Basic operations:
Click on the cell to select it.
Press SHIFT+ENTER on your keyboard or press the play button (<button class='btn btn-default fa-step-forward fa'><span class="toolbar-btn-label">Run</span></button>) in the toolbar above.
Open new cells using the plus button (<button class='btn btn-default fa-plus fa' title="Run"></button>)
Let's us print a Hello World! statement
Write
python
print("Hello World!") 
into the cell below:
Press SHIFT+ENTER on your keyboard!
Hello World! in other language
Fortran
fortran
    PROGRAM HELLO
    WRITE (*,100)
    STOP
100 FORMAT (' Hello World! ' /)
    END
Lisp
lisp
(print "Hello World!")
C++
```cpp
include <iostream.h>
main()
{
    cout << "Hello World!" << endl;
    return 0;
}
```
Java
java
class HelloWorld {
  static public void main( String args[] ) {
    System.out.println( "Hello World!" );
  }
}
Matlab
octave
disp('Hello World!');
JavaScript
javascript
document.write('Hello World!')
Screen Output
To enter more than one line in a cell, press Enter. The print function will print all the objects seprated by a comma , on the same line, the output will have . For example,  print "Hello", "World!" will have a space between Hello and World!.
End of explanation
time.sleep(0.5);
print "Too bad"
import time
time.sleep(0.5);
print "Now its work"
print "We delete the time object to unload it from memory"
del time
time.sleep(0.5);
Explanation: The magic command (ipython specific)
Any command starts with % are magic command in ipython notebook. These % command can only be used in ipython instant. A full list of magic command can be found here: 
http://ipython.readthedocs.io/en/stable/interactive/magics.html. 
These commands are particularly useful in developing and debugging your program.
Import package and library
Python is rich in library. Use expression like
python
import xxxxxxx
or
python
from xxxxxxx import yyyyyy
to import library provided that you know the name of your library xxxxxx and objects yyyyyyy in the library xxxxxxx.
Package is not loaded at the beginning, you need to import it before using it.
