Add Padding to a number in python

version = 1

version_padded = str(version).zfill(3) #add padding

Convert List to a dictionary simple way

myDic = dict.fromkeys(myList,"defaultValue")

Basic string Placeholder format

#method 1

"%s is so %s" % ("apple","sweet")

# Result: apple is so sweet

#method 2

user = "mohan"

id = "123"

print(f"hello {user}, your id is {id}")

Iterate over dictionary

dict = {"test2":"test1","test2":"test2"}

for key,value in dict.items():

print(key,value)

Rename Multiple files with similar names

import os

def moSeqRename(dir,oldStringToReplace,newString):

## defining variables

root = dir

oldList = os.listdir(root)

oldname = ""

newname = ""

oldfile = ""

newfile = ""

# loop through each file in the root

for oldname in oldList:

oldfile = root + oldname

newname = oldname.replace(oldStringToReplace,newString)

newfile = root + newname

os.rename(oldfile,newfile)

return

Copy to clipboard without any external modules

import os

os.system("echo -n '%s' | xclip -selection c" % string)

Remove first and last characters from string

mystring = mystring[1:-1]

Difference between lists

(list(set(li1) - set(li2)))

Edit each string in list

aovs = ["diffuse","specular","coat","transmission","sss","emission"]

aovs = ['/{0}/'.format(elem) for elem in aovs]

#this will return ["/diffuse/","/specular/" ...]

STRING MANIPULATION:

split

rsplit

lsplit

#Example:

path = "/usr/mohan-p/deskop/m.jpg"

split = path.split("/",3)[-1]

print split

##this will print desktop/m.jpg

PySide simple button ui

import sys

from PySide.QtCore import *

import PySide.QtGui as QtGui

####

window = QtGui.QWidget()

lay = QtGui.QVBoxLayout()

####font

font = QtGui.QFont()

font.setPointSize(25)

font.setBold(True)

####Create button

button = QtGui.QPushButton("Create Read")

button.setFont(font)

button.setMinimumSize(200,50)

button.setMaximumSize(400,100)

imagePath = "/usr/people/mohan-p/mohan_pugaz/RND/NUKE_PLUGINS/ICONS/M.png"

button.setStyleSheet("background-color: url("+imagePath+") ; color: black")

lay.addWidget(button)

window.setLayout(lay)

window.show()
