Now, this is much better because we can now just use this function over and over whenever we want to get the sum of two numbers as opposed to actually having to type the number plus another each time. įinally using the print function we have printed out the total, which is displayed in the terminal. We have then proceeded to call the function along with two arguments and the result is stored in a variable named total.

In the code above we have created a function named add_these() which takes in two arguments and returns the sum of the two arguments. In scenarios where the addition operator may be needed several times within the same program the best approach would be to create a function that can be reused multiple times.
In most cases, they may be used as part of functions or statements that form part of larger programs. In more realistic applications or programs, arithmetic operators are not used in isolation. In a similar manner, the addition operator returns the sum of two floating-point numbers written side by side.Īlternatively, we can also create a more elegant version of the above code snippets by creating variables that will hold the values whose sum we want to calculate as shown in the code below. The addition operator can also be used with floating-point numbers. Using the print function we can then display the result as shown in the snippet below. However, in order to display the results, we can simply create a variable that stores the sum of the two numbers. In its simplest form, the addition operator returns the sum of two numbers written side by side with the addition sign in between them. The addition operator is classified as an arithmetic operator among other operators such as the division operator and subtraction operator.

How to add numbers in Python by simple arithmetic operators In this article, we will explore how we can use the addition operator to add two numbers together. It is possible to use Python 3 in Jupyter Notebook for Python 2 by adding the kernel for Python 2.Python is capable of performing both complex and basic mathematical operations using the arithmetic operators or methods and constants available through the math library. The error message ImportError: No module named 'matplotlib' was caused by using Python 3 with Jupyter that was installed for Python 2.x. Try pasting the following simple Python code after In : and running it. Your output plot will appear in a small popup window that looks like the popup window in the below screenshot. Plt.savefig("") saves an image of your plot without all the extra window chrome in your Home directory.Ĭlick the black triangular-shaped Run button ( ▶ ) on the menu bar to run the code block.
Paste the whole code block together, not one line at a time. From the new notebook tab select File -> Rename, rename your new notebook to any descriptive name like sine_wave and click the OK button.Ĭopy the example Python code for plotting a sine wave listed below and paste it into the sine_wave notebook to the right of where it says In : using the keyboard combination Ctrl+ V. A new notebook tab will open in your default web browser. From the IPython Notebook interface click the New Notebook button. Instead use jupyter notebook to start Jupyter. The -pylab option was removed when they transitioned from IPython to Jupyter notebook. From the terminal run: ipython notebook -pylab
Open the ipython-notebook web browser interface. If Jupyter Notebook is installed, the command to start Jupyter is jupyter notebook and the first line of code to enable plotting in the current Notebook is %matplotlib inline.įollow these steps to generate the sine wave plot in the example from.

In Ubuntu 20.04 and later you can install Jupyter Notebook from the default Ubuntu repositories with the command sudo apt install jupyter-notebook jupyter. python-ipykernel is necessary for running Python 2.x programs in Jupyter Notebook, which otherwise supports only Python 3.x. In Ubuntu 18.04-19.10 you can install Jupyter Notebook from the default Ubuntu repositories with the command sudo apt install python3-notebook jupyter jupyter-core python-ipykernel. In Ubuntu 17.04 and 17.10 you can install Jupyter Notebook from the default Ubuntu repositories with the command sudo apt install jupyter-notebook jupyter-core python-ipykernel. In Ubuntu 14.04/16.04/16.10 follow the instructions in this answer to install Jupyter Notebook by upgrading IPython Notebook to Jupyter Notebook. You can optionally install Jupyter Notebook instead of IPython Notebook. The latest version of IPython Notebook is now known as the Jupyter Notebook. In Ubuntu 16.04 and earlier open the terminal type: sudo apt install ipython-notebook python-numpy python-matplotlib
