_ Strptime in multiple Python threads

Since the _ strptime method in datetime and time in Python does not support multithreading, an error is reported during running:

 

Import datetime
Import thread
Import time

Def F ():
Datetime. datetime. strptime ("20100101", "% Y % m % d ")

For _ in xrange (3 ):
Thread. start_new_thread (F ,())
Time. Sleep (3)

Unhandled exception in thread started by <function f at 0x2b52c24e66e0>
Traceback (most recent call last ):

You can fix this bug in the source file, but for the user, lock it when using it ..

C = threading. rlock ()
Def F ():
With C:
Datetime. datetime. strptime ("20100101", "% Y % m % d ")
