Python Programming

A database is a program that stores information. Such info can be sorted and retrieved in whatever output the operator requires. A common use for a database is to store the names and addresses of members belonging to a club, etc. The club Secretary or Treasurer can sort the membership database to show those member who have not yet renewed their membership subscription.

A commercial company may have a database showing customers' names, addresses and other details, their past purchases, their credit state, and so on.

Visual basic is a proprietary programming language written by Microsoft, so programs written in Visual basic cannot, easily, be transferred to other operating systems. There are versions of Basic that run on several operating systems, but they aren't direct clones of VB so some work would have to be done. Visual Basic is built around the .NET environment used by all Microsoft Visual languages, so there is very little that can't be done in Visual Basic that can be done in other languages (such as C#). Visual Basic only really exists as a high-level Windows programming language - for writing Windows applications. Whereas other languages (particularly the "C" family of C, C++ and C#) have a life outside of Windows and are used for everything from writing device drivers or "embedded" systems up to large applications. There are some, fairly minor disadvantages compared with C: C has better declaration of arrays - its possible to initialise an array of structures in C at declaration time; this is impossible in VB. in combination if tests: if A and B then endif In C, it is defined that A is evaluated first, then B. Visual Basic doesn't guarantee the order of evaluation; this makes some programming a bit more awkward; in C, the following is safe: if Inst>0 and Array(inst) =5 then

{

// do stuff

} as the Inst>0 test is always done first, in visual basic it becomes: if Inst > 0

if Array(inst) = 5 then

' do stuff

endif

endif The advantages of VB are the ease of learning - the syntax is simpler than other languages (although it can be argued that C has more flexibility). The visual environment is excellent (although that's common to all the visual languages). It's widely used and, therefore, well understood.

it depends what type of program you wish to write. python is a very simple programing langauge therefore it doesnt have much room to play with. i mainly use it to work out simple math problems, or use it to calculate thing for games i play,

Ex.) This is a program i wrote to work out the Pythagorean therom to find side "C":

a = input("Enter Corner Side A\n ")

b = input("Enter Corner Side B\n ")

c = a*a+b*b

import math

print math.sqrt(c)

raw_input("Press <enter> To Leave Program")

input mean that's where you enter your variable, raw input is what you put at the end so it doesnt just run away (NOTE*** THIS IS A PYTHON 2.6.5 SCRIPT, IT WILL NOT WORK ON OTHER VERSIONS OF PYTHON"

notice i put ("Press <enter> To Leave Program") this is what it will say before it "runs away". i suggest watching some youtube videos on how to write programs for your version of python. also try using the manual that comes with your version of python. it helps greatly.

Programmers use pseudo-code to debug programs. Pseudo-code lays out the basic coding for the program before putting it into any specific programming language. That way, a programmer can be sure that all the necessary components are included, and that the program will run as expected.

Functions hold code, which means anything that happens within a function can be "called" later on. Allowing the programmer to save time, and ensuring he doesn't have to re-write code. Example:

Instead of writing "Hello" 10 times, I made a function that said print("hello") 5 times, then "Called" the function twice.

def helloFiveTimes():

print("Hello")

print("Hello")

print("Hello")

print("Hello")

print("Hello")

return

helloFiveTimes()

helloFiveTimes()

There are three forms of loop commonly used in C/C++, the for loop, the while loop

and the do-while loop.

The for loop is most commonly used whenever an action is going to be performed a set amount of times. For example, to sum every element in an array:

for(i = 0; i < arraySize; i++)

{

sum = sum + array[i];

}

The while loop and do-while loop are commonly used to loop until a condition is met. The difference between the two is that the do-while loop goes through one iteration before checking its condition, while the while loop checks its condition before any execution of the loop.

Example do-while loop:

do

{

randomNumber = rand() % 10;

}while(randomNumber != 6);

Example while loop:

cout > number;

while(number < 0)

{

cout > number;

}

It means that python will print(or write out) a value you input.

Hey sunil i have an idea about mode that is more repeated data is mode ok

na

Example in the series 2,4,5,2,4,5,2,4,24,22,2,2,7,8,9,2 Mode for this data is 2 i.e. Answer is 2

One way to do this is to write a function that checks if a number is prime:

def isPrime(number):

for i in range(2, number):

if number%i == 0:

return False

return True

Then create variables to track how many primes have been found and a variable to track which number is being tested for being prime. Increment that variable and test it, and if it is prime print it out (or save it somewhere) and increment the variable being used to track how many primes have been found:

targetPrimes = 10 #number of primes to find

primesFound = 0 #number of primes found

i = 1

while (primesFound < targetPrimes):

i += 1 #first number tested is 2

if isPrime(i):

print(i)

primesFound += 1

Hey, It is not the exact logic for a given program.

Here i m giving the code with minimum number of executing steps.

also i m sure that there doesn't exist any other way to print the same Diamond such that code executing steps will be less than mine.

It is not copied from any website, book etc.

#include

void main()

{

int n,i,s,k,flagReverce=0;

printf("Enter the no. of rows\n");

scanf("%d", &n);

for (i=1; i>=1; i++)

{

for (s=n; s>i; s-)

printf(" ");

for(k=1; k<(i*2)-1; k++)

printf("*")

printf("\n")

if (i == n)

flagReverce = 1

if (flagReverce = 1)

i-=2

}

}

Python is an interpreted, high-level and general-purpose programming language. Python's design philosophy emphasizes code readability with its notable use of significant indentation. Its language constructs and object-oriented approach aim to help programmers write clear, logical code for small and large-scale projects.[29]

Python is dynamically-typed and garbage-collected. It supports multiple programming paradigms, including structured (particularly, procedural), object-oriented and functional programming. Python is often described as a "batteries included" language due to its comprehensive standard library.

In the context of computer programming, Python is an open source programming language.

I put some links that I found helpful when learning Python on my webpage:

you can uninstall it just like any other program.

In this example, I have created an array of numbers called 'foobar', and while the variable 'sum' is less than 20, I will have the program continue to loop back and add the next number in the array sequence.

#!usr/bin/env

foobar = [1, 4, 7, 2, 9, 11, 0, 6, 5, 4, 16, 3]

sum = 0

iteration = 0

while(sum < 20):

sum += foobar[iteration]

iteration += 1

print("Finished!")

The main aim of software developers are to create a website as per the user requirements and need. They create unique database whether for small or large companies. And Coordinate with owner for the website interface. If you are looking for good software developer, Dmitry Khodarenok is serving custom android application development since 7 years.

The only place you can get a legitimate trial of the software Python is from Python's official site. Other downloads may contain virus or other malicious software.

I get in put with input() function like this:

x = input("what do you want to ask")

In Python; the "print" feature will simply output something (defined by you) onto the screen. For example: print("Hello") would output "Hello" to the screen!

A variable falls under the category of "Python identifier". SUch an identifier must start with a letter (uppercase or lowercase) or an underscore, followed by zero or more letters, underscores, and digits. Note that Python is case-sensitive; for example, myvariable, MyVariable, and MYVARIABLE would be treated as three different variables.
