Pandas' syntax for mapping index values to relevant data is the same syntax Python uses to map dictionary keys to values. For example, if s is a Series, s['a'] will return the data point at index a. Unlike dictionary keys, index values are not guaranteed to be unique. If a Series uses the index value a for multiple data points, then s['a'] will ...
The spreadsheet programming paradigm is where you have pages of rows and columns to make up a (near) infinite table of cells. Some cells are input cells where the user can input numbers or other data. Other cells have a formula in them such that their value can be calculated based on the contents of other cells.
In computer science, a lookup table (LUT) is an array that replaces runtime computation with a simpler array indexing operation, in a process termed as direct addressing.The savings in processing time can be significant, because retrieving a value from memory is often faster than carrying out an "expensive" computation or input/output operation.

Farmers have a legal option for hiring labor with the H-2A visa program, which allows employers to bring in an unlimited number of seasonal workers if they can show there are not enough U.S ...
A Queens public high-school teacher created a creepy “escape room” where he allegedly sexually abused a female student, according to a troubling new report.
Index mapping (or direct addressing, or a trivial hash function) in computer science describes using an array, in which each position corresponds to a key in the universe of possible values. [1] The technique is most effective when the universe of keys is reasonably small, such that allocating an array with one position for every possible key ...
MOSCOW (Reuters) -Russian President Vladimir Putin denied on Thursday that Russia's nine-year intervention in Syria had been a failure, but expressed concern about Israel's military operations ...
For example, if an array of integers is stored in a region of the computer's memory starting at the memory cell with address 3000 (the base address), and each integer occupies four cells (bytes), then the elements of this array are at memory locations 0x3000, 0x3004, 0x3008, …, 0x3000 + 4(n − 1) (note the zero-based numbering).
