使用标题词作为键从.CSV文件创建词典列表

Question

我正在尝试从我的.csv文件创建一个字典列表.我想让文件的第一行成为字典键,并在列的下面对应它们的值.这已经使用.txt文件成功完成,它完美地运行.当我尝试使用.csv格式时,我遇到了能够调用特定密钥的问题,因此我认为它无法正常工作.

newqstars = [meteor['M_P'] for meteor in kept2]

>>>KeyError: 'M_P'

我一直在尝试其他方法,如DictReader()和csv.reader(),但它们不起作用所以我只是问我如何修改下面的内容以便能够处理.csv

def example_05(filename):


    with open(filename,'r') as file : data = file.readlines()
    header, data = data[0].split(), data[1:] 

    #................ convert each line to a dict, using header 
    # words as keys

    global kept2 
    kept2 = []

    for line in data :
        line = [to_float(term) for term in line.split()]
        kept2.append( dict( zip(header, line) ) )

if __name__ == '__main__' :

    example_05('Geminids.csv')

Answer 1

DictReader是这里的方式:

import csv

with open('summ.csv') as csvfile:
    reader = csv.DictReader(csvfile)
    kept2 = [row for row in reader]
