How to remove 'file does not exist' error in python 35 – Artificial Intelligence

I was executing this code when i encountered this error related to file not found.
File exists in the same folder where code resides, bu still this error is not going.
Please help!

code:

import datetime as dt
import matplotlib.pyplot as plt
from matplotlib import style
from matplotlib.finance import candlestick_ohlc
import matplotlib.dates as mdates
import pandas as pd
import pandas_datareader.data as web
import numpy as np

style.use('ggplot')
df= pd.read_csv('nse2.csv', parse_dates=True, index_col=0)
df_ohlc= df['close'].resample('10D').ohlc()
df_ohlc.reset_index(inplace=True)
print(df_ohlc.head())
ax1 = plt.subplot2grid((6,1),(0,0), rowspan=5, colspan=1)
ax2 = plt.subplot2grid((6,1),(5,0), rowspan=1, colspan=1, sharex=ax1)
ax1.xaxis_date()
candlestick_ohlc(ax1,df_ohlc.values, width=2, colorup='g')
plt.show()

Here is the Error:

    My first guess is that you executed the script from in a different location other than the directory the ‘bse2.scv’ file is located.

    You need to either use the full path, or change the working directory.

    import os
os.chdir("/Users/foo/bar")

    You can see your current working directory by doing:

    os.getcwd()

    Personally I find that using the full path is always good practice.
