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.

The uuid module provides immutable UUID objects (the UUID class) and the functions uuid1() , uuid3() , uuid4() , uuid5() for generating version 1, 3, 4, and 5 UUIDs as specified in RFC 4122. If all you want is a unique ID, you should probably call uuid1() or uuid4() .
The thread-unsafe part of Python 2.5's uuid. uuid1() is when it compares the current current timestamp to the previous timestamp. Without a lock, two processes can end up comparing against the same globally saved timestamp.
As Giacomo Alzetta says, UUIDs can be compared as any other object, using == . The UUID constructor normalises the strings, so that it does not matter if the UUID is in a non-standard form. You can convert UUIDs to strings using str(x) , or strings into UUID objects using uuid.
uuid1() is defined in UUID library and helps to generate the random id using MAC address and time component. bytes : Returns id in form of 16 byte string. int : Returns id in form of 128-bit integer. hex : Returns random id as 32 character hexadecimal string.
you can try this !
a = uuid.uuid1() str(a) --> '448096f0-12b4-11e6-88f1-180373e5e84a' If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
