Exception Handling

'''
Exception Handling:
It is the process of responding to unwanted or unexpected events when a computer program runs.
It deals with these events to avoid the program or system crashing.
Without this process, exception would disrupt the normal operation of the program.

Exceptions in Python:
Python has many built-in exceptions that are raised when our program encounters ann error.
When these expections occur, Pythonn interpreter stops the current process and passes it to the calling process until it is handled, otherwise the program will creash.
'''

'''
try....except:
try...except blocks are used in Python to handle errors and exceptions.
The code in try block runs when there is no error.
If the try block catches an error, then the except block is used.
'''

try:
  num = int(input("Enter an integer: "))
except ValueError:
  print("Number entered is not an integer")
# output = 
# Enter an integer: hsjdhs
# Number entered is not an integer

try:
  num = int(input("Enter an integer: "))
  a = [5, 10]
  print(a[num])
except IndexError:
  print("Index Error")
# output =
# Enter an integer: 4
# Index Error

Print Function

#To print something in Python, we write print( ) #print is a function to perform any task. print("Hello World")                                    #output - Hello World #We use double quotes " " to make the object valid and to make it a string. #We can also use single quotes ' ' for the same. print('Hello World')                                      #output = Hello World print(5)                                                         #output - 5 #We didn't use double quote or single quote here as 5 is a number(a valid object) #To print multiple lines in print function, we use triple single or double quotes. print('''Hi How are you?

Sets in Python

''' Python Sets: In Python, a set is an unordered collection of unique elements.  Sets are useful when we need to store a collection of items without any duplicates. Key Characteristics of Sets: 1. Unordered: The items have no defined order, and their position can change. 2. Unique Elements: No duplicate values are allowed. 3. Mutable: Sets can be modified after creation (elements can be added or removed). 4. Heterogeneous: A set can contain elements of different data types. ''' s1 = {1, 2, 3, 4} print(s1)                #output = {1, 2, 3, 4} s2 = {1, 1, 2, 3, 4, 4} print(s2)                #output = {1, 2, 3, 4}   #Duplicates are automatically removed info = {"Sindhu", 24, True, 2002} print(info)              #output = {24, True, 2002, 'Sindhu'}  #Here we can see that the items in set occur in random order, and hence they cannot be accessed using index...
