## Python | Convert a list of Tuples into Dictionary

Sometimes you might need to convert a tuple to dict object to make it more readable.

In this article, we will try to learn how to convert a list of tuples into a dictionary. Here we will find two methods of doing this.

**Examples:**

Input : [("akash", 10), ("gaurav", 12), ("anand", 14), ("suraj", 20), ("akhil", 25), ("ashish", 30)] Output : {'akash': [10], 'gaurav': [12], 'anand': [14], 'ashish': [30], 'akhil': [25], 'suraj': [20]} Input : [('A', 1), ('B', 2), ('C', 3)] Output : {'B': [2], 'A': [1], 'C': [3]} Input : [("Nakul",93), ("Shivansh",45), ("Samved",65), ("Yash",88), ("Vidit",70), ("Pradeep",52)] Output : {'Nakul': [93], 'Shivansh': [45], 'Samved': [65], 'Yash': [88], 'Vidit': [70], 'Pradeep': [52]} Input : [('Sachin', 10), ('MSD', 7), ('Kohli', 18), ('Rohit', 45)] Output : {'Sachin': 10, 'MSD': 7, 'Kohli': 18, 'Rohit': 45}

**Method 1 : Use of setdefault()**

Here we have used the dictionary method *setdefault()* to convert the first parameter to key and the second to the value of the dictionary. *setdefault(key, def_value)* function searches for a key and displays its value and creates a new key with def_value if the key is not present. Using the append function we just added the values to the dictionary.

**Example 1:**

`# Python code to convert into dictionary` ` ` `def` `Convert(tup, di):` ` ` `for` `a, b ` `in` `tup:` ` ` `di.setdefault(a, []).append(b)` ` ` `return` `di` ` ` `# Driver Code ` `tups ` `=` `[(` `"akash"` `, ` `10` `), (` `"gaurav"` `, ` `12` `), (` `"anand"` `, ` `14` `), ` ` ` `(` `"suraj"` `, ` `20` `), (` `"akhil"` `, ` `25` `), (` `"ashish"` `, ` `30` `)]` `dictionary ` `=` `{}` `print` `(Convert(tups, dictionary))` |

Output:

{'akash': [10], 'gaurav': [12], 'anand': [14], 'ashish': [30], 'akhil': [25], 'suraj': [20]}

**Example 2:**

`# Python code to convert into dictionary` `list_1` `=` `[(` `"Nakul"` `,` `93` `), (` `"Shivansh"` `,` `45` `), (` `"Samved"` `,` `65` `),` ` ` `(` `"Yash"` `,` `88` `), (` `"Vidit"` `,` `70` `), (` `"Pradeep"` `,` `52` `)]` `dict_1` `=` `dict` `()` ` ` `for` `student,score ` `in` `list_1:` ` ` `dict_1.setdefault(student, []).append(score)` `print` `(dict_1)` |

Output:

{'Nakul': [93], 'Shivansh': [45], 'Samved': [65], 'Yash': [88], 'Vidit': [70], 'Pradeep': [52]}

**Method 2 : Use of dict() method**

**Example 1:**

`# Python code to convert into dictionary` `def` `Convert(tup, di):` ` ` `di ` `=` `dict` `(tup)` ` ` `return` `di` ` ` `# Driver Code ` `tups ` `=` `[(` `"akash"` `, ` `10` `), (` `"gaurav"` `, ` `12` `), (` `"anand"` `, ` `14` `), ` ` ` `(` `"suraj"` `, ` `20` `), (` `"akhil"` `, ` `25` `), (` `"ashish"` `, ` `30` `)]` `dictionary ` `=` `{}` `print` `(Convert(tups, dictionary))` |

Output:

{'anand': 14, 'akash': 10, 'akhil': 25, 'suraj': 20, 'ashish': 30, 'gaurav': 12}

**Example 2:**

`# Python code to convert into dictionary` ` ` `print` `(` `dict` `([(` `'Sachin'` `, ` `10` `), (` `'MSD'` `, ` `7` `), (` `'Kohli'` `, ` `18` `), (` `'Rohit'` `, ` `45` `)]))` |

Output:

{'Sachin': 10, 'MSD': 7, 'Kohli': 18, 'Rohit': 45}

This is a simple method of conversion from a list or tuple to a dictionary. Here we pass a tuple into the dict() method which converts the tuple into the corresponding dictionary.
