It actually didn't work... maybe it's because my data actually has headers... here is my basic code
import pandas as pd
from pandas import Series, DataFrame
import numpy as np
import os
import io
# import
df = pd.read_csv ('NQH7.txt', sep=', ', engine='python') #FOR ME it is importing the file with a space after the comma so having to specify that it is more than just a comma...
# Without specifying it produces column names that begin with a space and that creates issues all over the place
# clean whitespaces if they exist
df = df.applymap(lambda x: x.strip() if isinstance(x, str) else x)
# combine date and time into single column
df['datetime'] = pd.to_datetime(df.Date + ' ' + df.Time, format="%Y/%m/%d %H:%M:%S.%f")
df.set_index("datetime", inplace = True)
df = df.drop(columns=['Date', 'Time', 'Open', 'High', 'Low', 'Last', '# of Trades', 'Volume', 'OHLC Avg', 'HLC Avg',
'HL Avg', 'Bid Volume', 'Ask Volume', 'Zig Zag Mid-Point', 'Extension Lines']) # drop combined columns
When I print I get...
Output:
