" for i in range(2, n):\n"
" fib_sequence.append(fib_sequence[-1] + fib_sequence[-2])\n"
" return fib_sequence\n\n"
"# Test the function\n"
"num = 10\n"
"print(f'The first {num} Fibonacci numbers are: {fibonacci(num)}')\n"
"```\n"
"This code generates the first `n` numbers in the Fibonacci series."
),
"if-else": (
"The if-else statement is used for decision-making in Python. It allows the program to execute one block of code if a condition is true, and another block if it is false.\n\n"
"Example:\n"
"```python\n"
"num = 10\n"
"if num % 2 == 0:\n"
" print('Even number')\n"
"else:\n"
" print('Odd number')\n"
"```\n"
"This code checks if a number is even or odd and prints the result."
),
"if else": (
"The if-else statement is used for decision-making in Python. It allows the program to execute one block of code if a condition is true, and another block if it is false.\n\n"

"else:\n"
" print('Odd number')\n"
"```\n"
"This code checks if a number is even or odd and prints the result."
),
"what is shallow copy": (
"A shallow copy creates a new object but references the same nested objects as the original. Changes to nested objects in the copied object will affect the original.\n\n"
"Example:\n"
"```python\n"
"import copy\n"
"original = [[1, 2, 3], [4, 5, 6]]\n"
"shallow = copy.copy(original)\n"
"shallow[0][0] = 100\n"

"print('Shallow:', shallow)\n"
"```\n"
"This code demonstrates how modifying a shallow copy affects the original object's nested elements."
),
"difference between deep and shallow copy": (
"In Python, a shallow copy creates a new object, but nested objects are shared between the copy and the original. "
"A deep copy creates a new object and recursively copies all nested objects, ensuring complete independence.\n\n"
"Example:\n"
"```python\n"
"import copy\n"
"original = [[1, 2], [3, 4]]\n"
"shallow = copy.copy(original)\n"
"deep = copy.deepcopy(original)\n"

"python libraries": (
"Python libraries are collections of pre-written code that simplify tasks. Popular libraries include NumPy (numerical computing), Pandas (data analysis), "
"and Matplotlib (data visualization). Example:\n\n"

"data = {'Name': ['Alice', 'Bob'], 'Age': [25, 30]}\n"
"df = pd.DataFrame(data)\n"
"print(df)\n"
"```\n"
"This creates and displays a simple data table using Pandas."

"Sure! In Python, data types are known as classes. Here are some common data types with examples:\n\n"
"- **Integer (`int`)**:\n"
" ```python\n"
" num = 10\n"
" print(type(num)) # Output: <class 'int'>\n"
" ```\n\n"
"- **String (`str`)**:\n"
" ```python\n"
" text = 'Hello, World!'\n"
" print(type(text)) # Output: <class 'str'>\n"
" ```\n\n"
"- **List (`list`)**:\n"
" ```python\n"
" items = [1, 2, 3]\n"
" print(type(items)) # Output: <class 'list'>\n"
" ```"
),
"for loop": (
"A `for` loop in Python is used to iterate over a sequence and execute a block of code for each item.\n\n"
"Example:\n"
"```python\n"
"fruits = ['apple', 'banana', 'cherry']\n"
"for fruit in fruits:\n"
" print(fruit)\n"
"```\n"

"a = 5\n"
"b = 3\n"
"result = a + b\n"
"print(f'The sum of {a} and {b} is {result}')\n"
"```\n"
"This code adds two numbers and prints the result."
),
"how to read a string": (
"To read a string in Python, you can use the `input()` function. This function takes user input and returns it as a string.\n\n"
"Example:\n"
"```python\n"
"name = input('Enter your name: ')\n"
"print(f'Hello, {name}!')\n"
"```\n"
"This code asks the user to enter their name and then prints a greeting message."
