Python dictionary in to html table

Python dictionary in to html table

To convert a Python dictionary into an HTML table, you can use string formatting to construct the HTML code. Here's a step-by-step example of how to do this:

# Sample dictionary data = { 'Name': ['Alice', 'Bob', 'Charlie'], 'Age': [25, 32, 19], 'Country': ['USA', 'Canada', 'UK'] } # Create an HTML string for the table html_table = '<table border="1">\n' html_table += '<tr>\n' # Add table headers for key in data.keys(): html_table += f'<th>{key}</th>\n' html_table += '</tr>\n' # Add table rows for i in range(len(data['Name'])): html_table += '<tr>\n' for key, values in data.items(): html_table += f'<td>{values[i]}</td>\n' html_table += '</tr>\n' html_table += '</table>' # Save the HTML table to a file or display it with open('table.html', 'w') as file: file.write(html_table) # You can also display the HTML table in a Jupyter Notebook using IPython display from IPython.display import HTML display(HTML(html_table))

In this example:

  1. We have a sample dictionary data with three keys ('Name', 'Age', and 'Country').

  2. We construct an HTML table by building an HTML string. We iterate through the keys to create table headers and then iterate through the values to create table rows.

  3. We use string formatting to insert the values from the dictionary into the HTML table structure.

  4. You can save the resulting HTML table to a file or display it in a Jupyter Notebook using IPython's display function.

This code generates a basic HTML table from the dictionary data. You can further customize the HTML table by adding CSS styles or additional HTML attributes based on your needs.
