Multi-line comments show up in more than one line. Every one of the lines to be commented is to be prefixed by a #. You can likewise an excellent easy route technique to comment on different lines. You should simply hold the Ctrl key and left snap in each spot any place you need to incorporate a # character and type a # just once. This will comment on each line where you presented your cursor.

Django Python

Ques:- Explain different ways to trigger / raise exceptions in your python script ?

Asked In :- Fluid AI, Surya Software, Intelizign, RELX Group, GyanMatrix Technologies, Interview Mocha, Lexicon Networks, Onebill software, Kriti, Volksoft Technologies,

Right Answer:
In Python, you can trigger or raise exceptions using the following methods:

1. **Using the `raise` statement**: You can raise a specific exception by using `raise ExceptionType("Error message")`.

2. **Raising a built-in exception**: You can raise built-in exceptions like `ValueError`, `TypeError`, etc., directly with `raise ValueError("Invalid value")`.

3. **Using `raise` without arguments**: This re-raises the last exception caught in an `except` block.

4. **Custom exceptions**: You can define your own exception class and raise it using `raise MyCustomException("Error message")`.

5. **Using `assert` statement**: This raises an `AssertionError` if the condition is false, e.g., `assert condition, "Error message"`.

6. **Using `sys.exit()`**: This raises a `SystemExit` exception to terminate the program.

The global interpreter lock is used to allow the running of the thread one at a time. This is internal to the program only and used to distribute the functionality along all the virtual machines that are used. Python allows the switching between the threads to be performed by using the byte code instructions that are used to provide platform-independence. The sys.setcheckinterval() method is used that allow the switching to occur during the implementation of the program and the instruction. This provides the understanding in the field of accounting to use the byte code implementation that makes it portable to use. The atomicity can be provided such that the shared variables can be given as built-in data types.

Django Python

Ques:- How to make Foreign Key relation in django ?

Asked In :- Mundrisoft Solutions LLP, Surya Software, Vector India, Testrig Technologies, Ojas Innovative Technologies, BluePi, Heptagon Technologies, Propellum Infotech, Signals & Systems (India), Synture,

Right Answer:
To create a Foreign Key relation in Django, use the `ForeignKey` field in your model. For example:

```python
from django.db import models

class Author(models.Model):
name = models.CharField(max_length=100)

class Book(models.Model):
title = models.CharField(max_length=100)
author = models.ForeignKey(Author, on_delete=models.CASCADE)
```

In this example, the `Book` model has a Foreign Key relation to the `Author` model.

Data Warehouse Developer SQL Server

Ques:- What are DTS subroutines? What is their use and How do you write them?

Asked In :- D-Mart, Cavisson Systems, Eidiko Systems Integrators, Knot Solutions, Utthunga, TechnoGen, Fastlab, CodeQuotient, Access Healthcare, TietoEVRY,

Right Answer:
DTS (Data Transformation Services) subroutines are reusable blocks of code that can be called from within a DTS package to perform specific tasks or operations. They are used to encapsulate logic that can be reused across multiple packages, improving maintainability and reducing redundancy.

To write a DTS subroutine, you typically use VBScript or JScript. You define the subroutine in the "Global Variables" section of the DTS package, and it can be called from tasks or other subroutines within the package. Here's a simple example in VBScript:

```vbscript
Function MySubroutine()
' Your code here
MsgBox "Hello from MySubroutine!"
End Function
```

You can call this subroutine from a task by using the following syntax:

```vbscript
Call MySubroutine()
```
