replit has continuously improved its platform, and the release of python 3.13 brought several exciting features and enhancements. here’s a tutorial that highlights five epic new features of python 3.13, complete with code examples to illustrate their usage.

1. *faster performance improvements*
python 3.13 includes numerous performance enhancements that make it faster than previous versions, especially in common tasks like function calls and memory management.

*example:*
```python
import time

measure performance
start_time = time.time()

a simple function to demonstrate performance
def compute_sum(n):
return sum(range(n))

result = compute_sum(1000000)
end_time = time.time()

print(f"result: {result} | time taken: {end_time - start_time:.6f} seconds")
```

2. *new syntax features: pattern matching enhancements*
python 3.13 has improved pattern matching capabilities, making it easier to destructure data structures.

*example:*
```python
def process_data(data):
match data:
case (x, y) if x y:
return f"x ({x}) is greater than y ({y})"
case (x, y):
return f"x ({x}) is less than or equal to y ({y})"

print(process_data((5, 3))) output: x (5) is greater than y (3)
print(process_data((2, 4))) output: x (2) is less than or equal to y (4)
```

3. *type hinting improvements*
python 3.13 introduces better support for type hints, including the ability to use `self` in class methods for a cleaner and more intuitive type hinting.

*example:*
```python
from typing import self

class builder:
def __init__(self, value: int):
self.value = value

def add(self, amount: int) - self:
self.value += amount
return self

builder = builder(0).add(10).add(5)
print(builder.value) output: 15
```

4. *new standard library modules*
python 3.13 comes with new standard library modules that enhance the functionality of the language. one notable addition is the `tomllib` module, which allows ...
