How to Fix \"FileNotFoundError: No Such File or Directory\" When Opening a CSV File?

Troubleshooting FileNotFoundError: No Such File or Directory

Issue: When attempting to open a CSV file, Python fails to locate the file, resulting in a "FileNotFoundError: [Errno 2] No such file or directory" error.

Code:

<code class="python">import csv

with open('address.csv','r') as f:
    reader = csv.reader(f)
    for row in reader:
        print row</code>

Solution:

The error typically occurs when Python cannot find the specified file in the current working directory. To resolve this, you can provide an explicit path to the file using either a relative or absolute path.

Relative Path:

A relative path specifies the location of the file relative to the current working directory. To use a relative path, simply include the file name without the complete directory path:

<code class="python">import csv

with open('address.csv','r') as f:
    # ...</code>

Absolute Path:

An absolute path provides the complete directory path to the file, regardless of the current working directory. To use an absolute path, prefix the file name with the complete path:

<code class="python">import os

cwd = os.getcwd()  # Get the current working directory
path = os.path.join(cwd, 'address.csv')  # Construct the absolute path
f = open(path, 'r')
# ...</code>

Remember to verify that the file exists at the specified path and that you have the necessary permissions to open it.
