You can "update" an existing string by (re)assigning a variable to another string. The new value can be related to its previous value or to a completely different string altogether. For example −Example Live Demo#!/usr/bin/python var1 = 'Hello World!' print "Updated String :- ", var1[:6] + 'Python'OutputWhen the above code is executed, it produces the following result −Updated String :- Hello Python
With the help of following MySQL query, we can get the first day of the current month −mysql> SELECT DATE_SUB(LAST_DAY(NOW()),INTERVAL DAY(LAST_DAY(NOW()))- 1 DAY) AS 'FIRST DAY OF CURRENT MONTH'; +----------------------------+ | FIRST DAY OF CURRENT MONTH | +----------------------------+ | 2017-10-01 | +----------------------------+ 1 row in set (0.00 sec)

For example − Live Demo#!/usr/bin/python var1 = 'Hello World!' var2 = "Python Programming" print "var1[0]: ", var1[0] print "var2[1:5]: ", var2[1:5]OutputWhen the above code is executed, it produces the following result −var1[0]: H var2[1:5]: ytho
