In Python: how can I fix the IsADirectoryError: [Errno 21] Is a directory: ??? this is my code: #importing sqlite and pandas import sqlite3 import pandas as pd #goal print(“Welcome! The goal of this assigment is to create a database to find meanings and synonyms for given phrases.”) #Connecting database conn = sqlite3.connect(“keilavaldez.db”) #Creating cursor to remove existing specified tables cur = conn.cursor() #creating tables cur.execute(“CREATE TABLE Synsets([SynsetID] INTEGER,[Definition] text)”) cur.execute(“CREATE TABLE Phrases([SynsetID] INTEGER,[phrase] text)”) conn.commit() #opening and reading table named “synsets” with open(“//Users//keilavaldez//Desktop//assigment 10”, ‘r’) as f: for line in f: data = line.split(‘\t’) cur.execute(‘INSERT INTO synsets (SynsetID, Definition) VALUES (?, ?)’, (data[0], data[1].strip())) #opening and reading table named “phrases” with open(“//Users//keilavaldez//Desktop//assigment 10”, ‘r’) as f: for line in f: data = line.split(‘\t’) cur.execute(‘INSERT INTO phrases (SynsetID, phrase) VALUES (?, ?)’, (data[0], data[1].strip())) #Asking the user to enter a phrase #checking if the phrase its in the database #checking phrases even if they are lower phrase = str(input(“Please enter a phrase: “)) query = ‘SELECT * FROM phrases WHERE phrase=’ + “‘”+ phrase.lower() + “‘” df = pd.read_sql_query(query, conn) #if phrase is not in database, asking the user to try again if df.empty: print(“Phrase/word not found.

The Correct Answer and Explanation is :
The IsADirectoryError: [Errno 21] Is a directory: '???' in Python occurs when an operation that expects a file encounters a directory instead. In your code, this error likely arises from attempting to open a file that is actually a directory. For instance, when reading from or writing to files, ensure that the paths specified are indeed files and not directories.
Identifying the Issue in Your Code:
In your script, the following lines open files for reading:
with open("//Users//keilavaldez//Desktop//assigment 10", 'r') as f:
for line in f:
data = line.split('\t')
cur.execute('INSERT INTO synsets (SynsetID, Definition) VALUES (?, ?)', (data[0], data[1].strip()))
and
with open("//Users//keilavaldez//Desktop//assigment 10", 'r') as f:
for line in f:
data = line.split('\t')
cur.execute('INSERT INTO phrases (SynsetID, phrase) VALUES (?, ?)', (data[0], data[1].strip()))
Both attempts open the same path, "//Users//keilavaldez//Desktop//assigment 10", for reading. If this path refers to a directory rather than a file, attempting to open it in read mode will result in an IsADirectoryError.
Steps to Resolve the Error:
- Verify the Path:
- Confirm that
"//Users//keilavaldez//Desktop//assigment 10"points to a file and not a directory. - If it’s a directory, identify the specific file within it that you intend to read.
- Specify the Correct File Path:
- Update your code to reference the exact file you want to open. For example:
with open("//Users//keilavaldez//Desktop//assigment 10//synsets_file.txt", 'r') as f:
for line in f:
data = line.split('\t')
cur.execute('INSERT INTO synsets (SynsetID, Definition) VALUES (?, ?)', (data[0], data[1].strip()))
and
with open("//Users//keilavaldez//Desktop//assigment 10//phrases_file.txt", 'r') as f:
for line in f:
data = line.split('\t')
cur.execute('INSERT INTO phrases (SynsetID, phrase) VALUES (?, ?)', (data[0], data[1].strip()))
- Handle Potential Errors:
- Implement error handling to manage cases where the file might not exist or the path is incorrect:
try:
with open("//Users//keilavaldez//Desktop//assigmant 10//synsets_file.txt", 'r') as f:
for line in f:
data = line.split('\t')
cur.execute('INSERT INTO synsets (SynsetID, Definition) VALUES (?, ?)', (data[0], data[1].strip()))
except IsADirectoryError:
print("Expected a file but found a directory. Please check the file path.")
except FileNotFoundError:
print("File not found. Please ensure the file path is correct.")
Additional Recommendations:
- Use Raw Strings for Windows Paths: If you’re working on a Windows system, consider using raw string literals for file paths to avoid issues with escape characters:
with open(r"C:\Users\keilavaldez\Desktop\assignment 10\synsets_file.txt", 'r') as f:
# Your code here
- Check for Hidden Directories: Ensure that your target directory doesn’t contain hidden directories (e.g.,
.ipynb_checkpoints) that might interfere with file operations. You can list all files, including hidden ones, using:
import os
for filename in os.listdir("//Users//keilavaldez//Desktop//assigment 10"):
print(filename)
By following these steps, you can resolve the IsADirectoryError and ensure that your code correctly interacts with the intended files.
