Error: Module Not Defined in Python
You may encounter warnings like:
- "
ChromePdfRenderer" is not defined - "
PdfCssMediaType" is not defined - "
FitToPaperModes" is not defined
The above warnings can be ignored. Since IronPDF for Python utilizes IronPDF C#, these features are implemented in .NET 6.0. As a result, the relevant class definitions might not be directly viewable or defined within the Python environment.
Below is an example of how you might encounter and handle such a situation in Python when using the IronPDF library.
# Importing the IronPDF module. This is assumed to be a hypothetical Python wrapper for IronPDF C# library.
# In practice, you might use a Python package manager to install and import the necessary module.
from ironpdf import ChromePdfRenderer, PdfCssMediaType, FitToPaperModes
# Example function using IronPDF components to illustrate usage
def generate_pdf():
try:
# Create a new PDF renderer
renderer = ChromePdfRenderer()
# Define options or configurations for the renderer
renderer.css_media_type = PdfCssMediaType.PRINT
renderer.fit_to_paper_mode = FitToPaperModes.FIT
# Assume we have HTML content to convert to PDF
html_content = "<h1>Hello, World!</h1>"
# Render the HTML content to PDF
pdf_document = renderer.render_html_as_pdf(html_content)
# Save the PDF document to a file
pdf_document.save_as("output.pdf")
except Exception as e:
# Log and handle any exceptions that occur during PDF generation
print(f"An error occurred: {e}")
# Execute the function to generate a PDF
generate_pdf()# Importing the IronPDF module. This is assumed to be a hypothetical Python wrapper for IronPDF C# library.
# In practice, you might use a Python package manager to install and import the necessary module.
from ironpdf import ChromePdfRenderer, PdfCssMediaType, FitToPaperModes
# Example function using IronPDF components to illustrate usage
def generate_pdf():
try:
# Create a new PDF renderer
renderer = ChromePdfRenderer()
# Define options or configurations for the renderer
renderer.css_media_type = PdfCssMediaType.PRINT
renderer.fit_to_paper_mode = FitToPaperModes.FIT
# Assume we have HTML content to convert to PDF
html_content = "<h1>Hello, World!</h1>"
# Render the HTML content to PDF
pdf_document = renderer.render_html_as_pdf(html_content)
# Save the PDF document to a file
pdf_document.save_as("output.pdf")
except Exception as e:

print(f"An error occurred: {e}")
# Execute the function to generate a PDF

Explanation:
- Import Statements: The code assumes the existence of a Python wrapper or module for IronPDF (
ironpdf). Real-world implementation would require the actual module installation via a package manager. - Error Handling: The function
generate_pdf()is equipped with a try-except block to catch and handle exceptions that may occur due to undefined classes in Python. - PDF Rendering: The use of
ChromePdfRendererand other classes illustrates how you would typically set options and render PDF documents if the Python interface were accessible.
Note: The provided code is hypothetical and intended for illustrative purposes, assuming the existence of a Python wrapper for IronPDF. Actual implementation details may vary based on library support and integration with .NET components.
