Ways to convert string to dictionary Last Updated : 21 Jan, 2025 Summarize Comments Improve Suggest changes Share Like Article Like Report To convert a String into a dictionary, the stored string must be in such a way that a key: value pair can be generated from it. For example, a string like "{'a': 1, 'b': 2, 'c': 3}" or "a:1, b:10" can be converted into a dictionary This article explores various methods to perform this conversion efficiently.Using eval() eval() function allows us to evaluate a string as Python code. If the string is formatted as a valid Python dictionary, we can directly convert it into a dictionary using this function. Python s = "{'a': 1, 'b': 2, 'c': 3}" res = eval(s) print(res) Output{'a': 1, 'b': 2, 'c': 3} Explanation:eval() function parses the string 's' as Python code.Since the string is formatted as a dictionary, it is directly converted into a dictionary object.Let’s explore some more ways and see how we can convert string to dictionary.Table of ContentUsing the json moduleUsing the ast.literal_eval functionUsing string manipulationUsing json moduleIf the string is in JSON format, we can use the json module to parse it and convert it into a dictionary. Python import json s = '{"a": 1, "b": 2, "c": 3}' res = json.loads(s) print(res) Output{'a': 1, 'b': 2, 'c': 3} Explanation:The json.loads function parses the string s as a JSON object.It converts the JSON object into a Python dictionary.This method is safe and ideal for strings in JSON format.Using ast.literal_eval functionast module provides the literal_eval function, which is similar to eval but safer. It only evaluates strings containing literals, such as dictionaries, lists, and numbers. Python import ast s = "{'a': 1, 'b': 2, 'c': 3}" res = ast.literal_eval(s) print(res) Output{'a': 1, 'b': 2, 'c': 3} Explanation:ast.literal_eval() function parses the string 's' as a literal.It converts the string into a dictionary if it is formatted as one.Using string manipulationIf the string is not formatted as a dictionary, we can manually process it using string operations to convert it into a dictionary. Python s = "a:1, b:2, c:3" res = {x.split(":")[0]: int(x.split(":")[1]) for x in s.split(", ")} print(res) Output{'a': 1, 'b': 2, 'c': 3} Explanation:We split the string into key-value pairs using the comma and space as a separator.Each pair is further split using the colon to extract the key and value.The result is built as a dictionary using a dictionary comprehension.

In Python, a dictionary stores information using key-value pairs. But if we want to save this data to a file, share it with others, or send it over the internet then we need to convert it into a format that computers can easily understand. JSON (JavaScript Object Notation) is a simple format used fo 6 min read Convert Unicode String to Dictionary in Python Python's versatility shines in its ability to handle diverse data types, with Unicode strings playing a crucial role in managing text data spanning multiple languages and scripts. When faced with a Unicode string and the need to organize it for effective data manipulation, the common task is convert 2 min read Python - Converting list string to dictionary Converting a list string to a dictionary in Python involves mapping elements from the list to key-value pairs. A common approach is pairing consecutive elements, where one element becomes the key and the next becomes the value. This results in a dictionary where each pair is represented as a key-val 3 min read Ways to create a dictionary of Lists - Python A dictionary of lists is a type of dictionary where each value is a list. These dictionaries are commonly used when we need to associate multiple values with a single key.Initialize a Dictionary of ListsThis method involves manually defining a dictionary where each key is explicitly assigned a list 3 min read Python - Convert Dictionary Object into String In Python, there are situations where we need to convert a dictionary into a string format. For example, given the dictionary {'a' : 1, 'b' : 2} the objective is to convert it into a string like "{'a' : 1, 'b' : 2}". Let's discuss different methods to achieve this:Using strThe simplest way to conver 2 min read Convert a list of Tuples into Dictionary - Python Converting a list of tuples into a dictionary involves transforming each tuple, where the first element serves as the key and the second as the corresponding value. For example, given a list of tuples a = [("a", 1), ("b", 2), ("c", 3)], we need to convert it into a dictionary. Since each key-value p 3 min read Like
