Best way to convert csv data to dict

Question

I have csv file with following data

val1,val2,val3
1,2,3
22,23,33

So how can I convert data into dict

dict1 = { \'val1\': 1         


        

Answer 1

The cool thing with using 'csv' as mentioned in other answers here is that it can be used for reading a file (the obvious use case) but also parse a regular csv formatted string.

Example for reading a csv file:

import csv
with open('my_file.csv') as f:
   for line in csv.DictReader(f, fieldnames=('val1', 'val2', 'val3')):
      print(line)

notice that you can explicitly pass the headers which you want be the keys, making it very easy to use csv files without headers.

Another use case is reading just a regular string with 'csv'

Example:

import csv
my_csv_string = 'val1, val2, val3'
my_csv_dict = next(csv.DictReader(StringIO(s), fieldnames=('key1', 'key2', 'key3')))

Anyway, csv.DictReader() is what you need..
