Lists and Conditional Statements

You can use a list with the for statement, to process each element of the list in turn:

segmentlist = ["MSH", "EVN", "PID", "NK1", "PV1"]
for segment in segmentlist:
	print segment
# prints each segment name on its own line

You can also use a list with an if statement:

segmentlist = ["MSH", "EVN", "PID", "NK1", "PV1"]
segment = "PID"
if segment in segmentlist:
	print segment, "is a segment in the list"
if segment not in segmentlist:
	print segment, "is not a segment in the list"

This is a convenient way to determine whether a value matches, or does not match, one of a number of acceptable alternatives.
