你只需要转换csv。读者dict:

~ >> cat > 1.csv
key1, value1
key2, value2
key2, value22
key3, value3

~ >> cat > d.py
import csv
with open('1.csv') as f:
    d = dict(filter(None, csv.reader(f)))

print(d)

~ >> python d.py
{'key3': ' value3', 'key2': ' value22', 'key1': ' value1'}

如果你有:

csv中只有一个键和一个作为键的值 不想导入其他包 想要一次创造字典

这样做:

mydict = {y[0]: y[1] for y in [x.split(",") for x in open('file.csv').read().split('\n') if x]}

它能做什么?

它使用列表推导式来分割行，最后一个“if x”用于忽略空行(通常在末尾)，然后使用字典推导式将空行解压缩到字典中。

也可以使用numpy。

from numpy import loadtxt
key_value = loadtxt("filename.csv", delimiter=",")
mydict = { k:v for k,v in key_value }

假设你有一个这样结构的CSV:

"a","b"
1,2
3,4
5,6

你希望输出是:

[{'a': '1', ' "b"': '2'}, {'a': '3', ' "b"': '4'}, {'a': '5', ' "b"': '6'}]

zip函数(还没有提到)非常简单，而且非常有用。

def read_csv(filename):
    with open(filename) as f:
        file_data=csv.reader(f)
        headers=next(file_data)
        return [dict(zip(headers,i)) for i in file_data]

如果你更喜欢熊猫，它也可以很好地做到这一点:

import pandas as pd
def read_csv(filename):
    return pd.read_csv(filename).to_dict('records')

我建议添加if行，以防文件末尾有空行

import csv
with open('coors.csv', mode='r') as infile:
    reader = csv.reader(infile)
    with open('coors_new.csv', mode='w') as outfile:
        writer = csv.writer(outfile)
        mydict = dict(row[:2] for row in reader if row)

你可以用这个，它很酷:

import dataconverters.commas as commas
filename = 'test.csv'
with open(filename) as f:
      records, metadata = commas.parse(f)
      for row in records:
            print 'this is row in dictionary:'+rowenter code here
