## Beginner's Approach: Finding the Factorial of a Number

*Learn how a beginner programmer would approach finding the factorial of a number.*

A beginner programmer would typically use a straightforward approach to find the factorial of a number. They would use a `for`

loop to iterate through the numbers and calculate the factorial.

Here's an example of how a beginner programmer might write the code:

```
n = int(input("Enter a number to find its factorial: "))
factorial = 1
if n < 0:
print("Factorial does not exist for negative numbers")
elif n == 0:
print("The factorial of 0 is 1")
else:
for i in range(1, n + 1):
factorial *= i
print(f"The factorial of {n} is {factorial}")
```

## Intermediate's Approach: Finding the Factorial of a Number

*Discover how an intermediate programmer would approach finding the factorial of a number.*

An intermediate programmer would typically use a more advanced approach to find the factorial of a number. They would use a function for better code structure and readability, and may also utilize the `math`

library for basic checks.

Here's an example of how an intermediate programmer might write the code:

```
import math
def factorial(n):
if n < 0:
return "Factorial does not exist for negative numbers"
elif n == 0:
return 1
else:
return math.prod(range(1, n + 1))
n = int(input("Enter a number to find its factorial: "))
result = factorial(n)
print(f"The factorial of {n} is {result}")
```

## Expert's Approach: Finding the Factorial of a Number

*Explore how an expert programmer would approach finding the factorial of a number.*

An expert programmer would typically use an optimized approach to find the factorial of a number. They might utilize recursion for elegance, add type hints for better maintainability, and use Python's conditional expression for conciseness.

Here's an example of how an expert programmer might write the code:

```
from typing import Union
def factorial(n: int) -> Union[int, str]:
return 1 if n == 0 else n * factorial(n - 1) if n > 0 else "Factorial does not exist for negative numbers"
n = int(input("Enter a number to find its factorial: "))
print(f"The factorial of {n} is {factorial(n)}")
```

## Beginner's Approach: Generating Fibonacci Numbers

*Learn how a beginner programmer would generate Fibonacci numbers.*

A beginner programmer would typically use a basic `for`

loop and a list to generate Fibonacci numbers.

Here's an example of how a beginner programmer might write the code:

```
n = int(input("How many Fibonacci numbers to generate? "))
fibonacci_sequence = []
if n <= 0:
print("Please enter a positive integer.")
elif n == 1:
print([0])
else:
fibonacci_sequence = [0, 1]
for i in range(2, n):
next_number = fibonacci_sequence[-1] + fibonacci_sequence[-2]
fibonacci_sequence.append(next_number)
print(fibonacci_sequence)
```

## Intermediate's Approach: Generating Fibonacci Numbers

*Discover how an intermediate programmer would generate Fibonacci numbers.*

An intermediate programmer would typically use list comprehensions and the `zip`

function to generate Fibonacci numbers in a more Pythonic way.

Here's an example of how an intermediate programmer might write the code:

```
n = int(input("How many Fibonacci numbers to generate? "))
if n <= 0:
print("Please enter a positive integer.")
else:
fibonacci_sequence = [0, 1]
[fibonacci_sequence.append(fibonacci_sequence[-1] + fibonacci_sequence[-2]) for _ in range(n - 2)]
print(fibonacci_sequence[:n])
```

## Expert's Approach: Generating Fibonacci Numbers

*Explore how an expert programmer would generate Fibonacci numbers.*

An expert programmer would typically use generators for a more memory-efficient approach to generate Fibonacci numbers. They might also utilize Python's unpacking feature for elegant variable swapping.

Here's an example of how an expert programmer might write the code:

```
def generate_fibonacci(n: int):
a, b = 0, 1
for _ in range(n):
yield a
a, b = b, a + b
n = int(input("How many Fibonacci numbers to generate? "))
if n <= 0:
print("Please enter a positive integer.")
else:
print(list(generate_fibonacci(n)))
```

## The Benefits of Becoming a Proficient Programmer
