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.

Yes. Look at Cython. It does just that: Converts Python to C for speedups.

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

No. There is no such thing. Why would you want this, and how could it possibly work?

Converting Python Virtual Machine Code to C
In Section 3 I suggest some changes to the inner workings of Python which I argue will make it more amenable to optimization and high-speed implementations. My 211 program was inspired by the Toba program for Java, whose authors bill it as a ``way-ahead-of-time compiler'' [16]. The idea is that a Python application is profiled, and has the PVM code for its hot spots converted into C code by 211.

There are a few options, each with their own limitations:

Cython literally compiles Python code into C, so I’m not sure why that
doesn’t meet your requirements.

October 17, 2023 - Using Cython, you can speed up existing Python code by an order of 100x or more. This is possible because Cython converts some of the Python code to C by doing some basic code changes.
