Use uuid.uuid4() to create new file

Question

How do you concatenate the uuid.uuid4() value with a literal when creating a file? The below isn't correct but should illustrate what I'm attempting to do...

fo = open(uuid.uuid4() + ".txt", "wb")

Answer 1

You need to convert the uuid to a str :

>>> import uuid
>>> str(uuid.uuid4()) + ".txt"
'13eb9327-f40e-4ef1-8020-1c36af1b4b70.txt'

Answer 2

This version doesn't include the - in the string

fo = open(uuid.uuid4().hex + ".txt", "wb")

It's often a good idea to open the file using a context manager

with open(uuid.uuid4().hex + ".txt", "wb") as fo:
    # do stuff with fo
    # fo will be closed automatically

Here's an example in a loop

for item in data:
    with open(uuid.uuid4().hex + ".txt", "wb") as fo:
        fo.write(item)
