Read csv with different structures

example1

ticker4,value4

to read this type of csv file, use

read_df(path='path',file_pattern='filename')

example2

stkid,open,high,low,close
ticker1,o1,h1,l1,c1
ticker2,o2,h2,l2,c2
ticker3,o3,h3,l3,c3

to read open, use

Open=read_df(path='path',file_pattern='filename',dat_col='open')

to read open and close, use

Open,Close=read_df(path='path',file_pattern='filename',dat_col=['open','close'])

to return a multi index dataframe, use

Price=read_mdf(path='path',file_pattern='filename',dat_col=['open','close'])

Write

dataframe example

            ticker1     ticker2     ticker3
20180101     10.32       20.22        12.35
20180102      NaN        20.10        13.31
20180105      NaN        20.10        12.12

use write_df to write data of each date to one csv file

dictionary example

each value in the dictionary should be a dataframe and be like the example showed above

write_factors(path='path',file_pattern='filename',**dictionary)

Notice

Default reading trading calendar is Chinese market trading calendar, to change the calendar use dt_range option to input all dates.
