How do i write 

   >>> x = int(raw_input("Please enter an integer: "))
    >>> if x < 0:
    ...      x = 0
    ...      print 'Negative changed to zero'
    ... elif x == 0:
    ...      print 'Zero'
    ... elif x == 1:
    ...      print 'Single'
    ... else:
    ...      print 'More'
    ...

this in IDLE. As soon as I hit enter after writting first line, it executes the first line and i am not able to write full code. I am very new to python, just started it today. Any help will be appreciated.

You don't have to execute it all in one go, if you do, then use a file for multiple runs or declare a function for a single run. Even if it executes earlier than you expected, you'll still have the entered value in the x variable. - KurzedMetal

Try File => New File in top menu. Then write your code in this windows and run it by F5 key (or Run in top menu)

1: Use semicolons between lines
2: Try iPython
3: Write it as a function, e.g.

def myfunc():
    x = int(raw_input("Please enter an integer: "))
    if x < 0:
        x = 0
        print 'Negative changed to zero'
    elif x == 0:print 'Zero'
    elif x == 1:print 'Single'
    else:print 'More'

Shift + Enter takes you to next line without executing the current line.

Can't write multi-line code in python console. Need a 3rd-party app.

Using the exec function along with multi-line strings (""") worked well for my particular use case:

exec("""for foo in bar:
  try:
    something()
  except:
    print('Failed')"""

If you do File --> New File, it should open a new savable window that you can write multiple lines and save as a .py file.
