Question 1

• Read the 'education.csv' file into a DataFrame object.

• Calculate and print a new table, where each row represents a type of education facility, with the following columns:

  • 'type'—Facility type

  • 'count'—Total number of facilities of that type

  • 'valid_address'—The percent of facilities with a valid address (i.e., other than np.nan). The values should be strings of the form '86.1%' (with one decimal).

	type	count	valid_address
0	בית ספר	65	84.6%
1	גן ילדים	395	83.3%
2	חווה חקלאי	1	0.0%
3	מרכז מדעים	2	50.0%
4	על יסודי	26	69.2%

Question 2

• The text file named 'bgu.wkt' (see Sample data) contains a WKT string representing the geometry of the BGU logo.

• Read the WKT string from the 'bgu.wkt' file, using the open and .readline methods (see Working with files). Convert the string into a shapely geometry

• Note: Do not copy and paste the WKT string into your code! You need to read it from the 'bgu.wkt' file.

• Display the logo graphically.

• Calculate the area of the logo.

0.21286694897980007

• Calculate a circle that is enclosing the logo. To do that, first calculate the average of x-axis bounds and the average of the y-axis bounds, then construct a point according to those x and y values, and finally buffer the point to a distance of your choice so that the logo is completely within the buffer.

• Calculate the geometry of the difference between the logo and the bouding circle you calculated, then plot it.
