Performance differences between Python and C

Question

Working on different projects I have the choice of selecting different programming languages, as long as the task is done.

I was wondering what the real difference is

Answer 1

You will find C is much slower. Your developers will have to keep track of memory allocation, and use libraries (such as glib) to handle simple things such as dictionaries, or lists, which python has built-in.

Moreover, when an error occurs, your C program will typically just crash, which means you'll need to get the error to happen in a debugger. Python would give you a stack trace (typically).

Your code will be bigger, which means it will contain more bugs. So not only will it take longer to write, it will take longer to debug, and will ship with more bugs. This means that customers will notice the bugs more often.

So your developers will spend longer fixing old bugs and thus new features will get done more slowly.

In the mean-time, your competitors will be using a sensible programming language and their products will be increasing in features and usability, rapidly yours will look bad. Your customers will leave and you'll go out of business.
