Answer:
c. Using the Data Refinery tool
Explanation:
Data wrangling and tidying in Data Science is the process whereby data to be analysed is obtained, cleaned and arranged before it is analysed in the environment.
Since Watson Studio happens to be an IBM premier integrated development environment for data science and artificial intelligence practitioners, there is need for them to have data softwares to make data scientists practitioners' works easier.
<em>In this scenario, the best tools to aid in tidying data in the Watson studio would be the use of </em><u><em>Data Refinery Tool.</em></u>
Answer:
4. Command line interface (CLI)
Explanation:
An operating system is a system software pre-installed on a computing device to manage or control software application, computer hardware and user processes.
This ultimately implies that, an operating system acts as an interface or intermediary between the computer end user and the hardware portion of the computer system (computer hardware) in the processing and execution of instructions.
Some examples of an operating system on computers are QNX, Linux, OpenVMS, MacOS, Microsoft windows, IBM, Solaris, VM etc.
A Command line interface (CLI) refers to a text-based user interface that allow users to operate a software application or program, as well as manage and execute operating system functions by typing standard line of commands into the text-based user interface with a real-time response.
Basically, the CLI is solely text-based and as such requires a thorough knowledge and understanding of global commands, as well as administrative privileges in some cases.
<em>Hence, the operating system function which has a steeper learning curve (more difficult to learn) and can potentially break the system without careful use of its operations is the Command line interface (CLI). </em>
Answer:
Explanation:
The internet could be regarded has a marketplace or platform which gives individuals, businesses the opportunity to interact, relate, access opportunities, learn in an easy manner with the help of a data connection. The internet has redefined the process and concept of acesing information and interaction with the ease and coverage it brings. The Social media is could be seen a part of the internet platform which allows people to relate and interact, make friends, promote brands and so on. The internet and social media platforms however, in spite of its huge benefits comes with its inherent risk. Including the surge in cyber crime, immorality and information theft to mention a few. Common scenarios whereby banking details are being stolen from databases resulting in wholesale illegal transfer of funds. Issues of blackmail and violent defamation by groups of cohorts has also been a con in the advent of internet and social media, including growing trends of fake news which usually escalate tension, in which the recent unrest in my vicinity benefitted negatively from.
Answer:
#program in Python
#read until user Enter an integer
while True:
#try block to check integer
try:
#read input from user
inp = int(input("Enter an integer: "))
#print input
print("The integer is: ",inp)
break
#if input is not integer
except ValueError:
#print message
print("Wrong: try again.")
Explanation:
In try block, read input from user.If the input is not integer the print a message in except block.Read the input until user enter an integer. When user enter an integer then print the integer and break the loop.
Output:
Enter an integer: acs
Wrong: try again.
Enter an integer: 4a
Wrong: try again.
Enter an integer: 2.2
Wrong: try again.
Enter an integer: 12
The integer is: 12
Hacking would be a widespread problem.
