woob.tools.misc.find_exe(basename)

Find the path to an executable by its base name (such as ‘gpg’).

The executable can be overriden using an environment variable in the form NAME_EXECUTABLE where NAME is the specified base name in upper case.

If the environment variable is not provided, the PATH will be searched both without and with a “.exe” suffix for Windows compatibility.

If the executable can not be found, None is returned.

Try to get backtrace as string. Returns “Error while trying to get backtrace” on failure.

>>> get_bytes_size(2, 'KB')

woob.tools.misc.input(prompt=None, /)

Read a string from standard input. The trailing newline is stripped.
