Read in the first column of a CSV in python

Question

I have a CSV (mylist.csv) with 2 columns that look similar to this:

jfj840398jgg     item-2f
hd883hb2kjsd     item-9k
jie9hgtrbu43     item-12
f         


        

Answer 1

You can also use pandas here:

import pandas as pd
df = pd.read_csv(mylist.csv)

Then, getting the first column is as easy as:

matrix2 = df[df.columns[0]].as_matrix()
list2 = matrix2.tolist()

This will return only the first column in list. You might want to consider leaving the data in numpy, if you're conducting further data operation on the result you get.
