Python program to split the string and convert it to dictionary

Last Updated : 01 Oct, 2020

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’}
