Great! This error was easy to understand - “panda” doesn’t exist. Our bottom line says: ModuleNotFoundError: No module named 'panda' There is a lot of information in this message, let’s break it down starting at the bottom. Jupyter Notebook tries to be as helpful as possible. Let’s make that typo to see how Jupyter Notebook handles errors.Īs expected, we got an error. There is no package named ‘panda’, but it is an easy typo to make. Let’s move on to one more supportive feature in Jupyter Notebook: debugging.

Great job! As you code more, some functions will become second nature, but it can be helpful to know how to find the documentation until then. This can be confusing at first, so let’s look at an example. Jupyter Notebook will only write the result of the last line but will print anything contained in a print statement no matter where it occurs. Notice that we didn’t use a print() statement, but Jupyter Notebook wrote the result anyhow. We know the cell has finished running because a number appeared in the (this is a temporary cell number). Why?Īssigning variables doesn’t generate any output, so there is no result to write. When we run this cell, nothing appears in the output. This time, we will assign variables x = 2 and y = 3. Notice that the result is printed below the cell.
Start with a basic print statement: print("hello world"). When you write code in Jupyter Notebook, you will need to run each cell individually. For more on Jupyter’s useful features, check out the documentation. This section is a preview of how notebooks work. In this section, we will go through some examples of how to write code in Jupyter Notebook. You can also add a new cell by clicking the + button at the top. To run a cell, you can use the Run button or Shift + Enter.Ī new cell will appear after you run the cell you are working in. You can write small or large chunks of code in each cell and run each cell independently of others. You can open a new Python file by selecting New > Python3 When the notebook starts, you will be redirected to your default browser, and you will see a list of all the folders your program will have access to.
