python dictionary is thread safe? -

-

Some said that the dragon dictionary thread is safe, does it mean that I can not modify or edit items in a dictionary Can not I?

Two concepts are completely different, that means two threads modify the same object at the same time The system can be left in an inconsistent state.

He said, you can not modify a dictionary while walking on it. See.

The dictionary P should not be mutated during recurrence. It is safe to modify the values ​​of the keywords (as is the Python 2.1), as you repeat on the dictionary, but The keys are not set up for such a long time only.

I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code.

This will allow dragon to search your modules (otherwise, Python looks for the .py module).
