Creating dictionary from tuples A tuple will have values separated by “,” and enclosed by ‘ ()’ brackets. It will be helpful in use cases where we want to leverage the power of NumPy operations on existing data structures. 16, May 19. np.array() : Create Numpy Array from list, tuple or list of lists in Python Find max value & its index in Numpy Array | numpy.amax() Pandas : count rows in a dataframe | all … But there is a workaround. Use del keyword to remove any tuple, using index, from a list of tuples, as shown in this example program. Get the index of an item in Python List – 3 Easy Methods, Create an Empty List in Python – 2 Easy Ways, Check if a List is Empty – 3 Easy Methods, Creating a list of tuples — StackOverflow, Python list of tuples using zip() function, Customized grouping of elements while forming a list of tuples, Python list of tuples using map() function, Python list of tuples using list comprehension and tuple() method.

Tuples support operations similar to list type, only we cannot change the tuple elements. Below listed are some of the main advantages: We generally use tuples for heterogeneous (different) data types and lists for homogeneous (similar) data types. Tuple. dictionary using tuples Creating dictionary using key value pairs Tuples are used to store multiple items in a single variable. the elements of the tuple can be enclosed in a list and thus will follow the characteristics in a similar manner as of a Python list. link.
