The type of software-generated problems that can indicate that a software bug is causing a memory error are page fault, exception error and general-protection fault. Registry errors show that there are parts of the registry that were written to the faulty parts of the RAM. An erroneous memory count would happen when there is incompatibility in the installation.
Answer:
\n
Explanation:
readline() method is used to read one line from a file. It returns that line from the file.
This line from the file is returned as a string. This string contains a \n at the end which is called a new line character.
So the readline method reads text until an end of line symbol is encountered, and this end of line character is represented by \n.
For example if the file "abc.txt" contains the lines:
Welcome to abc file.
This file is for demonstrating how read line works.
Consider the following code:
f = open("abc.txt", "r") #opens the file in read mode
print(f.readline()) # read one line from file and displays it
The output is:
Welcome to abc file.
The readline() method reads one line and the print method displays that line.
The below displays ice-creams with its associated flavours. This we would display using <UL>
• Stick
o Chocobar
o Feast
• Bowl
o Butterscotch
o Blueberry
<UL>
<LI>Stick
<UL>
<LI>Chocobar </LI>
<LI> feast</LI>
</UL>
</LI>
<LI>Bowl
<UL>
<LI> Butterscotch </LI>
<LI> Blueberry </LI>
</UL>
</LI>
</UL>
Here <UL> tag is used to create un ordered list and one another <UL> tag inside <LI> created nested list which is the actual requirement. Like this we can created nested unordered lists and you can nest upto 4 levels and increasing the number of levels further may reduce clarity.
Answer:
The solution code is written in Python:
- def square(num):
- if type(num).__name__ == 'int':
- sq_num = num * num
- return sq_num
- else:
- return "Invalid input"
-
- print(square(5))
- print(square("Test"))
Explanation:
To ensure only certain type of operation can be applied on a input value, we can check the data type of the input value. For example, we define a function and name it as <em>square</em> which take one input number, <em>num </em>(Line 1).
Before the <em>num</em> can be squared, it goes through a validation mechanism in by setting an if condition (Line 2) to check if the data type of the input number is an integer,<em> int.</em> If so, the<em> num </em>will only be squared otherwise it return an error message (Line 6).
We can test our function by passing value of 5 and "Test" string. We will get program output:
25
Invalid input
