New submission from Red Glyph <redgl...@gmail.com>:
Tested with - Python 3.7.4, 64-bit, Windows version (installer version) - python-3.8.0b3-embed-amd64.zip - python-3.7.2.post1-embed-amd64.zip on Windows 7 x64 Professional time.process_time() always returns the same value. If I check the value of time.process_time_ns(), sometimes it is constant, sometimes I observe a few changes, then it becomes constant too. Here is a log of an example session, I'm waiting at least 1-2 seconds between each command: Python 3.7.4 (tags/v3.7.4:e09359112e, Jul 8 2019, 20:34:20) [MSC v.1916 64 bit (AMD64)] on win32 Type "help", "copyright", "credits" or "license()" for more information. >>> import time >>> time.process_time() 0.1092007 >>> time.process_time() 0.1092007 >>> time.process_time_ns() 109200700 >>> time.process_time_ns() 124800800 >>> time.process_time_ns() 124800800 >>> time.process_time() 0.1248008 >>> time.process_time() 0.1248008 >>> time.process_time() 0.1248008 >>> time.process_time_ns() 124800800 >>> time.process_time_ns() 124800800 >>> time.process_time_ns() 124800800 >>> time.process_time_ns() 124800800 >>> time.clock() Warning (from warnings module): File "__main__", line 1 DeprecationWarning: time.clock has been deprecated in Python 3.3 and will be removed from Python 3.8: use time.perf_counter or time.process_time instead 77.006126126 >>> time.clock() 79.245575778 >>> time.clock() 80.801103036 >>> time.process_time() 0.1248008 >>> ---------- components: Library (Lib), Windows messages: 349745 nosy: Red Glyph, paul.moore, steve.dower, tim.golden, zach.ware priority: normal severity: normal status: open title: time.process_time() constant / erratic on Windows type: behavior versions: Python 3.7, Python 3.8 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue37859> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
