python homework

[MajaW]

Hi. I've been trying to finish my homework, but I don't know how to do the last part. I was given a data file called 'BP20dataset.csv' which contains three lists: patientID, age, and BP. The object of the exercise is: Write a code to identify the patients with high blood pressure (> 130 mmHg). The code should generate a list named highBPlist containing the patientID of the patients with BP > 130.
If, and enumerate statements have to be used. This is what I've come up with, but printing the highBPlist returns just []. Thanks in advance

myFile = open('BP20dataset.csv')
patientData = myFile.readlines()
myFile.close()
highBPlist = []
for BP, patientID in enumerate (highBPlist):
    if (i > 130):
        highBPlist.append(patientID)
        highBPlist = patientID.split(",")

What do you think line 8 is doing?

What do you think line 8 is doing?

It's supposed to split the values of patientID in the highBPlist with a comma

I changed it a bit, but it now returns an error: '>' not supported between instances of 'tuple' and 'int' for line 6.

myFile = open('BP20dataset.csv')
patientData = myFile.readlines()
myFile.close()
highBPlist = []
for i, patientID in enumerate (patientData):
    if (BP > 130):
        highBPlist.append(patientID)

Either that's not the code you're running, or that's not the error you get. BP isn't defined anywhere in that code.

for BP, patientID in enumerate (highBPlist):
    if (i > 130):
        highBPlist.append(patientID)
        highBPlist = patientID.split(",")

I asked about line 8 before, because it doesn't make sense. You're adding a patientID to a list... but then you erase the list and replace it with whatever patientID.split(",") returns. Why iterate over the patients, if you're not going to use any but the last one anyway?
