It is a general thumb rule that though you can catch all exceptions using code like below, you shouldn’t:try: #do_something() except: print "Exception Caught!"However, this will also catch exceptions like KeyboardInterrupt we may not be interested in. Unless you re-raise the exception right away – we will not be able to catch the exceptions:try: f = open('file.txt') s = f.readline() i = int(s.strip()) except IOError as (errno, strerror): print "I/O error({0}): {1}".format(errno, strerror) except ValueError: print "Could not convert data to an integer." except: ...

The HTML onload event attribute is triggered when an object has been loaded in an HTML document.SyntaxFollowing is the syntax −Let us see an example of HTML onload event Attribute−Example Live Demo body { color: #000; height: 100vh; background-color: #FBAB7E; background-image: linear-gradient(62deg, #FBAB7E 0%, #F7CE68 100%); text-align: center; padding: 20px; } function get() { alert("Hi! you just refresh the document."); } HTML onload Event Attribute Demo Now try to refresh this document. OutputNow try to reload the document to observe how onload event attribute works.
Only a single except clause in a try block is invoked. If you want the exception to be caught higher up then you will need to use nested try blocks.Let us write 2 try...except blocks like this:try: try: 1/0 except ArithmeticError as e: if str(e) == "Zero division": print ("thumbs up") else: raise except Exception as err: print ("thumbs down") raise errwe get the following outputthumbs down Traceback (most recent call last): File "C:/Users/TutorialsPoint1/~.py", line 11, in raise err File "C:/Users/TutorialsPoint1/~.py", line 3, in 1/0 ZeroDivisionError: division by zeroAs per python tutorial there is one and only one ...

The HTML onbeforeprint event attribute is triggered when a page is about to be printed or before the print dialog box appears in the HTML document.SyntaxFollowing is the syntax −Let us see an example of HTML onbeforeprint event Attribute−Example Live Demo body { color: #000; height: 100vh; background-color: #FBAB7E; background-image: linear-gradient(62deg, #FBAB7E 0%, #F7CE68 100%); text-align: center; padding: 20px; } p { font-size: 1.1rem; } HTML onbeforeprint Event Attribute Demo ...

The HTML onafterprint event attribute is triggered when a page has started printing or if the print dialog box has been closed in the HTML document.SyntaxFollowing is the syntax −Let us see an example of HTML onafterprint event Attribute−Example Live Demo body { color: #000; height: 100vh; background-color: #FBAB7E; background-image: linear-gradient(62deg, #FBAB7E 0%, #F7CE68 100%); text-align: center; padding: 20px; } p { font-size: 1.1rem; } HTML onafterprint Event Attribute Demo ...

The HTML form method attribute defines how to send form-data that means to be sent as URL variable or to be sent as an HTTP post transaction.SyntaxFollowing is the syntax −Here get sends the form data as URL variable and post sends the form data as an HTTP post transaction.Let us see an example of HTML Form method Attribute−Example Live Demo body { color: #000; height: 100vh; background: linear-gradient(62deg, #FBAB7E 0%, #F7CE68 100%) no-repeat; text-align: center; } input { width: 315px; ...

The HTML Location assign() method loads a new HTML document without replacing the URL of the current HTML document from the document history.SyntaxFollowing is the syntax −location.assign(URL)Let us see an example of HTML Location assign() Method−Example Live Demo body { color: #000; height: 100vh; background: linear-gradient(62deg, #FBAB7E 0%, #F7CE68 100%) no-repeat; text-align: center; } .btn { background: #db133a; border: none; height: 2rem; border-radius: 20px; width: 330px; ...

In this article, we will learn about the solution and approach to solve the given problem statement.Problem statementGiven the starting and ending range of an interval. We need to print all the numbers in the interval given.A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself.There are two for loops, first for loop is for getting the numbers in the interval and second loop for the checking whether the number is prime or not.Now let’s see the implementation.Example Live Demostart = 10 end = 29 for val in range(start, end + ...

We have a number N and a base b. In this program we have to check whether the number is starting with 1 in base b or not. Suppose a number 6 is given. In binary this is 110, so it starts with 1, in base 4 also it will be 124. Here also it starts with 1.As we know, if a number N is represented in base b, b gets converted to m+1 bit sequence bm bm-1 … b0. This implies bm bm + bm-1 * bm-1 + … + b0*b0 = N. The largest number will be 2*bm ... Read More
In this section we will see how to check whether a number is Palindrome or not using the PL/SQL. In PL/SQL code, some group of commands are arranged within a block of related declaration of statements.A number is palindrome if the number, and the reverse of that number are same. Suppose a number 12321, this is palindrome, but 12345 is not a palindrome.ExampleDECLARE n number; m number; temp number:=0; rem number; BEGIN n :=12321; m :=n; while n>0 loop rem := mod(n, 10); temp := (temp*10)+rem; ...
