Stacks and queues are data structures that manage data in different orders: LIFO for stacks and FIFO for queues.

• Stack: Last In, First Out (LIFO) - Think of a stack of plates; you add and remove plates from the top.

• Queue: First In, First Out (FIFO) - Like a line at a coffee shop; the first person in line is the first to be served.

• Real-life stack example: A stack of books where you can only take the top book.

A palindrome is a string that reads the same forwards and backwards. This function checks for that property.

• A string is a palindrome if it is identical when reversed.

• Example: 'radar' is a palindrome, while 'hello' is not.

• To check, compare the string with its reverse using slicing: s == s[::-1].

• Consider case sensitivity and spaces: 'A man a plan a canal Panama' is a palindrome if spaces and cases are ignored.

Key Python libraries for data analysis include NumPy, Pandas, Matplotlib, and SciPy, each serving unique analytical purposes.

• NumPy: Provides support for large, multi-dimensional arrays and matrices, along with a collection of mathematical functions. Example: np.array([1, 2, 3])

• Pandas: Offers data structures like DataFrames for data manipulation and analysis. Example: pd.DataFrame({'A': [1, 2], 'B': [3, 4]})

• Matplotlib: ...read more
