Iterating URL in a loop

Question

I need to carry out a GET request for each value that is returned in a variable. My variable is called epics and looks like this:

IN.D.VIX.MONTH2.IP,TM.D.ATHENS.DAILY.IP,KB.D.HEALTH.DAILY.IP,CS.D.EURSEK.TODAY.IP,CF.D.USDNOK.JUN.IP,CF.D.GBPJPY.MAR.IP,IR.D.IB.Month3.IP,IX.D.SUNFUN.DAILY.IP

I basically want to append one epic at a time and perform a get request e.g.

Request 1 
http://api.example.com/v1.14/member?id=IN.D.VIX.MONTH2.IP
Request 2
http://api.example.com/v1.14/member?id=TM.D.ATHENS.DAILY.IP

When I run the code below I get TypeError: range() integer end argument expected, got str.

url = "http://api.example.com/v1.14/epics?id=" + str(epics)
for i in range(epics):
    print(url)

for i in range(len(epics)) You need to call the len() function to get the length of the list when using range, this will iterate as many times that len() returns. — PacketLoss

range() takes an integer argument, however your epics variable is presumably some kind of iterable (list?). If you're looking to iterate over each of the values of epics, you can simply reference that in your for loop:

for epic in epics:
    url = "http://api.example.com/v1.14/epics?id=" + str(epic)
    print(url)
