If the python interperter only calls functions when they are called, and if some functions contain other functions, wouldn't it slow the performance of executing a program? How do different programming languages deal with this issue of having to conjure things as it runs the code? Reference ?

Yes, calling functions within functions can slow down the performance of executing a program, as each time a function is called, it requires time to be processed and executed. Different programming languages deal with this issue in different ways.
Some programming languages, such as C and C++, compile the code into machine code before executing it. This allows for the compiler to optimize the code and reduce the number of function calls, improving performance.
Other programming languages, such as Python, are interpreted. This means that they are executed line by line, and do not have the ability to optimize code before execution. To address this issue, some interpreted languages, like Python, use Just-In-Time (JIT) compilers, which compile the code on the fly during execution and can optimize the code as it runs.
Additionally, other languages, such as Java, use a combination of compilation and interpretation. Java code is compiled into bytecode, which is then executed by the Java Virtual Machine (JVM). The JVM can optimize the code as it runs, similar to JIT compilers.
Overall, different programming languages have different methods for dealing with the issue of slow performance due to function calls within functions, but all have ways to optimize code execution and improve performance.
