- Does threading cause any more of a hassle in Python than Java?
<snip>
Hello,
From the python docs, it states that the threading design is loosely based upon the java module. Certainly, coming from Java I had little trouble getting used to python threading. However heres some gotchyas :
- The thing to beware of there is something in Python called the GIL. Read up about that before you start threading stuff - this will explain to you why there is no volatile keyword - this got me confused at first.
- There is no synchronize keyword, instead you have to use locks which can be obtained from the threading module
- There are no methods such as wait on an object (there is an event object you can get to call wait upon - again threading)
- The handy concurrent stuff which has been introduced in J2SE5.0 mainly isn't in python - through you do get Queues in Python (maybe more, I dunno?)
The GIL thing makes it easier to do threading with Python (there are disadvantages to the GIL but I won't get into that here - if you're interested read through the history on this group) but it's still threading so beware!
Cheers,
Neil
