In Python, sometimes we need to convert one data type into another.
This process is called Type Casting or Type Conversion.
For example, converting a number into a string or a string into a number.
🔹 What is Type Casting?
Type casting means converting one data type into another using built-in functions.
Example:
x = 10 y = str(x) print(y) print(type(y))
Output:
10 <class 'str'>
🔹 Common Type Casting Functions
1. int() → Converts to Integer
x = "20" y = int(x) print(y) print(type(y))
2. float() → Converts to Float
x = "10.5" y = float(x) print(y)
3. str() → Converts to String
x = 100 y = str(x) print(y)
🔹 Real-Life Example
Suppose you take input from a user. By default, input is always a string.
age = input("Enter your age: ")
age = int(age)
print(age + 5)
Without conversion, Python will give an error when adding numbers.
🔹 Important Note
Not all conversions are possible.
x = "hello" y = int(x) # ❌ Error
Always ensure the value is compatible before converting.
🔹 Why Type Casting is Important?
- Helps in calculations
- Prevents errors
- Makes data usable in different formats
✅ Conclusion
Type casting allows you to convert data into the required format. It is a very important concept when working with user input and calculations.
