### Python cells
You can enter code in these cells, and running the cell runs the corresponding code.
%% Cell type:code id: tags:
``` python
print("Hello world!")
```
%% Output
Hello world!
%% Cell type:markdown id: tags:
#### Example
Execute the cell below to see the contents of variable `a`
%% Cell type:code id: tags:
``` python
importnumpyasnp
a=np.array([0,1,-5])
print(a)
```
%% Output

# Tasks
The goal of the following tasks is to make you familiar with the JupyterLab user interface.
## Task 1 - Getting to know JupyterLab and Notebooks
* Restart the kernel and run the whole notebook.
* Add a new Code Cell below with the following lines:
```python
b=1.5*a
b
```
* The notebook will always output the return value of the last line - collapse / hide the output.
* Markdown cells are a good way to document your thoughts - add a markdown cell above the last cell and describe the calculation.
* Open the *JupyterLab reference* and find the *The JupyterLab Interface* section.
## Task 2 - Working with cells
* Notebooks are **stateful** - this means that it saves the value of variables in a global scope until the kernel is restarted. Thus, the order of execution matters.
* Have a look at the *Notebooks* section in the *JupyterLab reference*.
* Drag & drop the cell containingcalculation of `b` to the top of the notebook and run the whole notebook without restarting the kernel.
* Now restart the kernel and run the whole notebook.
* What happened? Fix the error by moving the calculation of `b` to an appropriate place.
