Q.Write the statement to get NewDelhi as output using positional index.
[Context: In the textbook, seriesCapCntry = pd.Series(['NewDelhi', 'WashingtonDC', 'London', 'Paris'], index=['India', 'USA', 'UK', 'France']).]

Imagine you have a messy desk with loose notes, receipts, and to-do lists scattered everywhere. Now imagine you take a single strip of paper, write one item on each line in a fixed order, and label the strip "Monday's Expenses." That strip is a Pandas Series — a single column of data with a label for each row.

A Pandas Series is the simplest building block in the Pandas library for Python. It is a one-dimensional array that can hold any type of data — numbers, text, dates, or even mixed types — and it comes with an index, which is like a row number or a custom label for each entry. Think of it as a smart list that remembers the name of each item.

Why does this matter for a commerce or humanities student?

In your work, you will often deal with lists of things: monthly sales figures, student names in a class, dates of transactions, or categories of expenses. A Series lets you store that list in a structured way so you can quickly find, sort, or analyse it. For example, if you have a list of daily footfall in a store, a Series lets you label each day (Monday, Tuesday, …) and then instantly ask: "Which day had the highest footfall?" or "What was the average footfall on weekends?"

How is a Series created?

You can create a Series from several everyday sources:

• From a Python list: You give Pandas a simple list of values, and it automatically assigns numeric indices (0, 1, 2, …) just like the rows in a notebook.
• From a Python dictionary: The dictionary keys become the index labels, and the values become the data. This is very natural — you already think in key-value pairs (e.g., "January": 45000, "February": 52000).
• From a single value: You can create a Series where every entry is the same value, repeated a certain number of times — useful for setting a default or a constant.
• From a NumPy array (if you have done some data science): but for a first meeting, the list and dictionary methods are the most intuitive.
