‫So we have started this reporter's notebook from an academic and then we go to now to create a new notebook.
‫Click on this new button in the top right corner and click on Python three.
‫This will open a new notebook in the new tab.
‫This is the forage, a notebook interface and notebook you write and run your codes and small segments,
‫and this segments are called cells.
‫Apart from executing your code, the cells can also be used for commenting, and it is really helpful
‫to make your code readable and easy to follow to write the code.
‫You just have to click on this cell and, for example, to actual numbers, you can just write 2+2.
‫So this is where you will write your codes to execute this code.
‫Just press control.
‫Enter.
‫So you can write your codes in the cell and you will get the output just below.
‫You can see what input we have and and for all the outputs we have out
‫on the top, you can see different menu items.
‫File contains general options like saving, printing or renaming added contents related options like
‫cut cell copy, cell based cell or delete cell.
‫View contains interface related options and inserts contents option to insert new cells.
‫Since menu item contains execution related options, and as the name suggests, help contains references
‫and manuals on how to use your partner notebook.
‫You can also find a list of shortcuts from your.
‫Now, most of the options we are going to use are also available in the form of buttons.
‫So suppose if I want to rename this file as lecture one, I will do that by clicking on this file name
‫and title and just rename it to lecture one.
‫To save this file, we can click on the Save button.
‫It will automatically save your file and your default directory.
‫And next time you open Jupyter Notebook, you will be able to see this file in the ordinary directly
‫from Jupyter Notebook homepage.
‫There are also buttons to cut copy paste.
‫We also have a button to execute our codes.
‫So again, if I if I click on my cell and click on run, it will execute the same.
‫Now you can see this drop down menu is code.
‫This means the cell we have selected, it's containing a code.
‫If I wanted to contain a comment, I can change it to either raw or markdown formatting.
‫If I change it to download Raw, our Python kernel will note that the sale the content of this particular
‫cell is just for commenting and it will not execute it.
‫The presence of this feature make over code more readable and understandable, so I will go ahead and
‫change the format of this said it to me, which is modern.
‫You can see when I'm changing my cell to mark down, the input symbol goes away.
‫There is no input symbol here and what symbols are present on the in the front of codes.
‫I can write anything in this empty cell, and Python reads this as a command.
‫So let's go ahead and write.
‫This is an empty cell.
‫Meltdown cells also supports modern formatting, so if I want to give her name, I can use bone symbol.
‫So will give up hiding, hiding one.
‫If I execute this.
‫You can see, since I use bomb symbol in front of the siding one.
‫The fine for hiding one is in the hiding format.
‫We can also use multiple bones symbols to change this size.
‫So if I use those symbols for heading to.
‫You can see heading to is slightly smaller than heading one.
‫You can also use three, four, five or six bond symbol to change the size of the settings.
‫You can also use as strict symbols to give bullets.
‫So if I write a strike, if I write bullet point, this strict symbol will be directly converted into
‫a bullet.
‫So.
‫If I execute it, you can see the stick symbols are now converted into bullets.
‫And we are seeing all our points and proper bullet points.
‫There are multiple features for editing Mondo.
‫You can Google it, and if you want, you can learn more about this formatting.
‫Again, note that Mondo not just for commenting your python is not actually executing this sentence.
‫The next cell format is raw.
‫Raw is similar to markdown, but it does not support formatting.
‫So if you convert it to raw.
‫If you converted to drop, it will remain like this.
‫You will not be able to get formatting out of this cells again.
‫Roy's also for commenting and Python will not execute it.
‫Code is the format in which we write our codes, and Python will only execute cells that are marked
‫death squads.
‫You can see the format for this cell is scored.
‫Therefore, I can use my codes in this cell.
‫So if I write 2+2, I can execute it either by clicking this run button or by pressing the shortcut
‫key that is control, enter or not.
‫I will click on this red button.
‫Similarly, if I write five plus three, this time, I will lose control under control, and there is
‫no shortcut to run the Senate to execute the Senate.
‫But most of the time, we also want to enter a blank cell, been in this cell.
‫In that case, I can use oil and instead of controlling the alternator, will execute the cell.
‫Also, it will insert a blank cell.
‫Just below this cell, so for all alternator, it has executed the sale and it has inserted a new sale,
‫a new blank sell just below this.
