Julia is a high-level, high-performance, dynamic programming language for numerical computing. Users can import arbitrary Python modules and libraries into Julia. PyCall package is provided for calling Python from Julia code. You can use PyCall from any Julia code, including within Julia modules. And add this package to the Julia environment with Pkg.add (“PyCall”).
PyCall provides many routines for manipulating Python objects in Julia via a type PyObject. In most cases, PyCall automatically makes the appropriate type conversions to Julia types based on runtime inspection of the Python objects.
To Import Python Packages in Julia. Follow the steps below:
Step 1: using Pkg
Step 2: Pkg.add(“PyCall”)
Step 3: using PyCall
Step 4: @pyimport python_library_name
or
Step 4: pyimport(“python_library_name”)
Example 1:
Julia
# Julia program to import math python package using Pkg # add PyCall package Pkg.add("PyCall") # use PyCall using PyCall # import python library @pyimport math print(math.sin(90)) |
Example 1
Example 2:
Julia
# Julia program to import numpy python library using Pkg # add PyCall package Pkg.add("PyCall") # use PyCall package using PyCall # import python library @pyimport numpy # or np = pyimport("numpy") # define array using numpy array1 = numpy.array([1, 2, 3, 4, 5, 6, 7, 8, 9]) # print array print(array1) print('\n') # print array mean print(numpy.mean(array1)) |
