Python allows you to put underscores in numbers for convenience. They're used to separate groups of numbers, much like commas do in non-programming. Underscores are completely ignored in numbers, much like comments. So this: x = 1_000_000. is interpreted to be the same as this: x = 1000000.
You cannot use underscore at the beginning or end of a number. You cannot use underscore adjacent to a decimal point in a floating point literal. You cannot use underscore in positions where a string of digits is expected.
Explanation: Theoretically, there is no limit on the number of underscores. 17) Java uses UTF-16 Unicode format to represent characters.
JavaObject Oriented ProgrammingProgramming. In earlier versions of Java, the underscore ("_") has used as an identifier or to create a variable name. Since Java 9, the underscore character is a reserved keyword and can't be used as an identifier or variable name.
Underscores are ignored. You can put them in to make them more readable.

It’s just a syntax convenience to separate the thousands:
$ ruby -e 'puts 1_000 + 1_000_000' #=> 1001000 If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
