我正在为股票拉1分钟的历史栏,数据如下:
'2018-06-11 09:31:00,968.250,965.000,968.000,965.250,17220,1160\n2018-06-11
09:32:00,965.250,964.250,965.250,964.750,17872,611\n2018-06-11
09:33:00,965.000,963.250,965.000,963.500,18851,547\n'
这是一个字符串,其中每一行由换行符分隔,每个字段用逗号分隔。当我使用print()函数时它看起来很好但我想将它转换为pandas数据帧。我感谢任何帮助。
答案 0 :(得分:3)
将字符串送入pandas.read_csv
:
import pandas as pd
from io import StringIO
mystr = StringIO("""2018-06-11 09:31:00,968.250,965.000,968.000,965.250,17220,1160\n2018-06-11 09:32:00,965.250,964.250,965.250,964.750,17872,611\n2018-06-11 09:33:00,965.000,963.250,965.000,963.500,18851,547\n""")
df = pd.read_csv(mystr, index_col=0, header=None)
df.index = pd.to_datetime(df.index)
print(df)
