I am new to Python and I am trying to check for nulls in the csv I am processing. I am using a DictReader object with key pair values. I am using the key pair values in the for loop to print out the information(kml in this instance).
I go to run the program and it is not liking my variable assignment. Here is the error I am receiving.
File "./csvtokml3.py", line 31
Latvariable = str(row["lat_degrees"]),Longvariable = str(row["lon_degrees"])
SyntaxError: can't assign to function call
Here is the code for the program.
#!/usr/bin/python
#
#
#
import csv
#Input the file name.
fname = raw_input("Enter file name WITHOUT extension: ")
data = csv.DictReader(open(fname + '.csv'), delimiter = ',')
#Open the file to be written.
f = open('csv2kml.kml', 'w')
#Writing the kml file.
f.write("<?xml version='1.0' encoding='UTF-8'?>\n")
f.write("<kml xmlns='http://www.opengis.net/kml/2.'>\n")
f.write("<Document>\n")
f.write(" <name>" + fname + '.kml' +"</name>\n")
for row in data:
f.write(" <Placemark>\n")
f.write(" <name>" + str(row["station"]) + "</name>\n")
### f.write(" <description>" + str(row[0]) + "</description>\n")
f.write(" <Point>\n")
#Check for nulls for lat and long
Latvariable = str(row["lat_degrees"]), Longvariable = str(row["lon_degrees"])
if Latvariable !=null and Longvariable !=null:
f.write(" <coordinates>" + str(row["lat_degrees"]) + "," + str(row["lon_degrees"]) + "</coordinates>\n")
f.write(" </Point>\n")
f.write(" </Placemark>\n")
f.write("</Document>\n")
f.write("</kml>\n")
f.close()
print "File Created. "
print "Press ENTER to exit. "
raw_input()
Your syntax is incorrect, you wanted:
Latvariable, Longvariable = str(row["lat_degrees"]), str(row["lon_degrees"])
instead to assign multiple values to multiple names. Alternatively, put the two statements on separate lines:
Latvariable = str(row["lat_degrees"])
Longvariable = str(row["lon_degrees"])
You cannot combine multiple assignment statements with commas like you tried; that works in JavaScript but not in Python.
