python and IDE-Editors – Few things to remember

for daily work i use some more or less suitable IDE’s for python development, like PyCharm, or Eclipce with pydev.

but i cannot go without my sublime editor

sublime already packaged with default python interpreter, which is what makes it super powerful out of the box python programming tool for quick scripts that do not require any custom modules or what not.

but when there is a need to switch to system-default or alternative version of python,

you can create a simple configuration.

more about this is described here

few python quickies

this is a snippet from an data-audit application i made for work.

i often have to convert between file sizes and these are just quick and handy functions to keep around.

def _printDict(d):
    for key, value in d.items():
        print '%s = %s' % (key, value)

def _formatSize(s):
    if s > 1024 * 1024:
        return '%10s (~%s Mb)' % (s, s / (1024 * 1024))
    if s > 1024:
        return '%10s (~%s Kb)' % (s, s / 1024)
    else:
        return '%10s' % s

def _formatSizeInMb(s):
    sizemb = float(s) / (1024 * 1024)
    return '%0.2f' % sizemb

Open and add text to image in Python

Here i found an oldrer code snipped that served as my RnD for a thumbnail application that i made for my studio. This code snipped uses very simple.  here is what this snippet does:

We create a new Canvas 512×512, and open another image from our HDD, Resizing the image to desired size, in my case it was 128×128, and i am sure i had a good reason for all these sizes :), we also set the Font that we want to use, here i explicitly copied font file to so opened location, just to avoid some security troubles with Windows folder and all that, we combine our canvas and image together and add text at some location, in red, and as a last step – save this new image somewhere on the disk.

Now, why is this here, often , in production i come about really frequently repeated actions, of assembling some sort of Daily report or something similar, so, if this code is adapted into a very simple structure, you can have a pretty powerful application that allows to save a lot of time in assembly of these assets… really up to your imagination how one could use it.

i want to have this code here for my own reference, and for anyone who is after some ideas for automation.. or what not 🙂
 

from PIL import Image, ImageFont, ImageDraw
font = ImageFont.truetype("C:/arial.ttf", 22)
im = Image.new("RGB", (512, 512), "black")
im2 = Image.open("c:/1.png")
im2 = im2.resize((128,128))
draw = ImageDraw.Draw(im)
im.paste(im2, (10,10))
draw.text((100,100), "Hello", font=font, fill=(255,0,0))
im.save("C:/test.jpg")

Maya Open/Close CommandPort

This is a pretty popular code snippet that i am rather reposting for my own sake, as i always have to google for it online, and i find some of the code being modified here and there, so i am posting my own version on my own blog. that i have modified for my own purposes 🙂 and if anyone happens to see this: enjoy 🙂
 

import maya.cmds as cmds
# Close ports if they were already open
try: cmds.commandPort(name=":7001", close=True)
except: cmds.warning('Could not close port 7001')
try: cmds.commandPort(name=":7002", close=True)
except: cmds.warning('Could not close port 7002')
# Open ports
try: cmds.commandPort(name=":7002", sourceType="python")
except: cmds.warning('Could not Open port 7002')	
try: cmds.commandPort(name=":7001", sourceType="mel")
except: cmds.warning('Could not close port 7001')
