You can also specify text alignment using the greater than operator:>. For example, the expression{:>3.2f}would align the text three spaces to the right, as well as specify a float number with two decimal places. Conclusion In this article, I included an extensive guide of string data typ...

'{:4d}'.format(42) Output 42 Again similar to truncating strings the precision for floating point numbers limits the number of positions after the decimal point. For floating points the padding value represents the length of the complete output. In the example below we want our output to have...
Floating-point numbers symbolize the real numbers that are written with a decimal point dividing the integer and fractional parts. Floating-point numbers may also come with scientific notation with E or e, indicating the power of 10. Example: 5.6e2 that means 5.6 * 102. I = 2.5 J = 7.5e...
