How to get three exported png files using the for loop in the code below?
-1
the code below is performing the following actions:
- plotting xy coordinates from csv
- creating shapefile
- loading shapefile in ArcMap
- labeling map features
- Selecting specific map features
- Zooming in on selected features
- Exporting a PNG file
- Repeating the last three steps for two other sets of features
the code runs with no error but I am not getting three PNG files, one for each set of features (defined as sql_1, sql_2, sql_3 in code). Instead I am getting one exported PNG file of the last set of features I want to export (sql_3)
What can I do get three exported png files using the for loop in the code below?

I think you need to change the name of the export to coincide with the sql statement, otherwise you will just overwrite the initial output.
number = 1
for x in SQL_List:
output = 'example{}.png'.format(number) # this will add the number to the file name
# Select Features & Zoom
nycbrg = arcpy.mapping.ListLayers(mxd)[0]
arcpy.SelectLayerByAttribute_management(nycbrg, "NEW_SELECTION", x)
df.zoomToSelectedFeatures()
mxd.save()
# Declare Variable of Where to Save Map Export
Make_Export = 'C:UsersHector HernandezDocumentsGitHubpratt-savi-810-2018-10projectshhernandez project{}'.format(output)
# Export Map
arcpy.mapping.ExportToPNG(mxd, Make_Export, df)
number += 1 # this will increment the output number for the filename

thank you @Hotpepper. I got an error message that number variable was not defined. so i defined it as number = 1. the code worked but still just gave me the export of sql_3 (last map export) and not the first two. any other thoughts?
