I think that Hendrik answered it well enough in that in 'embedded' space the 'C' language is it going to reach into
the details of systems programming.
 
To learn embedded systems and to read other programmers code to understand it purpose of various functions, like for
example how to 'talk' to a LCD display, and how it really is working may require at least be able to *read* the 'C' language.
 
For more general programming of applications not having to manage memory and leave at least that detail
to a "gc" (garbage collector) of which python does have. (hint: a gc is never cheap in it usage of resources)

To learn embedded systems you're learning almost three separate pipelines of *new* knowledge :

1. The tool-chain of the host machine: cross-compiler (if used), upload/download utilities, optional debugging utilities.
2. The target machine e.g. the hardware processor and aux subsystems (SPI, I2C, async serial, GPIO, ADC, DAC, Timers, memory)
3. the target "systems" language and (very many) optional libraries

(the original question was category 1)

You completely misunderstood the analogy I'm making...

Scenario:  OP is fighting with Python a bit in order to use MicroPython
(or a variant thereto) to program a microcontroller.

I'm telling him that *IF* he's trying to do this as more than a
"one-off", he might as well learn C/C++ (via Arduino) now, rather than
waiting on it.

Python = "Cheap tool" (It'll get the job done, if all you need is this
one thing)

C/C++ = "Expensive tool" (It'll "hurt the wallet", but you'll have it
forever).
