A Print function for different versions of python

Gribouillis 1 Tallied Votes 782 Views Share

This snippet defines a Print function which can be used with python 2.4, 2.5, 2.6 and 3.0 (for 3.0 this is just the built-in print function). It's interface is that of the python 3.0's print. It simplifies the task of writing transitional code which runs under python 2.5 and python 3.0.

where would you put this to have it as a built in function?
i have python 2.5 but it says python2.4.6 if that helps

@leegeorg07, you could make it built-in for the rest of the execution of your script by making it a part of the __builtins__ module by adding these lines at the end:

    import __builtin__   # use "builtins" in Python 3
    __builtin__.Print = Print

Although this practice is often frowned-up.

@martineau you are knew to our forums, but we have a rule going on here: if the thread is older than 3 months, there's no need to resurface it. I'm not saying that your advice is bad. I'm just saying that @leegeorg07 posted his question 4 years ago, and I doubt he's still searching for an answer to it.

@Lucaci-Andrew, Yes I'm new to the forums and knew that @leegeorg07's message was old, but thought a reply was worthwhile mainly for any other folks who might stumble across the original code snippet and related thread as I myself did.

As for my mistake, early in the morning.
As for your reply: this can be easily solved searching it through {insert your preferred search engine}.
