Answer 1

假设您的csv位于名为data.csv的文件中，并且您在同一目录中运行该脚本。

然后你会做类似的事情：

import pandas as pd              # bring in pandas

df = pd.read_csv('data.csv')     # load data
print(df[df['user'] == 'mike'])  # add a mask for mike and print row

Answer 2

两种方式，首先是Python：

struct

现在有了Bash：

import csv

with open('file.csv', 'r') as fin:
    reader = csv.reader(fin)
    for line in reader:
        if line[0] == 'mike':
            print line[3]
            break
