Python | Remove spaces from dictionary keys

In Python, dictionary is a collection which is unordered, changeable and indexed. Dictionaries are written with curly brackets, and they have keys and values. It is used to hash a particular key.

Let’s see how to remove spaces from dictionary keys in Python.

Method #1:
Using translate() function here we visit each key one by one and remove space with the none. Here translate function takes parameter 32, none where 32 is ASCII value of space ‘ ‘ and replaces it with none.

# Python program to remove space from keys
  
# creating a dictionary of type string
  
Product_list = {'P 01' : 'DBMS', 'P 02' : 'OS',
                'P 0 3 ': 'Soft Computing'}
  
# removing spaces from keys
# storing them in sam dictionary
Product_list = { x.translate({32:None}) : y 
                 for x, y in Product_list.items()}
  
# printing new dictionary
print (" New dictionary : ", Product_list)

                        filter_none









Output:


New dictionary :  {'P01': 'DBMS', 'P03': 'Soft Computing', 'P02': 'OS'}





 

Method #2: 

Using replace() function. In this method, we visit each key in dictionary one by one and replace all spaces in key with no space. This function takes as argument space and second non-space.
