将csv文件转换为词典列表

Question

我有一个csv文件

col1, col2, col3
1, 2, 3
4, 5, 6

我想从这个csv创建一个字典列表.

输出为:

a= [{'col1':1, 'col2':2, 'col3':3}, {'col1':4, 'col2':5, 'col3':6}]

我怎样才能做到这一点？

Answer 1

用途csv.DictReader:

import csv

with open('test.csv') as f:
    a = [{k: int(v) for k, v in row.items()}
        for row in csv.DictReader(f, skipinitialspace=True)]

Answer 2

另一个更简单的答案：

    import csv
    with open("configure_column_mapping_logic.csv", "r") as f:
        reader = csv.DictReader(f)
        a = list(reader)
        print a

Answer 3

使用csv模块和列表理解:

import csv
with open('foo.csv') as f:
    reader = csv.reader(f, skipinitialspace=True)
    header = next(reader)
    a = [dict(zip(header, map(int, row))) for row in reader]
print a    

输出:

[{'col3': 3, 'col2': 2, 'col1': 1}, {'col3': 6, 'col2': 5, 'col1': 4}]

Answer 4

很长时间后才在这里回答，因为我没有看到任何更新/相关的答案。

df = pd.read_csv('Your csv file path')  
data = df.to_dict('records')
print( data )
