Typecasting in Python

 '''

Typecasting in Python:

The conversion of data types in Python is known as type casting.


Python supports a wide variety of functions or methods like:

int(), float(), str(), ord(), hex(), oct(), tuple(), set(), list(), dict() etc. for the type casting in Python.

'''


a="1"

b="2"

print(a+b)        #output=12

# We can see the output is 12 because the value of a and b are strings.


print(int(a)+int(b))  #output=3

#We can see the output is 3 because now the values of a and b has become integer functions. 


'''Either two integer functions or two string functions or any two functions of the same data type can be operated to get the result.'''


'''

Two types of typecasting:

1. Explicit Conversion (Explicit typecasting in Python)

2. Implicit Conversion (Implicit typecasting in Python)


Explicit Typecasting:

The conversion of one data type into another data type, done via developer or programmer's intervention or manually as per the requirement, is known as explicit type conversion.

It can be done by using the int(), float(), hex(), oct(), str() etc. functions.


Implicit Typecasting:

Data types in Python do not have the same level i.e. ordering of data types is not the same in Python. Some of the data types have higher-order, and some have lower order. While performing any operation on variables with different data types in Python, one of the variable's data types will be changed to the higher data type. According to the level, one data type is converted into other by the Python interpreter itself (automatically). This is called implicit data type.

'''


#Explicit-Hum kar rahe hein

#Implicit- Python khud kar raha hai


#Example of Explicit Typecasting:

# string="15"

# number=7

# string_number=int(string) i.e. int(15)=15


'''It throws an error if the string is not a valid integer

i.e. there will be a syntax error if we add "15"+7 

'''


#Sum= 15+7=22

#print("The sum of both the numbers is: ",sum)


#Example of Implicit Typecasting:

a=1.9

b=9

print(a + b)        #output=10.9

print("The type of (a+b) is", type (a+b))   #output=10.9 <class 'float'>

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? I am good, Thank you''' print(...

Arithmetic Operators

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...
