+Micropython is based on a certain version of Python (currently 3.4), so certain Python features may not be present at all, depending on the version used as reference. 
+Other features may simply yield different results as compared to CPython, depending on the version CPyton is based on. And then there are certain features that are simply 
+implemented differently in order to gain speed or smaller memory footprint. Please refer to :
+
+ https://docs.micropython.org/en/latest/genrst/index.html
+
+
+
+A description of limitations and differences of builtin features wrt CPython can be found here :

+### the following test directories and files are currently available
+
+# generic tests for all tools
+basics
+cmdline : Only works with command line Python, e.g. Unix
+cpydiff : tests with known discrepancies to CPython, therefore to be omitted
+extmod
+feature_check
+float
+frozen
+import : many tests require files on the board filesystem, but these are not copied by default. All those tests have been manually tested and verified to work as expected
+inlineasm
+internal_bench : run by run-internalbench.py; some need “ticks” function or will fail; also require module bench.py which must be on the local flash
+io : need files in local flash (io/data/*), but those are not copied by default
+jni : tests to be run in environment with JAVA available, ie Unix, Windows, ...
+micropython
+misc
+multi_bluetooth
+multi_net
+net_hosted
+net_inet
+perf_bench : used with run-perfbench.py for benchmarking
+stress
+thread
+unicode
+unix : exclude mod_os.py, but use time.py for psoc6; in general to be run only on Unix platform !
