In this step-by-step tutorial, you'll learn how to use the Python zip() function to solve common programming problems. You'll learn how to traverse multiple iterables in parallel and create dictionaries with just a few lines of code.
uftrace is a function call graph tracer for C, C++, Rust and Python programs. It hooks into the entry and exit of each function, recording timestamps as well as the function's arguments and return values. uftrace is capable of tracing both user and kernel functions, as well as library ...
