How can I format strings in Python to align them in straight columns?

Printing Strings with Fixed Width

When printing strings, aligning them in straight columns can enhance readability. Using format or f-strings in Python offers convenient ways to achieve this.

Using str.format()

str.format() provides a straightforward method for padding strings. Its syntax includes a placeholder {} followed by a formatting expression. For left-alignment, use < and specify the desired width. For instance:

<🎝🎝🎝>

This will print 's' with a width of 5, resulting in 's '. For right-alignment, use > instead of <.

Using f-strings (Python 3)

f-strings offer a more concise alternative to str.format(). The syntax is similar, with the formatting expression enclosed in curly braces {} prefixed with an f. For left-alignment, use &:< and specify the width.

This will produce the same output as with str.format().

Example Application

Applying these techniques to the provided code snippet:

This will align the prefixes in a straight column, while keeping the count values in the adjacent column.
