I don't understand the width field in pprint in python

I don't understand this concept clearly. Could somebody give me some examples to demonstrate the concept for width in pprint in python?

Solution

  • Basically it tries to limit your output to a specific width.

    Here's an example:

    import pprint
stuff = ['spam', 'eggs', 'lumberjack', 'knights', 'ni']
pp = pprint.PrettyPrinter(width=80)
pp.pprint(stuff)

    result is:

    ['spam', 'eggs', 'lumberjack', 'knights', 'ni']

    but if you do the same thing but change the width(say to 10):

    import pprint
stuff = ['spam', 'eggs', 'lumberjack', 'knights', 'ni']
pp = pprint.PrettyPrinter(width=10)
pp.pprint(stuff)

    you get:

    ['spam',
 'eggs',
 'lumberjack',
 'knights',
 'ni']

    This is a modified example from the python docs ( http://docs.python.org/library/pprint.html ). For things like this, I find it easier to just open the python interrupter and play around and see how the commands react to what you enter.
