Python – Remove double quotes from dictionary keys

Last Updated : 14 Oct, 2020

Given dictionary with string keys, remove double quotes from it.

Input : test_dict = {‘”Geeks”‘ : 3, ‘”g”eeks’ : 9}
Output : {‘Geeks’: 3, ‘geeks’: 9}
Explanation : Double qoutes removed from keys.
Input : test_dict = {‘”Geeks”‘ : 3}
Output : {‘Geeks’: 3}
Explanation : Double qoutes removed from keys.

Method #1 : Using dictionary comprehension + replace()

The combination of above functionalities can be used to solve this problem. In this, we perform removal of double quotes using replace() with empty string. The dictionary comprehension is used for remaking dictionary.

Python3

# Python3 code to demonstrate working of 
# Remove double quotes from dictionary keys
# Using dictionary comprehension + replace()
  
# initializing dictionary
test_dict = {'"Geeks"' : 3, '"is" for' : 5, '"g"eeks' : 9}
  
# printing original dictionary
print("The original dictionary is : " + str(test_dict))
  
# dictionary comprehension to make double quotes free
# dictionary
res = {key.replace('"', ''):val for key, val in test_dict.items()}
      
# printing result 
print("The dictionary after removal of double quotes : " + str(res)) 

Output

The original dictionary is : {'"Geeks"': 3, '"is" for': 5, '"g"eeks': 9}
The dictionary after removal of double quotes : {'Geeks': 3, 'is for': 5, 'geeks': 9}

Method #2 : Using re.sub() + dictionary comprehension

The combination of above functions is also an alternative to solve this task. In this, we employ regex to solve the problem.

Python3

# Python3 code to demonstrate working of 
# Remove double quotes from dictionary keys
# Using re.sub() + dictionary comprehension
import re
  
# initializing dictionary
test_dict = {'"Geeks"' : 3, '"is" for' : 5, '"g"eeks' : 9}
  
# printing original dictionary
print("The original dictionary is : " + str(test_dict))
  
# regex making replacement of double quotes with empty string 
res = {re.sub(r'"', '', key): val for key, val in test_dict.items()}
      
# printing result 
print("The dictionary after removal of double quotes : " + str(res)) 

Output

The original dictionary is : {'"Geeks"': 3, '"is" for': 5, '"g"eeks': 9}
The dictionary after removal of double quotes : {'Geeks': 3, 'is for': 5, 'geeks': 9}
