+ 1 row in set (0.00 sec) mysql> SET sql_mode = 'NO_ZERO_IN_DATE'; Query OK, 0 rows affected (0.00 sec) mysql> Insert into year_testing(OrderDate) values('2017:00:00'); Query OK, 1 row ...

MySQL permits to declare a column YEAR type, with the help of which we can store year values in that column.mysql> Create table year1 (Year_Copyright YEAR); Query OK, 0 rows affected (0.21 sec) mysql> Insert into year1(Year_Copyright) values (2017); Query OK, 1 row affected (0.08 sec) mysql> Select * from year1; +----------------+ | Year_Copyright | +----------------+ | 2017 | +----------------+ 1 row in set (0.00 sec)
It can be done by using either CURDATE() or NOW() in MySQL query as follows −mysql> Insert into year1(Year_Copyright) values (CURDATE()); Query OK, 1 row affected, 1 warning (0.06 sec) mysql> Select * from year1; +----------------+ | Year_Copyright | +----------------+ | 2017 | | 2017 | +----------------+ 2 rows in set (0.00 sec) mysql> Insert into year1(Year_Copyright) values (NOW()); Query OK, 1 row affected, 1 warning (0.06 sec) mysql> Select * from year1; +----------------+ | Year_Copyright | +----------------+ | 2017 | | 2017 | | 2017 | +----------------+ 1 rows in set (0.00 sec)

NEWLINEs within the string, whether explicitly given like this within the brackets [ ], or just a NEWLINE within the variable assignment will also show up.
