Are you experiencing the frustrating DeprecationError when trying to use the createBlankPage method in PyPDF2? Don’t worry, you’re not alone! In this article, we’ll dive into the world of PyPDF2 and explore the reason behind this error, its implications, and most importantly, how to fix it.
What is DeprecationError?
A DeprecationError is a type of error that occurs when a function, method, or class is no longer supported or has been removed from a library or framework. In this case, the createBlankPage method is the culprit, and it’s been deprecated since PyPDF2 version 3.0.0.
Why was createBlankPage deprecated?
The createBlankPage method was deprecated due to its redundancy and inconsistency with the rest of the PyPDF2 API. The method was used to create a blank page in a PDF file, but it didn’t provide any additional functionality compared to the existing page creation methods.
The Solution: Use create_blank_page Instead
The fix is simple: replace createBlankPage with create_blank_page (note the underscore instead of camel case). This new method is the recommended way to create a blank page in PyPDF2.
import PyPDF2
# Create a new PDF file
pdf = PyPDF2.PdfFileWriter()
# Create a blank page using the new method
page = pdf.addBlankPage()
# Save the PDF file
with open('example.pdf', 'wb') as f:
pdf.write(f)
What’s the Difference Between createBlankPage and create_blank_page?
The main difference between the two methods is the naming convention and, of course, the fact that create_blank_page is the new and improved way to create a blank page.
| Method | Description | Availability |
|---|---|---|
| createBlankPage | Deprecated method to create a blank page | < PyPDF2 3.0.0 |
| create_blank_page | New and recommended method to create a blank page | >= PyPDF2 3.0.0 |
