In Python, you can convert one type to another using type casting or conversion functions. Here are some common type conversion techniques:
- Implicit Type Conversion: Python automatically performs implicit type conversion when an operation involves different data types. For example, when you add an integer and a float, Python will convert the integer to a float before performing the addition.
num_int = 5 num_float = 3.14 result = num_int + num_float print(result) # Output: 8.14
- Explicit Type Conversion (Type Casting): You can explicitly convert one type to another using type casting. There are several built-in functions available for type casting in Python:
int(): Converts a value to an integer type.
float(): Converts a value to a floating-point type.
str(): Converts a value to a string type.
bool(): Converts a value to a boolean type.
num_str = "10" num_int = int(num_str) print(num_int) # Output: 10 num_float = float(num_str) print(num_float) # Output: 10.0 bool_str = "True" bool_value = bool(bool_str) print(bool_value) # Output: True
- Custom Type Conversion: You can define your own functions or methods to perform custom type conversion. For example, if you have a specific conversion requirement, you can define a function that handles the conversion logic accordingly.
def convert_to_custom_type(value): # Custom conversion logic # ... return converted_value result = convert_to_custom_type("input")
Remember that not all type conversions are valid or meaningful. Some conversions may result in loss of data or errors if the conversion is not possible. Ensure that the conversion you’re attempting is valid and handles any potential errors or exceptions that may occur during the conversion process.
