So I have a script that opens and reads a csv file. I'm trying to take what I get from the csv file, do some math, and store the updated values in a dictionary; only I can't get that last step to work.
import csv
d = {}
reader = csv.reader(open('file.csv', 'rb'))
for row in reader:
name = row[0]
date = row[1]
x = row[2]
y = row[3]
z = x + y
The dictionary I'd like to store the values in would look like:
d = {
'Jim': [
{'2008-04-19':17},
{'2008-04-17':15}
],
'Bob': [
{'2008-02-11':18},
{'2008-01-12':22}
]
}
It seems like I couldn't use d.update() because that would just overwrite whatever is already in d. And there isn't an append() function for dictionaries, which I would think would make this a lot easier. So, help me.
