How do I convert a Python UUID into a string?
PythonStringUuidPython Problem Overview
I need to be able to assign a UUID to a user and document this in a .txt file. This is all I have:
import uuid
a = input("What's your name?")
print(uuid.uuid1())
f.open(#file.txt)
I tried:
f.write(uuid.uuid1())
but nothing comes up, may be a logical error but I don't know.
Python Solutions
Solution 1 - Python
you can try this !
a = uuid.uuid1()
str(a)
--> '448096f0-12b4-11e6-88f1-180373e5e84a'
Solution 2 - Python
You can also do this. Removes the dashes as a bonus. link to docs.
import uuid
my_id = uuid.uuid4().hex

UPDATE: trimmed UUIDs (without the dashes) are functionally identical to full UUIDS (discussion). The dashes in full UUIDs are always in the same position (article).
Solution 3 - Python
I came up with a different solution that worked for me as expected with Python 3.7.
import uuid
uid_str = uuid.uuid4().urn
your_id = uid_str[9:]
Solution 4 - Python
[update] i added str function to write it as string and close the file to make sure it does it immediately,before i had to terminate the program so the content would be write
import uuid
def main():
a=input("What's your name?")
print(uuid.uuid1())
main()
f=open("file.txt","w")
f.write(str(uuid.uuid1()))
f.close()
I guess this works for me
Solution 5 - Python
It's probably because you're not actually closing your file. This can cause problems. You want to use the context manager/with block when dealing with files, unless you really have a reason not to.
with open('file.txt', 'w') as f:
# Do either this
f.write(str(uuid.uuid1()))
# **OR** this.
# You can leave out the `end=''` if you want.
# That was just included so that the two of these
# commands do the same thing.
print(uuid.uuid1(), end='', file=f)
This will automatically close your file when you're done, which will ensure that it's written to disk.
