Answer:
Virus scanning technique is the process to scan the software and identify the various viruses in the computing device. The basic aim of virus scanning technique is to provide the information security and review virus in the given program.
The three virus scanning techniques are as follow:
Behavior detection: This type of detection observe the execution of the program and helps in modifying the host file in the system.
Signature based detection: This type of detection uses various type of key aspects for examine the file for creating the fingerprint. It basically represent the byte stream in the file.
Heuristics detection: The basic aim is to detect or examine the files and it is basically designed to improve the security system. It is also known as heur.
In Python, a string is an array of characters, we can access these characters using index operator []. For example, we have a_string = "Hello World" a_string[0] prints the first character in string ('H').
We can also use index operator to make substrings, for example a_string[0:3] will make a substring with first, second, third and fourth character equal to "Hell".
Now to business
my_string = "This is MY string!"
print(my_string[0:7]) # Prints "This is "
print(my_string[0:7:5]) # Prints "T" then prints the sixth character since we start counting at 0 hence prints "Ti" (note that space is also a character).
Hope this helps.
The first two make the most sense.
I hope this helps!
