In Python, formatting numbers with commas is a common requirement, especially when dealing with large numbers to enhance readability. This tutorial will guide you through the process of formatting numbers with commas in Python using the format() method and the f-string method.
The format() method provides a flexible way to format strings in Python. It allows you to specify how numbers should be formatted, including adding commas for thousands separators.
In Example 1, '{:,}'.format(number) formats the integer number by adding commas as thousands separators. In Example 2, '{:,.2f}'.format(float_number) formats the float float_number by adding commas and rounding it to two decimal places.
Starting from Python 3.6, f-strings provide a concise and readable way to format strings. You can use the same format specifications as with the format() method.
In Example 3, f'{number:,}' formats the integer number using an f-string. Example 4 shows the formatting of a float using an f-string with two decimal places.
Formatting numbers with commas in Python is straightforward, thanks to the format() method and f-strings. Whether you choose the format() method or f-strings depends on your preference and the Python version you are using. Using commas for thousands separators can significantly improve the readability of large numbers in your Python code.
