Given a delimiter (denoted as delim in code) separated string, order the splits in form of dictionary.
Examples :
Input : test_str = ‘gfg*is*best*for*geeks’, delim = “*”
Output : {0: ‘gfg’, 1: ‘is’, 2: ‘best’, 3: ‘for’, 4: ‘geeks’}
Input : test_str = ‘gfg*is*best’, delim = “*”
Output : {0: ‘gfg’, 1: ‘is’, 2: ‘best’}
Method 1 : Using split() + loop
This is a brute way in which this task can be performed. In this, the split sections are stored in a temporary list using split() and then the new dictionary is created from the temporary list.
Python3
# Using split() + loop # initializing string test_str = 'gfg_is_best_for_geeks' # printing original string print ( "The original string is : " + str (test_str)) # initializing delim delim = "_" # splitting using split() temp = test_str.split(delim) res = dict () # using loop to reform dictionary with splits for idx, ele in enumerate (temp): res[idx] = ele # printing result print ( "Dictionary after splits ordering : " + str (res)) |
Output:
The original string is : gfg_is_best_for_geeks
Dictionary after splits ordering : {0: ‘gfg’, 1: ‘is’, 2: ‘best’, 3: ‘for’, 4: ‘geeks’}
Method 2 : Using dictionary comprehension + split() + enumerate()
This is a shorthand method with the help of which this task can be performed. In this, we perform the task of dictionary reconstruction using one-liner dictionary(dictionary comprehension) and enumerate() is used to help in ordering.
Python3
# Using dictionary comprehesion + split() + enumerate() # initializing string test_str = 'gfg_is_best_for_geeks' # printing original string print ( "The original string is : " + str (test_str)) # initializing delim delim = "_" # using one liner to rearrange dictionary res = {idx: ele for idx, ele in enumerate (test_str.split(delim))} # printing result print ( "Dictionary after splits ordering : " + str (res)) |
Output:
The original string is : gfg_is_best_for_geeks
Dictionary after splits ordering : {0: ‘gfg’, 1: ‘is’, 2: ‘best’, 3: ‘for’, 4: ‘geeks’}
