+
+After running the command
+
+`go-flows run features pcap2flows.json export csv Ex2flows_team13.csv source libpcap Ex2_team13.pcap`
+
+we get the file `Ex2flows_team13.csv`.
+
+The following python script quickly extracts the 
+percentage of sources communicating with one or more than ten destinations:
+
+```python
+import pandas as pd
+
+df = pd.read_csv(r'../data/Ex2flows_team13.csv')
+
+dataLength = len(df)
+
+singleDestinationFilter = df['distinct(destinationIPAddress)'] == 1
+moreThan10DestinationsFilter = df['distinct(destinationIPAddress)'] > 10
+
+percentageOfSingleDst = len(df[singleDestinationFilter]) / dataLength * 100
+percentageOfMoreThan10Dst = len(df[moreThan10DestinationsFilter]) / dataLength * 100
+
+print("Single Destination: {} %".format(round(percentageOfSingleDst, 3)))
+print("More than 10 destinations: {} %".format(round(percentageOfMoreThan10Dst, 3)))
+```
+
+Output:
+
+```
+Length of dataset: 209434
+Single Destination: 94.901 %
+More than 10 destinations: 0.796 %
