iterobj#

class iterobj(obj, func, inplace=False, twigs_only=False, verbose=False, _trace=None, _output=None, *args, **kwargs)[source]#

Iterate over an object and apply a function to each twig.

Can modify an object in-place, or return a value. See also sc.search() for a function to search through complex objects.

Parameters:

  • obj (any) – the object to iterate over

  • func (function) – the function to apply

  • inplace (bool) – whether to modify the object in place (else, collate the output of the functions)

  • twigs_only (bool) – whether to apply the function only to twigs of the object

  • verbose (bool) – whether to print progress.

  • _trace (list) – used internally for recursion

  • _output (list) – used internally for recursion

  • *args (list) – passed to func()

  • **kwargs (dict) – passed to func()

Examples:

data = dict(a=dict(x=[1,2,3], y=[4,5,6]), b=dict(foo='string', bar='other_string'))

# Search through an object
def check_type(obj, which):
    return isinstance(obj, which)

out = sc.iterobj(data, check_type, which=int)
print(out)


# Modify in place -- collapse mutliple short lines into one
def collapse(obj):
    string = str(obj)
    if len(string) < 10:
        return string
    else:
        return obj

sc.printjson(data)
sc.iterobj(data, collapse, inplace=True)
sc.printjson(data)
