str2type 0.4.1

Convert a string representation of an int, float, None, True, False, or JSON to its native type. For None, True, and False, case is irrelevant.

Convert the string representation of a Python type to its native type.

Why?

When building commandline utilities the syntax --arg key=val is useful, especially when key and val will be used as Class(key=val) internally. This module was built specifically to be used with the CLI framework click, and the included extensions play nicely, but the str2type.str2type() function can be used elsewhere.

Examples

See the examples directory for click integration examples. Everything else is primarily handled by a single function:

>>> from str2type import str2type
>>> print(str2type("1.23"))
1.23
>>> print(str2type("1.")
1.0
>>> print(str2type(".2"))
0.2
>>> print(str2type("None"))
None
>>> print(str2type('String'))
'String'
