Python – Convert String to Nested Dictionaries
Sometimes, while working with dictionaries, we can have a problem in which we need to convert a String to nested dictionary, each separator occurrence meaning a new nesting. This is a particular problem but can occur in data domains and day-day programming. Let’s discuss certain way in which this task can be done.
Method : Using loop + recursion
This is way in which this task can be performed. In this, we recur for nesting of dictionary as we encounter a separator occurrence.
# Python3 code to demonstrate working of # Convert String to Nested Dictionaries# Using loop def helper_fnc(test_str, sep): if sep not in test_str: return test_str key, val = test_str.split(sep, 1) return {key: helper_fnc(val, sep)} # initializing stringtest_str = 'gfg_is_best_for_geeks' # printing original stringprint("The original string is : " + str(test_str)) # initializing separatorsep = '_' # Convert String to Nested Dictionaries# Using loopres = helper_fnc(test_str, sep) # printing result print("The nested dictionary is : " + str(res)) |
Output :
The original string is : gfg_is_best_for_geeks
The nested dictionary is : {'gfg': {'is': {'best': {'for': 'geeks'}}}}
