How To Pass A Tuple To A Python Function

I've been trying to pass a tuple to a function that I created earlier, however, I m still not able to make it work. My objective is to pass a tuple containing a list of path+file f

Solution 1:

You're successfully passing the tuple to your own function. But os.path.getsize() doesn't accept tuples, it only accepts individual strings.

Also, this question is a bit confusing because your example isn't a path + file tuple, which would be something like ('C:\\', 'vd36e404.vdb').

To handle something like that, you could do this:

import os

def fileF(EXl):
    filesize= os.path.getsize(EXl[0] + EXl[1])
    print (filesize);

If you want to print values for multiple paths, do as Bing Hsu says, and use a for loop. Or use a list comprehension:

def fileF(EXl):
    filesizes = [os.path.getsize(x) for x in EXl]
    print filesizes

Or if you want to, say, return another tuple:

deffileF(EXl):
    returntuple(os.path.getsize(x) for x in EXl)

Solution 2:

import   osfor xxx in EXl:
    filesize= os.path.getsize(xxx)
    print (filesize);

Solution 3:

A way more elegant example:

map(fileF, EX1)

This will actually call fileF separately with each of the elements in EX1. And of course, this is equivalent to

for element in EX1:
    fileF(element)

Just looks prettier.
