> Having recently moved from Python (where the documentation is amazing) Huh? Python's online documentation is horrible. In addition to what vbezhenar said, there are gems like this: The arguments shown above are merely the most common ones, described below in Frequently Used Arguments (hence the use of keyword-only notation in the abbreviated signature). The full function signature is largely the same as that of the Popen constructor - most of the arguments to this function are passed through to that interface. (timeout, input, check, and capture_output are not.) [1] "Largely the same"? What, am I supposed to divine the actually available parameters? For built-in types, the docs are missing a way to quickly list all available methods and properties. You have to somehow piece it together from various ABCs.
