Answer 4

feature layer

Question 5

Which function would you use to create a feature class from a selection? Copy Rows? Copy Features?

Answer 5

Answer 6

copy rows

Question 7

You need to make a selection on a feature class for all the features that have a value of ‘38G9’ in its SOIL_TYPE field. Do you use a SelectLayerByAttribute or a SelectLayerByLocation to perform the selection?

Answer 7

select by attribute

Question 8

You need to make a selection on a line feature class where its lines intersect the polygons of a second layer. Do you use a SelectLayerByAttribute or a SelectLayerByLocation to perform the selection?

Answer 8

select by location

Question 9

Name 2 differences between a feature class and a feature layer

Answer 9

a feature class is a group of actual files/tables, a feature layer is the representation of a feature class in memory. A feature class remains in the computer even after a pro session ends, a feature layer ceases to exist when ArcGIS pro is closed. A feature class does not save selection information and a feature layer does.

Question 10

Name 2 differences between a table and a table view.

Answer 10

Tables can be computer files, a table view is the representation of a table in computer memory. Tables are dbf, csv, excel files, a table view is created in the contents pane when a table is loaded. Table files remain in the computer after an ArcGIS session ends, table views cease to exist. Table views save selection information and tables do not.

how many times will the loop iterate?

Answer 12

5

Question 13

aSeq = range(5)
for anItem in aSeq:
print (f”Starting process with element {anItem}…”)
what will be the value of anItem in the third iteration?

Answer 13

2

Question 14

aSeq = range(5)
for anItem in aSeq:

will the value of aSeq change as the loop is processing?

Answer 14

no

Question 15

how many times will the loop iterate?

Answer 15

6

Question 16

aList = [134, 8, ‘X’, ‘B’, 9, aLayer]
for x in aList:

what will be the value of the variable x in the third iteration?

Answer 16

X

Question 17

aList = [134, 8, ‘X’, ‘B’, 9, aLayer]
