"ValueError：索引 DATE 无效，标题行上有 pandas.read_csv"

Question

Trying to create a dictionary with the key's being the first row of the csv file and the value's being a dictionary of {first column: corresponding column to row}:

import pandas as pd

df = pd.read_csv('~/StockMachine/data_stocks.csv', index_col=['DATE'], sep=',\s+')

data = df.to_dict()

print(data)

Answer 1

Similiar thing happened to me and in my case some readings of ['DATE'] were strings with empty spaces inside. Maybe if you would do something like:

import pandas as pd

df = pd.read_csv('~/StockMachine/data_stocks.csv', sep=',\s+')

df['DATE'] = df['DATE'].apply(lambda x: str(x.strip())).astype(str)

df.set_index('DATE', inplace=True)

print(df.head())
