Python – Convert Dictionary to Concatenated String

Sometimes, while working with Dictionaries, we can have a task in which we need to perform the conversion of converting dictionary to string, which is concatenated key-value pair. This can have application in domains in which we require to reduce storage space or require strings as target data. Let’s discuss certain ways in which this task can be performed.

Method 1: Using an empty string + for loop

In this method, we will use a for loop to iterate through the dictionary object and keep on adding the key: value pairs to the empty string.

Output:

The original dictionary is : {'gfg': 1, 'is': 2, 'best': 3}
The dictionary after concatenation is :  gfg1is2best3

Method 2 : Using join() + items() 

The combination of above functions can be used to solve this problem. In this, we need to perform the task of concatenation using join() and extraction of dictionary items is done using items().
 

Output :

The original dictionary is : {'gfg': 1, 'best': 2, 'is': 3}
The dictionary after concatenation is : gfg1best2is3

 
Method 3 : Using reduce() + lambda 

The combination of above functions can be used to perform this task. In this, we perform the task of concatenation using combination of reduce() and lambda.
 

Output :

The original dictionary is : {'gfg': 1, 'best': 2, 'is': 3}
The dictionary after concatenation is : gfg1best2is3
