Python：如何将CSV文件中的某些信息附加到数组中

Question

如何将CSV文件的第一列中的所有值附加到数组上。

鉴于csv

Anas,5/1/2015,2.875
Jack,5/1/2015,33.925
Conk,5/1/2015,136.85

数组将是

['Anas', 'Jack', 'Conk']

如果我需要一个带有第二列值的单独数组，它也会是相同的代码吗？

这就是我试过的

for line in file:
    Data=line.split(",")
    FromFile=Data[0]
    questions=FromFile.append(line)

Answer 1

with open("example.csv") as f:
    allData = [line.strip().split(",") for line in f]

    firstColumn  = [data[0] for data in allData]
    secondColumn = [data[1] for data in allData]
    thirdColumn  = [data[2] for data in allData]
