Read–eval–print loop Computer programming environment The 1974 Maclisp reference manual by David A. Moon attests "Read-eval-print loop" on page 89, but does not use the acronym REPL.[4] The read function accepts an expression from the user, and parses it into a data structure in memory. For instance, the user may enter the s-expression (+ 1 2 3), which is parsed into a linked list containing four data elements.The eval function takes this internal data structure and evaluates it. The development environment then returns to the read state, creating a loop, which terminates when the program is closed. REPLs facilitate exploratory programming and debugging because the programmer can inspect the printed result before deciding what expression to provide for the next read. Because the print function outputs in the same textual format that the read function uses for input, most results are printed in a form that could be copied and pasted back into the REPL. A minimal definition is:

ipython - How can I use ptiPython with Flask-Script together? Summarize Spreadsheet Data With Excel's Array Formulas Excel Data Management Subtotals can reveal very useful management information. For example, managers might be interested to learn that sales increased by 10% last month. Array formulas provide a way by which Excel users can discover such useful information. Introducing the Data To explain the power of array formulas I'll use this database. I named each column of data with the label shown in row 1. By assigning names in this way we anchor the names in the gray border rows, rows 2 and 15. Introducing Array Formulas, Example 1 Let's begin our examination of this data by summarizing the sales for Jill and Joe. Here's the formula for the cell shown: J3: {=SUM(IF(Seller=$I3,Total,0))} Notice the braces that surround this formula. Here's the key to understanding how array formulas work: Each array formula creates temporary arrays in memory, and then the outside function returns the results from that array. Finally, the SUM function returns the sum of this temporary array: 25,680. Example 2 Example 3
