How to enumerate and sort a list from a text document in Python
I am trying to enumerate a list in python using a text document. I have read-in the document but can't seem to sort or enumerate them. The goal is to call in the time that they finished the race, sort them, and then enumerate them by order of finish.
The output is always:
(['18:44'], generator object enumerate at 0x0000000003143630)
I am not sure why it is saying "generator object enumerate at 0x0000000003143630" or how to enumerate the sorted list.
def get_sec(time_str):
h, m = time_str.split(':')
return int(h) * 3600 + int(m) * 60
def enumerate(sequence, start=0):
n = start
for elem in sequence:
yield n, elem
n += 1
with open("Race_Results_Sample.txt", "r")as myList:
myList = myList.read()
myList = [l.split(",") for l in myList.splitlines()]
myList = sorted(myList, key=lambda kv: kv[1])
for line in myList:
num, last, org, time = line
place =
place.append(time)
placenum = enumerate(sorted(place))
print(place, placenum)
for line in myList:
num, last, org, time = line
new_time = get_sec(time)
mile = round((((new_time/ 3.10686)/60)/60), 3)
mile = str(mile)
print ('{:<20s}{:<5s}{:<5s}{:<7s}{:<10s}'.format(last, num, org, time, mile))
The first "for line in myList" is just a test to see how it works on its own. I will eventually place it in the second "for line in myList" section to clean up the code a bit more. Thanks in advance for your help.
THIS IS THE CURRENT OUTPUT

enumerate does not return a list, but a special kind of generator. Write
placenum = list(enumerate(sorted(place)))
and your program's behavior will make more sense. Alternately you can use (consume) a call to enumerate() directly in a for loop, as if it was a list. E.g.
for rank, value in enumerate(sorted(place)):
print(rank, value)
