Exit () and Quit () Function in Python 3

-
Exit and Quit both are used to get out of a program which is running.

he exit and quit "functions" are actually site.Quitter objects and are loaded, at interpreter start up, from site.py. However, if the interpreter is started with the -S flag, or a custom site.py is used then exit and quit may not be present.
Recommendation
Replace uses of exit() and quit() with sys.exit() which is built into the interpreter and is guaranteed to be present.
Example
In this example, exit() is used and will fail if the interpreter is passed the -S option.

def main():
    try:
        process()
    except Exception as ex:
        print(ex)
        exit(1)
In this example, sys.exit() is used and will behave the same regardless of the interpreter options.

Bubble Sort ( C & Python 3)

Bubble Sort Algorithm Bubble Sort   is a simple algorithm which is used to sort a given set of  n   elements provided in form of an array with  n  number of elements. Bubble Sort compares all the element one by one and sort them based on their values. If the given array has to be sorted in ascending order, then bubble sort will start by comparing the first element of the array with the second element, if the first element is greater than the second element, it will  swap   both the elements, and then move on to compare the second and the third element, and so on. If we have tota l   n   elements, then we need to repeat this process for  n-1  times. It is known as  bubble sort , because with every complete iteration the largest element in the given array, bubbles up towards the last place or the highest index, just like a water bubble rises up to the water surface. Sorting takes place by stepping through all the el...

Comparison Logical and Bitwise Operator ( Java Part - 4 )

J ava Comparison Operators Comparison operators are used to compare two values: Operator Name Example Try it == Equal to x == y Try it » != Not equal x != y Try it » > Greater than x > y Try it » < Less than x < y Try it » >= Greater than or equal to x >= y Try it » <= Less than or equal to x <= y Try it » Java Logical Operators Logical operators are used to determine the logic between variables or values: Operator Name Description Example Try it &&  Logical and Returns true if both statements are true x < 5 &&  x < 10 Try it » ||  Logical or Returns true if one of the statements is true x < 5 || x < 4 Try it » ! Logical not Reverse the result, returns false if the result is true !(x < 5 && x < 10) Try it » Java Bitwise Operators Bitwise operators are used to perform binary logic with the bits of an integer or long integer. Operator Description Example Same as Result Decima...

Something about me  H ey peeps, its me Abhishek and it's my first blog ever . I wanted to write something about me, but you know there are people about whom you can write about a trillion lines about their deeds, achievements and there are some people like me, having no achievements and nothing to write about, a single line would be too long I guess lol. Jokes apart, through this blog I will convey and provide all the study materials, which I could gather in my B-tech college life.
