Python - Printing a dictionary as a horizontal table with headers

Python - Printing a dictionary as a horizontal table with headers

Printing a dictionary as a horizontal table with headers can be achieved using Python's string formatting capabilities. Here's a step-by-step approach to achieve this:

Example Scenario

Let's assume you have a dictionary representing data and you want to print it as a horizontal table with headers.

data = { 'Name': 'John Doe', 'Age': 30, 'City': 'New York', 'Occupation': 'Engineer' }

Printing as a Horizontal Table

To print the dictionary as a horizontal table with headers:

def print_horizontal_table(data): headers = list(data.keys()) values = list(data.values()) # Calculate maximum width for formatting max_key_length = max(len(str(key)) for key in headers) max_value_length = max(len(str(value)) for value in values) max_length = max(max_key_length, max_value_length) # Print headers for header in headers: print(f"{header:{max_length}}", end=' ') print() # Newline after headers # Print values for value in values: print(f"{value:{max_length}}", end=' ') print() # Final newline # Call the function with your dictionary print_horizontal_table(data)

Output

Name Age City Occupation John Doe 30 New York Engineer

Explanation

  1. Formatting Headers and Values:

    • Convert the dictionary keys (headers) and values (values) into lists.
    • Calculate the maximum length needed for formatting (max_length) based on the longest key or value.

  2. Printing Headers:

    • Iterate through headers and print each header with a formatted width (max_length).

  3. Printing Values:

    • Iterate through values and print each value with the same formatted width (max_length).

  4. Formatting Using f-strings:

    • Use f-strings for formatting, ensuring that each field is aligned properly using :{max_length}.

This approach ensures that both headers and corresponding values are printed in a horizontally aligned table format. Adjust the data dictionary according to your actual dataset. This method assumes that all values can be represented as strings; if not, additional type checking and conversion may be necessary.

  4. Python display dictionary as horizontal table

    Description: Query about displaying a dictionary as a horizontal table for better readability.

    Code Example:

    def display_dict_table(dictionary): headers = list(dictionary.keys()) values = list(dictionary.values()) max_lengths = [max(map(len, map(str, col))) for col in values] # Print headers for i, header in enumerate(headers): print(f'{header:<{max_lengths[i]}}', end=' | ') print() # Print values for i in range(len(values[0])): for j in range(len(headers)): print(f'{str(values[j][i]):<{max_lengths[j]}}', end=' | ') print() # Example usage: data = { 'Name': ['Alice', 'Bob', 'Charlie'], 'Age': [25, 30, 35], 'City': ['New York', 'Los Angeles', 'Chicago'] } display_dict_table(data)

    Explanation: The function display_dict_table prints a dictionary where each key's values are displayed in columns with headers, ensuring alignment based on maximum value length.
