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
