statistics writing data to excel file python
Another experiment inspired by Statistics class.
Excel has the tools to do this, but I'd like to find a way to do it with python and command prompt / terminal.
I don't explain much in this one, but I plan to elaborate and make it do more. But for now, I got to nappy nap before work. For those who have seen the prior 'write to excel' experiments and followed along, this shouldn't need too much explaining.
Here's the text for method info, which should display if a user types 'help' or '??' when a conflict occurs in data input:
format:
|__column1___ |__column2__|__column3__| ....
| row1 data | row1 data | row1 data | ....
| row2 data | row2 data | row2 data | ....
| .... | ..... | ...... | ....\n
This project will ask for information to write to your excel file.
The data it will ask for ( in order ):
file_name: the program will add the file extension for you.
number of columns in table (max 20)
name of columns or None-for no names
the number of rows in the columns (max 50)
the data for the rows (format: 1.1, 2.2, 3.3, 49.0 or: lost, found, misplaced, destroyed)\n
type help or ?? in prompt at any time to repeat this information
THE CODE:
--start code block--
--end code block--
