Pure python custom print implementation

Rprint is a faster pure python print implementation.

• fast io storage support
• just for fun
• like print, but better!

from rprintlib import Rprint
rprint = Rprint()

Main features:

• by default Rprint prints nothing to console(stdin)
• You can access printed data as list anytime with rprint.ret() or str(rprint) and repr(rprint)

from rprintlib import rprint #predefined rprint object
>>> rprint(12, 33, None, 'String', sep=' - ')
>>>
>>> rprint(1.23)
>>> 
>>> rprint.ret() # ->list copy
>>> ['12 - 33 - None - String\n', '1.23\n']
>>> str(rprint) # ->str
>>> '12 - 33 - None - String\n1.23\n'
>>> repr(rprint) # ->repr 
>>> "<rprintlib.rpmain.Rprint('12 - 33 - None - String\\n', '1.23\\n', sep='', end='')>"
>>> iter(rprint)
>>> <list_iterator object at 0x0000013AD992D320>

Why rprint?

• It’s easy to use
• 8 times faster than print with stdout output and 10.7 without it
• It’s open-source and pure-pythonized
• Why not?

Installation

FAQ

Can i print to console or file with rprint?

yes:

import sys
rprint('something', file=sys.stdout)
>>> 'something'

It is possible to use starred expressions?

import sys
rprint(*('sure', 'why', 'not'), sep=" - ", file=sys.stdout)
>>> 'sure - why - not'

I need to type file= everytime i want to use stdout or other writable file?

Well, no. You can do something like:

import sys
rprint.rtdout.stdout = sys.stdout
rprint(1)
>>> 1
rprint('rtdout - default class for storing output source')
>>> 'rtdout - default class for storing output'

Or even better solution:

from rprintlib import sprint # predefined stdout Rprint object
sprint(2)
>>> 2

So, there are two base classes?

Yep. Here’s the argument list for each of them:

Rprint(self, *objects, sep=’ ‘, end=’\n’, flush=False, file=None)

Rtdout(self)

and usable methods and attributes for Rprint:

• .flush(self) flushes cached output if possible (can raise AttributeError)
• .ret(self) returns list of cached calls (only if rprint.rtdout.stdout is None or False)
• .write(self, *objs) don’t use that one directly. It was created for using Rprint object as alternative file storage:

  print("something", file=rprint)
  print(rprint.ret())
  >>> ["something\n"]
  

  or

  import sys 
  # redefine stdout to rprint storage 
  sys.stdout = rprint 
  print(1)
  print(2)
  print(3)
  sys.stdout = sys.__stdout__ #redefine stdout to default console out
  print(rprint.ret())
  >>> ['1\n', '2\n', '3\n']
  

• .rtdout.stdout Rtdout instance for current rprint object, that stores default out file value. Default to None
• .rtdout.getstdout() Get current stdout for rprint object

You can also use rprint with context manager:

with rprint:
    rprint(12)
    print(rprint.ret())
    >>> ['12\n']
# flush() on exit. Storage is empty now
print(rprint.ret())
>>> []
