pandas读取csv文件

例1 直接读取csv文件【并指定第一列为下标】

import pandas as pd

df=pd.read_csv("goog_flutends.csv", index_col=0)
print(df)

例2 通过

import pandas as pd
import io

data=""
with open("goog_flutends.csv",'r') as rf:
    data = rf.read().replace("\"","")

df=pd.read_csv(io.StringIO(data), index_col=0)
print(df)
