In findpython: Functions to Find an Acceptable Python Binary

Tests whether the python command is sufficient

Description

is_python_sufficient() checks whether a given python binary has all the desired features (minimum and/or maximum version number and/or access to certain modules).

Usage

is_python_sufficient(
  path,
  minimum_version = NULL,
  maximum_version = NULL,
  required_modules = NULL
)

Arguments

path	The path to a given python binary. If binary is on system path just the binary name will work.
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.

Value

TRUE or FALSE depending on whether the python binary met all requirements

Examples

try({
  cmd <- find_python_cmd()
  is_python_sufficient(cmd, minimum_version = "3.3", required_modules = "sys")
})
