Get file size, creation date and modification date in Python

I need to get file info (path, size, dates, etc) and save it in a txt but I don't know where or how to do it.

This is what I have:

ruta = "FolderPath"
os.listdir(path=ruta)
miArchivo = open("TxtPath","w")
def getListOfFiles(ruta):
 listOfFile = os.listdir(ruta)
 allFiles = list()
 for entry in listOfFile:
  fullPath = os.path.join(ruta, entry)
  if os.path.isdir(fullPath):
   allFiles = allFiles + getListOfFiles(fullPath)
  else:
   allFiles.append(fullPath)
 return allFiles

listOfFiles = getListOfFiles(ruta)
for elem in listOfFiles:
 print(elem)
 print("\n")
 miArchivo.write("%s\n" % (elem))
miArchivo.close()

The output is (only path, no other info): enter image description here

What I want is: V:\1111111\222222222\333333333\444444444\5555555555\66666666\Folder\File name -- size -- modification date and so on

Solution

  • https://docs.python.org/2.7/library/os.path.html#module-os.path 

    os.path.getsize(path) # size in bytes
os.path.ctime(path) # time of last metadata change; it's a bit OS specific.

    Here's a rewrite of your program. I did this:

    1. Reformatted with autopep8 for better readability. (That's something you can install to prettify your code your code. But IDEs such as PyCharm Community Edition can help you to do the same, in addition to helping you with code completion and a GUI debugger.)
    2. Made your getListofFiles() return a list of tuples. There are three elements in each one; the filename, the size, and the timestamp of the file, which appears to be what's known as an epoch time (time in seconds since 1970; you will have to go through python documentation on dates and times).
    3. The tuples is written to your text file in a .csv style format (but note there are modules to do the same in a much better way).

    Rewritten code:

    import os

def getListOfFiles(ruta):
    listOfFile = os.listdir(ruta)
    allFiles = list()
    for entry in listOfFile:
        fullPath = os.path.join(ruta, entry)
        if os.path.isdir(fullPath):
            allFiles = allFiles + getListOfFiles(fullPath)
        else:
            print('getting size of fullPath: ' + fullPath)
            size = os.path.getsize(fullPath)
            ctime = os.path.getctime(fullPath)
            item = (fullPath, size, ctime)
            allFiles.append(item)
    return allFiles

ruta = "FolderPath"
miArchivo = open("TxtPath", "w")
listOfFiles = getListOfFiles(ruta)
for elem in listOfFiles:
    miArchivo.write("%s,%s,%s\n" % (elem[0], elem[1], elem[2]))
miArchivo.close()

    Now it does this.
