Help With Parallel Arrays

[snippsat]

Any suggestions on how to make it more neat, so that the index of each array gets paired up in a column?

A dictionary is a natural solution for this.

λ ptpython
>>> months = ['January', 'Febuary', 'March',  'April', 'May', 'June',
...           'July', 'August', 'September', 'October', 'November', 'December']
... rain = [40, 45, 30, 20, 15, 12, 13, 10, 17, 19, 20, 35]

>>> record = dict(zip(months, rain))
>>> record
{'January': 40,
 'Febuary': 45,
 'March': 30,
 'April': 20,
 'May': 15,
 'June': 12,
 'July': 13,
 'August': 10,
 'September': 17,
 'October': 19,
 'November': 20,
 'December': 35}

>>> # Then look up is easy
>>> record['March']
30

>>> record.get('May', 'Not in record')
15
>>> record.get('holliday', 'Not in record')
'Not in record'
