Reading and Writing Long Numbers

Code is more often read than it is written, and reading a big/long number within other text can be a challenge. Here are two approaches to making numbers more readable:

1. Using underscores in Numeric Literals. 1_000_000 is more readable than 1000000, and 10_100_201_330 is easier to scan than 10100201330. For more information, see PEP-0515.

2. Using exponential notation or scientific notation. The e (or E) character followed by an integer represents the power of 10 by which the number preceding the e should be multiplied (ie: 1e6, 1 is multiplied by 10 raised to the power of 6, which equals 1000000). For more details, check out this reference on scientific notation.
