You can manually download IPython from GitHub or PyPI. To install one of these versions, unpack it and run the following from the top-level source directory using the Terminal:,If you already have Python installed and are familiar with installing packages, you can get IPython with pip:,If you are looking for installation documentation for the notebook and/or qtconsole, those are now part of Jupyter.,Download and install Continuum’s Anaconda or the free edition of Enthought’s Canopy.
pip install ipython
conda update conda conda update ipython
enpkg ipython
pip install.

Python is a programming language in which we write computer programs. These programs are stored in text files that have the ending .py, for example hello.py which may contain:
print("Hello World")
Python is also a computer program (the technical term is ''interpreter'') which executes Python programs, such as hello.py. On windows, the Python interpeter is called python.exe and from a command window we could execute the hello.py program by typing:
python.exe hello.py
On Linux and OS X operating systems, the Python interpreter program is called Python, so we can run the program hello.py as:
python hello.py
You should see output similar to this in the lower right window of spyder (you may also see a plot appearing):

If you install Python in other ways than through the Anaconda distribution and, for example, you have only installed the numpy, scipy and matplotlib package, the program's output would be:
Testing numpy...- > numpy OK
Testing scipy...- > scipy OK
Testing matplotlib...- > pylab OK
Testing sympy...Could not
import 'sympy' - > fail
Testing pytest...Could not
import 'pytest' - > fail
Update the conda program (this manages the updating) by typing the following command into the console:
conda update conda
# DON 'T DO THIS!!conda install--yes numpy
