Use Python to create a comma delimited set

You can use the split function in Python to easily create a comma delimited set. If you have a divider to split upon, a script can substitute that divider with quotation marks and commas.

Follow these steps:

1. Name the set with the text you need to divide up.

>>> set1 = 'manchester england bristol england london england'

2. Use the split function with the divider designated in parentheses: >>> set1.split("england")

3. It will generate a nice comma delimited set. ['manchester ', ' bristol ', ' london ', ''] >>>

Using Python to parse data

Python scripts can be used to add returns between multiple strings that are separated with unequal blank spaces. The resulting list will have the extra spaces excised. This task is accomplished with the split function.

Working in Python 2.7, follow these steps.

1. Assign a name to the text to be parsed. In this example, we call the text 'set1'

>>> set1 = "Lopez Lee Smith"

2. Create a second set (here it's called 'names'), and then use the split function with no setting between the parentheses that follow the function name. The name of what we're parsing precedes the split function. >>> names = set1.split()

3. Python will understand a reference to a single member of a set with a plural name. Use this command: >>> for name in names:

. . . and then press return and print the reference to the set with the singular name. print name

Press return twice to get the results:

Lopez Lee Smith >>>

Working with Excel files in Python

Here's a simple guide to accessing Excel files with Python. I'm working with Python 2.7 here.

First in Windows command prompt, in the directory containing your Python scripts (see for example, C:\Python27\Scripts), run two modules:

pip install xlrd

pip install xlwt

Then in the IDLE (Python GUI) program enter the below script.

1. Import the xlrd module

>>> import xlrd

2. open the workbook

>>> book = xlrd.open_workbook("C:\FooFolder\python\BattingPost.xls")

3. designate the worksheet you want to work with

>>> sheet = book.sheet_by_name("BattingPost")

4. to pull data from a particular cell, assign a name to the cell.

>>> playerid = sheet.cell_value(2,2)

5. the value of the assigned name can be displayed by using the print command.

>>> print playerid

>>> import xlrd >>> book = xlrd.open_workbook("C:\FooFolder\python\BattingPost.xls") >>> sheet = book.sheet_by_name("BattingPost") >>> playerid = sheet.cell_value(2,2) >>> print playerid bradyst01

This is a view of the spreadsheet I pulled data from.
