A runtime system creates a layer over the operating system (OS) that contains other programs that handle the tasks needed to get the main program running.
These other programs handle tasks such as allocating memory for the main program and scheduling it..
Examples of compiled languages include Java, C, and C++..
For the most part, Python is an interpreted language and not a compiled one, although compilation is a step.
Python code, written in . py file is first compiled to what is called bytecode (discussed in detail further) which is stored with a . pyc or ..
Compile-time is the time at which the source code is converted into an executable code while the run time is the time at which the executable code is started running..
Compile time is the period when the programming code (such as C#, Java, C, Python) is converted to the machine code (i.e. binary code).
Runtime is the period of time when a program is running and generally occurs after compile time.Aug 16, 2023.
Runtime is the final phase of the program lifecycle in which the machine executes the program's code.
The other phases include: Edit time.
When the source code of the program is being edited.
This phase includes bug fixing, refactoring, and adding new features..

Programmers are not machines that write the perfect and correct solution on their first try.
We have a workflow of writing a program, compiling it and testing, and then re-writing because the first (and second and..) attempt was wrong.
If we have to wait for the compilation part, that slows down the entire workflow..
Simply put "The compilation time doesn't really matter" All that matters is how fast the program executes on a discreet set of provided input. compile time may vary programmer to programmer according to their program size for same task but run time only vary according to algorithm, thus run time matters..
Basically if your compiler can work out what you mean or what a value is "at compile time" it can hardcode this into the runtime code.
Obviously if your runtime code has to do a calculation every time it will run slower, so if you can determine something at compile time it is much better.
Eg.
In computer science, compile time refers to either the operations performed by a compiler (the "compile-time operations"), programming language requirements that must be met by source code for it to be successfully compiled (the "compile-time requirements"), or properties of the program that can be reasoned about at compile time.
"Compile time" is when you build your code - when the compiler converts your source code into IL. "Runtime" is when your code is executed - for ASP.NET, when a page request is made. (Personally I prefer the term "execution time" to distinguish between that and "the Common Language Runtime (CLR)" - aka the virtual machine.) .
The compiler produces compile time errors and usually indicates what line of the source code is causing the problem.
If a program's source code has already been compiled into an executable program, it may still have bugs that occur while the program is running.
