How to convert csv to dataframe in python
I have a csv file with columns A, B, C, D, and E. I want to convert to dataframe and then merge columns A, B, and C, and then merge A,B, and C with D and E.
A:
Use DataFrame.from_records for create MultiIndex Series from csv:
import pandas as pd
#create list of data
df = pd.DataFrame({'A': [1, 2, 3], 'B': [4, 5, 6],
'C': [7, 8, 9], 'D': [10, 11, 12],
'E': [13, 14, 15]})
#convert list to DataFrame with MultiIndex
df1 = pd.DataFrame.from_records(df.values.tolist(), index=df.index)
print (df1)
A B C D E
0 1 4 7 10 13
1 2 5 8 11 14
2 3 6 9 12 15
#merge by numpy array first level values:
df2 = pd.concat([df, df1], axis=1 be359ba680
