Correct option is D
The correct syntax for creating a pandas DataFrame is:
pandas.DataFrame(data, index, dtype, copy)
Where:
·
data: The input data (like a list, dictionary, or numpy array) that you want to convert into a DataFrame.
·
index: The index for the rows (optional). If not specified, a default integer index will be used.
·
dtype: The data type to force (optional). This is used to specify the data type for the columns.
·
copy: A boolean that indicates whether to ensure a copy of the data (optional).
Important Key Points:
1.
pandas.DataFrame: This is the constructor used to create a DataFrame from various data structures (list, dictionary, numpy arrays, etc.).
2.
index: The index parameter specifies the labels for rows. It can be a list or range of values.
3.
dtype: This is used to explicitly define the data type of the DataFrame columns.
4.
copy: This ensures that the data is copied, rather than just referencing the original data.
Knowledge Booster:
·
Option (a): This is incorrect because
col is not a valid argument for creating a DataFrame. The correct parameter is
columns if you need to specify column labels.
·
Option (b): This is incorrect because
row is not a valid argument. The correct argument is
index for specifying row labels.
·
Option (c): This is incorrect because
dataFrame should be written as
DataFrame with a capital "D" and "F". Python is case-sensitive, and this is the correct way to call the DataFrame constructor.
