1In Python Pandas, which library is typically imported using the alias `pd` when working with Series and DataFrames?
A.NumPy
B.Pandas
C.Matplotlib
D.SciPy
Explanation: The conventional import is `import pandas as pd`. Pandas provides the Series and DataFrame structures used for Class 12 IP data handling.
2A Pandas Series is best described as which of the following?
A.A two-dimensional labelled table of data
B.A one-dimensional labelled array capable of holding any data type
C.A pure Python list without labels
D.A database table stored only on disk
Explanation: A Series is a 1-D labelled array. Labels form its index; values may be numbers, strings, or other types.
3Which statement correctly creates a Pandas Series from a Python list of marks?
A.s = pd.Series([78, 85, 90])
B.s = pd.DataFrame([78, 85, 90])
C.s = series([78, 85, 90])
D.s = pd.list([78, 85, 90])
Explanation: `pd.Series([...])` constructs a Series. Default integer index 0,1,2 is assigned unless you pass `index=`.
4What does the `index` parameter control when creating a Pandas Series?
A.The data type of each value only
B.The labels associated with each element
C.The number of columns in a Series
D.Whether the Series is stored as CSV
Explanation: The `index` argument supplies custom labels for each value (e.g., student names or dates).
5A Pandas DataFrame is best described as:
A.A single labelled scalar value
B.A one-dimensional array only
C.A two-dimensional labelled data structure with rows and columns
D.An unsorted set of unique keys
Explanation: A DataFrame is a 2-D table-like structure with labelled axes (rows = index, columns = column labels).
6Which method is commonly used to display the first few rows of a DataFrame `df`?
A.df.tail()
B.df.head()
C.df.first()
D.df.top()
Explanation: `df.head(n)` returns the first n rows (default 5). It is standard for quick inspection.
7What does `df.shape` return for a DataFrame?
A.Only the number of columns
B.Only the number of rows
C.A tuple (number of rows, number of columns)
D.The memory address of the DataFrame
Explanation: `df.shape` returns `(nrows, ncols)`, which is essential for understanding table size.
8Which attribute lists the column labels of a DataFrame `df`?
A.df.rows
B.df.index
C.df.columns
D.df.labels
Explanation: `df.columns` holds the column Index (labels). `df.index` holds the row labels.
9To read a CSV file named `marks.csv` into a DataFrame, which call is correct?
A.pd.read_csv('marks.csv')
B.pd.read_excel('marks.csv')
C.pd.open_csv('marks.csv')
D.pd.load('marks.csv')
Explanation: `pd.read_csv(path)` loads delimited text into a DataFrame. CSV is the most common exam import format.
10Given Series `s` with values [10, 20, 30], what does `s * 2` produce?
A.A Series with values [12, 22, 32]
B.A Series with values [20, 40, 60]
C.An error because Series cannot be multiplied
D.A DataFrame with two columns
Explanation: Arithmetic on Series is element-wise (vectorised). Each value is multiplied by 2.
