I'm pretty new to Python and am completely confused by .join() which I have read is the preferred method for concatenating strings.
I tried:
strid = repr(595) print array.array('c', random.sample(string.ascii_letters, 20 - len(strid))) .tostring().join(strid) and got something like:
5wlfgALGbXOahekxSs9wlfgALGbXOahekxSs5 Why does it work like this? Shouldn't the 595 just be automatically appended?

Join is a synchronization method that blocks the calling thread (that is, the thread that calls the method) until the thread whose Join method is called has completed. Use this method to ensure that a thread has been terminated. The caller will block indefinitely if the thread does not terminate.
lang. Thread class provides the join() method which allows one thread to wait until another thread completes its execution.
The join() method takes all items in an iterable and joins them into one string. A string must be specified as the separator.
Simply put, How does the join() method of Thread works internally, I know that using join() method you can join one thread at the end of other. For example, if we use thread. join() in main thread, then the main thread should wait until run method of Thread thread finishes completely.
Look carefully at your output:
5wlfgALGbXOahekxSs9wlfgALGbXOahekxSs5 ^ ^ ^ I've highlighted the "5", "9", "5" of your original string. The Python join() method is a string method, and takes a list of things to join with the string. A simpler example might help explain:
>>> ",".join(["a", "b", "c"]) 'a,b,c' The "," is inserted between each element of the given list. In your case, your "list" is the string representation "595", which is treated as the list ["5", "9", "5"].
It appears that you're looking for + instead:
print array.array('c', random.sample(string.ascii_letters, 20 - len(strid))) .tostring() + strid If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
