Type Conversion's

Type Conversion :

String Slicing :

Obtaining a part of a string is called string slicing.

Code :
variable name[start index is to end index]

* Start from the start index and stops at end index
* End index is not included in the slice.

Code :
message = "Hi Ravi"
part = message[3:7]
print(part)

Output :
Ravi

Slicing to End : If end index is not specified, slicing stops at the end of the string.

Code :
message = "Hi Ravi"
part = message[3:]
print(part)

Output :
Ravi

Slicing from Start : If start index is not specified, slicing starts from the index 0.

Code :
message = "Hi Ravi"
part = message[:2]
print(part)

Output :
Hi

Checking Data Type : Check the datatype of the variable or value using type()

Printing Data Type :

Code :
print(type(10))
print(type(4.2))
print(type("Hi"))

Output :
class 'int,
class 'float'
class 'str

Type Conversion : Converting the value of one data type to another data type is called Type Conversion or Type Casting.
We can convert :

String to Integer ,
Integer to Float ,
Float to String and so on.
String to Integer
int() converts valid data of any type to integer

Code :
a = "5"
a = int(a)
print(type(a))
print(a)

Output :
class 'int'
5

Invalid Integer Conversion :

Code :
a = "Five"
a = int(a)
print(type(a))

Output :
ValueError:
invalid literal for int() with base

Code :
a = "5.0"
a = int(a)
print(type(a))

Output :
invalid literal for int() with base 10

Adding Two Numbers :

Code :
a = input()
a = int(a)
b = input()
b = int(b)
result = a + b
print(result)

Input :
2
3

Output :
5

Integer to String : str() converts data of any type to a string.

Code :
a = input()
a = int(a)
b = input()
b = int(b)
result = a + b
print("Sum: " + str(result))

Input :
2
3

Output :

Sum: 5

Summary
1. int() -Converts to integer data type
2. float() - Converts to float data type
3. str() - Converts to string data type
4. bool() - Converts to boolean data type
