This Python function print_book is part of a larger program where it appears to format and print information about books in a structured table format. Here's what this code snippet does:

1. Parameters:

   • book: This seems to be a data structure (e.g., dictionary, list, or object) that represents the details of a book. However, in this snippet, it is not used.
   • print_header: The parameter exists but is also not used in the provided code snippet (potentially used in a larger context).

2. Prints Header Information:

   • The first print statement creates a header row for a table-like output.
   • The header consists of column names:
     • BOOK ID
     • TITLE
     • AUTHOR
     • GENRE
     • YEAR
     • P/WEEK (potentially "price per week" or similar)
     • QTY (likely "quantity").
   • Each header is assigned a specific width using Python's formatted string syntax (:<width>). For example:
     • {'|BOOK ID':<10} reserves 10 characters for the BOOK ID column (left-aligned).
     • Likewise, other columns have designated widths (e.g., TITLE is given 56 characters, AUTHOR 30, etc.).
   • The vertical bar | is used as a delimiter between columns, simulating a table format.

3. Prints a Divider Line:

   • The second print statement outputs a line of dashes (-) to span 149 characters, representing a separator between the header and subsequent table rows containing book details.

Purpose:

This function:

• Formats and prints the header of a book data table.
• Likely meant to be followed by printing rows of book information in a consistent tabular style.

Note:

• The parameters book and print_header are defined but unused in the snippet. They might be used in the part of the function not shown or in other functions that call this one.
