我已经在Python中创建了一个字典数据类型:
selecteddatas = random.sample(numbers, 100)
for data in selecteddatas:
calls = random.choice(range(600))
a[data] = {'time_stamp': str_now, 'calls': calls}
,并且我正在尝试将其导出到csv文件,但无法正常工作。谁能建议我该怎么做。

具有相同键的字典列表可以轻松转换为pandas DataFrame。然后可以将它们轻松转换为csv。
import pandas as pd
pd.DataFrame(a).to_csv(filepath,index=False)

在没有pandas
的情况下,使用csv.DictWriter
:
import random, csv, datetime
selecteddatas = random.sample(list(range(100)), 100)
a = {}
for data in selecteddatas:
calls = random.choice(range(600))
a[data] = {'time_stamp': datetime.datetime.now(), 'calls': calls}
with open('data.csv', 'w', newline='') as csvfile:
writer = csv.DictWriter(csvfile, fieldnames=['time_stamp', 'calls'])
writer.writeheader()
for k in a.keys():
writer.writerow(a[k])
data.csv包含:
time_stamp,calls
