### Can Python run C code?

Compile Python to C Python code can make calls directly into C modules. Those C modules can be either generic C libraries or libraries built specifically to work with Python.

Is Python fast enough?

In terms of raw performance, Python is definitely slower than Java, C# and C/C++. However, there are other things that matter for the user/observer such as total memory usage, initial startup time, etc. For most things, Python is fast enough 😉 This site lets you compare different programming languages to each other.

Why is C so fast?

You can easily write a C program that runs slower than programs written in other languages that do the same job. The reason why C is faster is because it is designed in this way. It lets you do a lot of “lower level” stuff that helps the compiler to optimize the code.
