# 2. Text Searching
In Notepad, text searching is one of the functions we often need to use. With the search and replace function, we can quickly locate text, perform editing and management. The following will detail the text search function of Notepad.

#### 2.1 Using Keywords for Text Searching
In Notepad, we can search for text through simple shortcut key operations. This usually involves the following steps:

2. Enter the keyword you want to search for in the search box.
3. Click the "Find Next" button to sequentially search for all matching text.

#### 2.2 Application of Search and Replace Function
Notepad also provides text search and replace functions, allowing us to quickly replace content within the text. Below is an example table showing the search and replace function:

| Operation | Shortcut Key |
|------------------------------|--------------------|
| Open Search Box | `Ctrl + F` |

In Notepad, the search and replace function is very convenient and can help us quickly modify text content.

#### 2.3 Code Example: Using Python to Search for Specific Content in Text

# Example: search for lines containing a keyword in a text file and print them
def search_text(file_path, keyword):
    with open(file_path, 'r') as ***
        ***
            ***
                ***"Line {line_number}: {line.strip()}")

# Call the function to search
search_text('sample.txt', 'Notepad')

The above code example demonstrates how to use Python to search for lines containing specific keywords in a text file and print out the line numbers and contents of the lines containing the keywords.

#### 2.4 Flowchart Example: Search and Replace Text Process

    B --> C{Matching Result?}
    C -- Yes --> D[Replace Keyword]
    C -- No --> E[End Search]
    D --> B
    E --> F[Save File]

This is an introduction to the text search function of Notepad. The flexible use of the search and replace function can improve our efficiency in text processing.
