File Opening

[Hitso]

I cannot open the file below. Both the .py file and the salesdata.csv are stored in the same directory.

This is the error :
FileNotFoundError: [Errno 2] No such file or directory: 'salesdata.csv'

Any advice ?

# Import pyplot graphing function
import matplotlib.pyplot as plt

# Open the file and read the lines
f = open('salesdata.csv','r')
salesfile = f.readlines()

check your file name/location
also, is CWD the same in which the files are located?

How do I check this ?
In my directory both the Python file and the data file are both there ?

The getcwd function in the os module will tell you what the current working directory (CWD) is (docs here):

>>> import os
>>> os.getcwd()
'/tmp'

---

It's not really about where your program is, it's more about where you're running it from (i.e. its CWD). If you're still stuck, then showing the CWD and path to the file should help us help you.

This is the code, and the error message when running it.
runcell(0, 'C:/Users/heetesh.j.bhoola/Desktop/PYTHON FILES/untitled2.py')
Traceback (most recent call last):

File "C:\Users\heetesh.j.bhoola\Desktop\PYTHON FILES\untitled2.py", line 14, in <module>
f = open('salesdata.csv','r')

FileNotFoundError: [Errno 2] No such file or directory: 'salesdata.csv'

# Import pyplot graphing function
import matplotlib.pyplot as plt

# Open the file and read the lines
f = open('salesdata.csv','r')
salesfile = f.readlines()


import os
os.getcwd()
'/tmp'

try

import os
import sys

cwd = os.path.dirname(sys.argv[0])
    
with open(f'{cwd}/salesdata.csv','r') as f:
    salesfile = f.readlines()
    print(salesfile)

Thanks.
I ran the code, get the following error. I'm really lost on this seemingly simple task.

runcell(0, 'C:/Users/heetesh.j.bhoola/Desktop/PYTHON FILES/untitled2.py')
Traceback (most recent call last):

File "C:\Users\heetesh.j.bhoola\Desktop\PYTHON FILES\untitled2.py", line 9, in <module>
cwd = os.path.dirname(sys.argv[0])

NameError: name 'sys' is not defined

[buran]

you need to import sys, as shown by @Alex_Erfurt

I have also had some issues, try copying your csv file into another directory and then only after that copying your .py file into the same directory.

Thanks all for your assistance.
This is still not solved, and have tried all suggestions.
