### 🧩 Problem 1: Read and Display File Content

**Description:**
Write a Python program to open a text file named `info.txt` and display its contents on the screen.
If the file does not exist, display a custom message like “File not found.”

**Concepts Covered:**

* File reading using `open()`
* Handling `FileNotFoundError`

**Example:**

```
File content:
Hello, Python learners!
Welcome to file handling.

```

### 🧩 Problem 2: Write User Input to a File

**Description:**
Ask the user to input a few lines of text and write them to a file called `user_notes.txt`.
Each input line should be written on a new line.

**Concepts Covered:**

* Writing files with `"w"` mode
* Taking user input and writing multiple lines

***

### 🧩 Problem 3: Append Data to a File

**Description:**
Write a program that appends a new line `"New data added successfully."` to an existing file `log.txt`.
If the file doesn’t exist, create it.

**Concepts Covered:**

* Using `"a"` mode for appending
* Creating file if it doesn’t exist

***

### 🧩 Problem 4: Count Number of Lines in a File

**Description:**
Write a Python script to count and display the total number of lines in `data.txt`.

**Concepts Covered:**

* Iterating over file lines
* Counting items using loops

**Example:**

```
If data.txt contains:
Line 1
Line 2
Line 3

Output: 3 lines

```

***

### 🧩 Problem 5: Copy Content from One File to Another

**Description:**
Create a program that copies all content from `source.txt` to `destination.txt`.
If `source.txt` doesn’t exist, handle the error properly.

**Concepts Covered:**

* Reading and writing files
* Using `try...except` for file handling

***

### 🧩 Problem 6: Count Words in a File

**Description:**
Write a program to count the number of words in `story.txt`.
Display the total word count to the user.

**Concepts Covered:**

* File reading
* String splitting and counting

**Example:**

```
File content: "Python makes file handling easy."
Output: 5 words

```

***

### 🧩 Problem 7: Read File Using `with` Statement

**Description:**
Open a file `example.txt` using the `with` statement and display its contents line by line.
Demonstrate how Python automatically closes the file afterward.

**Concepts Covered:**

* `with open()` context manager
* Automatic file closing

***

### 🧩 Problem 8: Handle Division Error from File Input

**Description:**
You have a file `numbers.txt` containing two numbers (one per line).
Read the numbers and divide the first by the second.
If the second number is zero, display “Cannot divide by zero.”

**Concepts Covered:**

* Reading numbers from a file
* Handling `ZeroDivisionError`
