尝试此代码

import csv

    with open ('CityPop.csv', 'r') as f:
        reader = csv.reader(f, delimiter=",")
        #read_data = f.read()
        for line in reader:
            print(line)
            #record=line.strip().split(",")
    #print (read_data)

    f.close()

编辑 正如拉尔夫所说 “ f.close() 使用WITH块时不需要”
