Converting a Jupyter notebook to a Python script without using nbconvert

I recently developed a Jupyter notebook and needed to convert it to a Python script quickly. Unfortunately, the File -> Download as -> Python (.py) option didn't work. 

This script will open a Jupyter notebook and convert it to a script:

	# Convert a Jupyter notebook to a Python script
	import json
	# Input file
	jupyter_filepath = r"my notebook.ipynb"
	# Output file
	script_filepath = r"script.py"
	# Read the Jupyter notebook
	with open(filepath) as f:
	data = json.load(f)
	# Build the lines of the script
	code = []
	for cell in data["cells"]:
	if cell["cell_type"] == "code":
	code.extend(cell["source"])
	code.append("\n\n")
	elif cell["cell_type"] == "markdown":
	markdown = ["# " + content for content in cell["source"]]
	code.extend(markdown)
	code.append("\n\n")
	# Write the script to file
	with open(script_filepath, 'w') as fp:
	for line in code:
	fp.write(line)
