Type Casting

Type Casting is the process of converting data of one type to another

Python has two types of conversion:

1. Implicit - automatic type conversion
2. Explicit - manual type conversion

Example

int_num = 123
float_num = 1.23
 
new_num = int_num + float_num
 
print("Value:", new_num)
# 124.23
print("Data Type:", type(new_num))
# Data Type: <class 'float'>

smaller data types implicitly get converted to larger data types to avoid loss of data

Python can’t perform implicit conversions on mis-matched data types

can’t add str and int for example: '12' + 23

Explicit Conversions

---

users convert the data type of an object to required data type

you can use built-in functions like int(), float(), str() to perform explicit type conversions

num_string = '12'
num_integer = 23
 
# Type conversion
print(num_integer + int(num_string))
# output: 35
