6.2.2 Converting strings to numbers
Strings which contain numerical data can be converted to numbers by passing them to the object types.number(), as in the examples:
pyxplot> print types.number("23")
23
pyxplot> print types.number("1610 1643 1715 1774".split()[2])
1715
pyxplot> print types.number("978-0230200951"[4:])
230200951
It is an error to try to convert a string to a number if it does not contain a correctly-formatted number:
|
types.number("this is not a number") |
