python - Name Error when getting variable from another define function to be read in another define function in python3 -


i'm not sure how solve problem have encountered, how solve this?

my python code i'm using:

import plotly import plotly.plotly py import plotly.graph_objs go import plotly.figure_factory ff import numpy np datetime import date,time,datetime import pandas pd %matplotlib inline import matplotlib.pyplot plt  def readcsv(x): #def function read csv files based on input below     data = pd.read_csv(x, parse_dates=['time_stamp'], infer_datetime_format=true)     data['date'] = data.time_stamp.dt.date      data['time'] = data.time_stamp.dt.time       data['time_stamp'] = pd.to_datetime(data['time_stamp'])      print(data[1:6])  readcsv('maind.csv')  def seltimestamprange(dtstart, dtend, data):         timestamprange = (data['time_stamp'] > dtstart) & (data['time_stamp'] <= dtend)         timerange = data.loc(timestamprange)         timerange.plot(x='time_stamp', y='ac_input_current', style='-', color='black')  date_string_start = '2017-06-13 16:00:00' date_string_end = '2017-06-13 16:40:00' dtstart = datetime.strptime(date_string_start, '%y-%m-%d %h:%m:%s') dtend = datetime.strptime(date_string_end,'%y-%m-%d %h:%m:%s')  seltimestamprange(dtstart, dtend, data)

my error:

nameerror traceback (most recent call last) in () 10 #print(type(dtstart)) <-- check if dtstart has been converted datetime type 11 ---> 12 seltimestamprange(dtstart, dtend, data)

nameerror: name 'data' not defined

the data local variable available in function readcsv(x), return in function , assign result variable data, can use variable data. this:

def readcsv(x): #def function read csv files based on input below     data = pd.read_csv(x, parse_dates=['time_stamp'], infer_datetime_format=true)     data['date'] = data.time_stamp.dt.date      data['time'] = data.time_stamp.dt.time       data['time_stamp'] = pd.to_datetime(data['time_stamp'])      print(data[1:6])     return data  data = readcsv('maind.csv')
