By /

File handling allows you to create, read, write, update, and delete files using Python. It is one of the most important concepts for automation, data processing, and real-world Python applications. In this practice set, you’ll solve beginner-friendly file handling programs with complete solutions. Python File Handling Practice Questions with Solutions help to understand the concepts.

1. Python Program to Create and Write to a File

Difficulty: Foundation

Problem Statement

Write a Python program to create a file named student.txt and write "Welcome to CodeMantra" into it.

Python Solution

file = open("student.txt", "w")

file.write("Welcome to CodeMantra")

file.close()

print("File created successfully.")

Sample Output

File created successfully.

Explanation

The "w" mode creates a new file if it doesn’t exist and writes data to it.

Concepts Covered

  • open()
  • write()
  • close()

2. Python Program to Read Data from a File

Difficulty: Foundation

Problem Statement

Write a Python program to read the contents of student.txt.

Python Solution

file = open("student.txt", "r")

content = file.read()

print(content)

file.close()

Sample Output

Welcome to CodeMantra

Explanation

The read() method reads the complete contents of a file.

Concepts Covered

  • read()
  • Read Mode

3. Python Program to Append Data to a File

Difficulty: Foundation

Problem Statement

Write a Python program to add "Python File Handling" to the end of student.txt.

Python Solution

file = open("student.txt", "a")

file.write("\nPython File Handling")

file.close()

print("Data appended successfully.")

Sample Output

Data appended successfully.

Explanation

The "a" mode appends new data without deleting existing content.

Concepts Covered

  • Append Mode
  • write()

4. Python Program to Read a File Line by Line

Difficulty: Foundation

Problem Statement

Write a Python program to read every line of a file.

Python Solution

file = open("student.txt", "r")

for line in file:
    print(line.strip())

file.close()

Sample Output

Welcome to CodeMantra
Python File Handling

Explanation

The loop reads one line at a time from the file.

Concepts Covered

  • for Loop
  • Line-by-Line Reading

5. Python Program to Count the Number of Lines in a File

Difficulty: Practice

Problem Statement

Write a Python program to count the total number of lines in a file.

Python Solution

file = open("student.txt", "r")

count = len(file.readlines())

print("Total Lines:", count)

file.close()

Sample Output

Total Lines: 2

Explanation

The readlines() method returns all lines as a list.

Concepts Covered

  • readlines()
  • len()

6. Python Program to Count the Number of Words in a File

Difficulty: Practice

Problem Statement

Write a Python program to count the total number of words in a file.

Python Solution

file = open("student.txt", "r")

content = file.read()

words = content.split()

print("Total Words:", len(words))

file.close()

Sample Output

Total Words: 5

Explanation

The file content is split into words, and len() counts them.

Concepts Covered

  • split()
  • Word Count

7. Python Program to Check Whether a File Exists

Difficulty: Practice

Problem Statement

Write a Python program to check whether student.txt exists.

Python Solution

import os

if os.path.exists("student.txt"):
    print("File exists.")
else:
    print("File not found.")

Sample Output

File exists.

Explanation

The os.path.exists() function checks whether the specified file is available.

Concepts Covered

  • os.path.exists()

8. Python Program to Copy the Contents of One File to Another

Difficulty: Challenge

Problem Statement

Write a Python program to copy the contents of student.txt into backup.txt.

Python Solution

source = open("student.txt", "r")
destination = open("backup.txt", "w")

destination.write(source.read())

source.close()
destination.close()

print("File copied successfully.")

Sample Output

File copied successfully.

Explanation

The program reads data from one file and writes it into another.

Concepts Covered

  • File Copy
  • read()
  • write()

9. Python Program to Delete a File

Difficulty: Challenge

Problem Statement

Write a Python program to delete backup.txt.

Python Solution

import os

if os.path.exists("backup.txt"):
    os.remove("backup.txt")
    print("File deleted successfully.")
else:
    print("File not found.")

Sample Output

File deleted successfully.

Explanation

The os.remove() function deletes a file from the system.

Concepts Covered

  • os.remove()

10. Python Program to Read a File Using the with Statement

Difficulty: Challenge

Problem Statement

Write a Python program to read a file using the with statement.

Python Solution

with open("student.txt", "r") as file:
    print(file.read())

Sample Output

Welcome to CodeMantra
Python File Handling

Explanation

The with statement automatically closes the file after use, making the code cleaner and safer.

Concepts Covered

  • with
  • Context Manager
  • open()
