Answer:
Ctrl+Space is the keyboard shortcut to select an entire column.
Explanation:
When you press the Shift+Space shortcut the first time it will select the entire row within the Table. Press Shift+Space a second time and it will select the entire row in the worksheet.
The same works for columns. Ctrl+Space will select the column of data in the Table. Pressing the keyboard shortcut a second time will include the column header of the Table in the selection. Pressing Ctrl+Space a third time will select the entire column in the worksheet.
You can select multiple rows or columns by holding Shift and pressing the Arrow Keys multiple times.
Answer:
- from matplotlib import pyplot as plt
-
- with open("text.txt") as file:
- data = file.readlines()
- category = []
- amount = []
- for row in data:
- values = row.split(" ")
- category.append(values[0])
- amount.append(float(values[1]))
-
- figure = plt.figure()
- ax = figure.add_axes([0,0,1,1])
- ax.axis('equal')
- ax.pie(amount, labels = category, autopct='%1.2f%%')
- plt.show()
Explanation:
Firstly, we need to import matplotlib library (Line 1).
Next, open a file stream and use readlines method to read the data from the text file (Line 4). Presume the data read from the text files are as follows:
Rent 450
Gas 150
Food 500
Clothing 120
Car 600
Create two lists, category and amount (Line 5-6). Use a for loop to traverse through the read data and use split method to break each row of data into two individual items. The first item is added to category list whereas the second item is added to amount list (Line 7 - 10).
Next, create a plot figure and then add the axes (Line 12 - 13). We can use the pie method to generate a pie chart (Line 15) by setting the amount list as first argument and category list as value of labels attributes. The output pie chart can be found in the attachment.
Answer:
Option d is the correct answer for the above question.
Explanation:
- Authentication is a process that enables the user to enter the system. This process helps to secure the data. It is because with the help of this only valid users can enter the system. In this process, the system asks some unique information from the user which can only be known to the valid user.
- Some systems put two types of authentications one is some information about the valid user and the other is a fingerprint scan that takes the data of the user finger and matches with their user name and password. If it matches then only he can enter into the system.
- The above question asks about the mechanism which is used for multifactor authentication. This authentication is known as a fingerprint scan. So the option D is the correct answer while the other is not because:-
- Option 'a' states about the username which is used in the first authentication.
- Option b states about pin which can be used in the place of username.
- Option c states about the security question which is used when the user forgets the password.
