Handling Errors for Input

Today I created options if the user typed in wrong data, they could change it. I also created options if the user typed in something that was not supposed to be typed, an error message would appear.

Program running

• Now the program runs forever until you type exit
• The program always clears the terminal when a new question comes and prints “NASA-Missions” at the top
• I made the program run forever by using while loop

Error Handling

• When users types in an option not in the options, the program shows an error message
• If the user types in data, the program asks the user for confirmation. If the user says no, the user can change the data.

Learned

• Learned about While loops
• learned about how continue and break work
• also learned the .lower() method

Took a very long time, and used a lot of if/elif/else statement. You can see in the picture just a glimpse of the hundreds of if/else.

Created option for Moon

Now you can choose between a planet and a moon. The program asks the user input for these things:

• moon name
• mission name
• gravity
• extra info

Then this is stored into a dictionary. Then this puts the data into an excel spreadsheet.

Improvements

I still need to ask the user for the distance of the planet/moon from earth. Then I can calculate the fuel needed to get there.

Maybe use SQL for data?

The user of dictionaries helped a lot in this program. Now I fully understand how it works.

Finished the README file

Created a new project and allowed user to create a new mission and set some key values for the mission.
