If the C variant needs x hours less, then I'd invest that time in letting the algorithms run longer/again
"invest" isn't the right word here.
Build a working implementation in Python. You'll finish this long before you'd finish a C version.
Measure performance with the Python profiler. Fix any problems you find. Change data structures and algorithms as necessary to really do this properly. You'll finish this long before you finish the first version in C.
If it's still too slow, manually translate the well-designed and carefully constructed Python into C.
Because of the way hindsight works, doing the second version from existing Python (with existing unit tests, and with existing profiling data) will still be faster than trying to do the C code from scratch.
This quote is important.

It does just that: Converts Python to C for speedups. ... Of course that won't save you anything unless you add a bunch of cdef declarations and thereby introduce static typing (otherwise you just juggle opaque PyObject * stuff). And it will never get quite as fast as plain C because it's usually interfacing with Python (100% or more? only for plain numerical code ... More on stackoverflow.com
Are there any libraries that can easily convert Python to C/C#/or C++? Ones where a person doesn't have to "calibrate" it, just, pip install library and then they can have their Python code in C,C#,or C++?
The closest thing to what you're asking for would be Cython, which is a mostly-superset of Python and generates C code. Nuitka is similar, except that it also compiles said code into binaries. Although if you're expecting said C code to be easy to read, I'm afraid you'll be sorely disappointed. I'm not sure why you listed C# here, considering it's very different from either of the other two you mentioned. Why would you want a Python-to- transpiler anyway? If you want more performance, just write the performance critical parts in C or Rust in the first place, then have Python access them via CFFI. More on reddit.com

Is there any tool that can convert Python code into C++, Java, or C# code automatically? - Quora
What some people have done is to limit Python in certain ways so that it can be translated into relatively efficient C/C++ code, primarily by removing or restricting dynamic typing. However, the intent there is to still develop in Python and then just compile to something more efficient when executing/distributing the program. Check out Cython and RPython/PyPy for examples of this. ... Originally Answered: Are there any applications that convert Python code to C++ code automatically?

Converting Python Virtual Machine Code to C
The optimization of a Python program has a limit point, beyond which a programmer must resort to C code in order to get more speed. Not all programmers are willing or able to take this step. 211 is an experimental program which automatically converts Python virtual machine code into C.
