Tips for writing multi-platform Python code
Creating Remediation Scripts | Forcepoint DLP | v8.4.x, v8.5.x, v8.6.x
Additional note: When writing multi-platform code in Python, it is best to avoid making assumptions about the environment, if possible. Python helps quite a bit in that regard by providing facilities that performs certain actions regardless of the platform. A very common example is concatenating filenames and folders.
The following code is not cross-platform because it will fail on a Linux machine.
if not folderName[-1:]=='\\':
folderName+=r'\\'
pathName=folderName+fileName
Python provides a comprehensive library of path handling routines (os.path) that works regardless of the operating system the script runs on:
pathName = os.path.join(folderName,fileName)
The same applies to other operations such as splitting a path. For example, consider the following script:
pathParts = pathName.rsplit('/',1)
if len(pathParts)==2:
folderName,fileName=pathParts
It would work just as well using the following:
folderName,fileName = os.path.split(pathName)
These scripts would work on both operating systems, and also cover corner cases you may not have considered (for example, the input is just a folder and not a filename).
