Using the values

Accessing the values

You actually don't need to use the return values from params._parse(). You can access the values via params itself.

from pyparam import params
params.a = 1
params._parse()

# -a 2
assert params.a.value == 2

Casting the values

If the value is a str, you can try to cast into different types using:

# assume
# params.a.value == '1'

assert params.a.int() == 1
assert params.a.float() == 1.0
assert params.a.bool() == True
assert params.a.str() == '1'

Str methods

You may also use some methods of str directly:

# assume
# params.a.value == 'abcdefg'

assert params.a + 'hij' == 'abcdefghij'
assert 'abc' in params.a
assert params.a.capitalize() == 'Abcdefg'
assert params.a.count('a') == 1
assert params.a.islower() == True
assert params.a.find('b') == 1
assert params.a.upper()  == 'ABCDEFG'
... ...

Using a different wrapper for parsed values

# python-box
from box import Box
from pyparam import params
params.a = {}

ret = params._parse(['-a.b.c.d', '1'], dict_wrapper = Box)
assert ret.a.b.c.d == 1

Using multiple params instances

You may want multiple params to store parameters from different sources, or for different uses.

from pyparam import Params

params1 = Params()
params1._loadFile('config1')
params2 = Params()
params2._loadFile('config2')
