    style='style1', # default: 'style', 'style1', 'style2', 'style3', 'custom'
    format='pdf'    # default: 'pdf', 'docx', 'pptx', 'html'
)
with open('output.pdf', 'wb') as f:
    f.write(output)

# Method 2: Direct to file (returns None)
exportmd.to(
    markdown=markdown_content,
    format='pdf',
    output_file='output.pdf'  # File is saved directly
)

Parameters:

• markdown: Input markdown text
• format: Output format ('pdf', 'docx', 'pptx', 'html')

Code Block Support

Use standard markdown code blocks with Python:

# Print statements
print("Hello, World!")

# Matplotlib
import matplotlib.pyplot as plt
plt.plot([1, 2, 3], [1, 2, 3])
plt.show()

# Plotly
import plotly.express as px
df = px.data.iris()
fig = px.scatter(df, x="sepal_width", y="sepal_length")

# Seaborn
import seaborn as sns
tips = sns.load_dataset('tips')
sns.boxplot(data=tips, x='day', y='total_bill')
plt.show()

Styling Options
