Ali created a small program in Python that uses NumPy library. He used this library to store his data in a multi-dimensional _______ data structure. This structure allowed him to perform advanced mathematical and scientific calculations in his program.

• panda

• array

• a.     list

In Python, to import the NumPy library as the name "np", we typically code as:

 

import numpy as np

 

Which one of the following would also be valid for importing the NumPy library?

• a.     numpy import as np

• a.     import numpy as npLibrary

• a.     np as import numpy

Ahmed wants to store the sportscar data in the order below in a NumPy array.

 

 

What is the correct syntax?

• a.     import numpy as np sportsCars = np.array(["Ferrari","Porsche","Lamborghini","McLaren"])

• a.     import numpy as np sportsCars = array.np(["Ferrari","Porsche","Lamborghini","McLaren"])

• a.     import numpy as np sportsCars = array(["Ferrari","Porsche","Lamborghini","McLaren"])

What single function should he use to split the array into 5 rows and 3 columns?

• a.     hstack

• a.     transpose

• a.     reshape

• a.     append

• b.     reshape

• a.     vstack

• d.     hstack

• c.     transpose

What single function should she use to change each of the rows to be a column and each column to a row?

• b.     reshape

• a.     vstack

• d.     hstack

• c.     transpose

Noora was given all her school’s library book details in a comma-separated values (csv) file. The file was called library_books.csv , and it contained the title, author, ISBN and date published for each book.

 

To store the data from the file into a Pandas dataframe, what should Noora type?

• import pandas as pd

  df_books = pd.read_csv("library_books.csv")

• import pandas as pd

  df_books = pd.to_csv("library_books.csv")

• df_books = pd.index("library_books.csv")

Ahmed stored the data in a Pandas dataframe called df_results .

 

To print only Lewis Hamilton’s results, like below, what is the correct code?

• print(df_results.loc["Lewis Hamilton"])

• print(df_results.read_csv["Lewis Hamilton"])

• print(df_results.type["Lewis Hamilton"])

• print(df_results.append["Lewis Hamilton"])

Mahmoud created the following flowchart to check whether a number is positive or negative.

 

What type of control structure can be used to program this flowchart in Python?.

• a.     iteration

• a.     selection

• a.     indentation
