We will pass the list with * operator inside the into () parenthesis and this will unpack a list to tuple.

4. # initializing the list tuples = [ ('Key 1', 1), ('Key 2', 2), ('Key 3', 3), ('Key 4', 4), ('Key 5', 5)] # converting to dict result = dict(tuples) # printing the result print(result) (And Back) Watch this video on YouTube Print the converted tuple on the screen along with its data type to confirm the conversion. How to Convert List of Lists to List of Tuples in Python? This also works for a list of tuples with a varying number of elements. ); for a small input (particularly one that's already a listor tuple), the latter is slightly slower, but fine. Python provides different types of variables for programmers. 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. print(Int_tuple) output: [12,22,32,43,67] (12,22,32,43,67) Explanation: Here I take Integer Parameter for creating a list and convert that Integer data in a tuple and print that using the print () function.

The above code will result in the following output: ('a', 'b', 'c', 'd') output 1 2, Adding a new tuple to an existing tuple

asarray() function and then flatten the array using the flatten() method to . The list () is a built-in Python method that takes a tuple as an argument and returns the list. For example, if 4 is the dividend and 2 is the divisor then after dividing 4 with 2 the remainder will be 0. Converting set into tuple and tuple into set. >>> ''.join(codefather) 'codefather' How to convert a list into a tuple in Python without losing any values? In this, we perform the conversion using tuple (), and list comprehension is used to extend logic to all the containers. Output: 2. Example: value = ['Tim', 'John', 'Mark'] my_tuple = tuple (value) print (my_tuple) After writing the above code (Python convert list to a tuple), Ones you will print " my_tuple " then the output will appear as a " ('Tim', ' John', 'Mark') ". Once we have appended the value, we can turn it back to a tuple. To convert a tuple to list in Python, use the list () method. Note that the values in the tuple are not copiedonly a new reference to the same element is created: The graphic also shows how to convert a tuple back to a list by using the list () function (that's also a Python built-in function). In python there are infinite ways to do this, here are some instances Normal way >>> l= [1,2,"stackoverflow","python"] >>> l [1, 2, 'stackoverflow', 'python'] >>> tup = tuple (l) >>> type (tup) <type 'tuple'> >>> tup (1, 2, 'stackoverflow', 'python') smart way >>>tuple (item for item in l) (1, 2, 'stackoverflow', 'python') To create an empty tuple in Python, use a empty round brackets " () " with no items in it. You can use the Python built-in list () function to convert a tuple to a list. For example: 0.2, 5.89, 20.79, etc. list_names =['Meredith', 'Kristen', 'Wright', 'Franklin'] tuple_names = tuple( list_names) print( tuple_names) print(type( tuple_names)) Output ('Meredith', 'Kristen', 'Wright', 'Franklin') <class 'tuple'> Example 2 Following is an another example of this Return Value Method 1: One method is using the lambda function that converts the given tuple into a number. Three methods are given: Method 1: list to tuple. You can use tuple keyword to convert a list into a tuple. In the following code, we convert a list to a tuple using the tuple () built-in function. Given a list of tuples, write a Python program to convert it into list.
