Determines whether or not it can find a suitable python cmd

Description

can_find_python_cmd() runs find_python_cmd() and returns whether it could find a suitable python cmd. If it was successful its output also saves the found command as an attribute.

Usage

can_find_python_cmd(
  minimum_version = NULL,
  maximum_version = NULL,
  required_modules = NULL,
  error_message = NULL,
  silent = FALSE
)

Arguments

minimum_version	The minimum version of python it should be. Should be a string with major and minor number separated by a .. If left NULL won't impose such a restriction.
maximum_version	The maximum version of python it should be. Should be a string with major and minor number separated by a .. If left NULL won't impose such a restriction.
required_modules	Which modules should be required. Can use a single | to represent a single either-or requirement like "json|simplejson". If left NULL won't impose such a restriction.
error_message	What error message the user will see if couldn't find a sufficient python binary. If left NULL will print out a default message.
silent	Passed to try, whether any error messages from find_python_cmd() should be suppressed

Value

TRUE or FALSE depending on whether find_python_cmd() could find an appropriate python binary. If TRUE the path to an appropriate python binary is also set as an attribute.
