Why tuple is faster than list

So Python just needs to allocate enough memory to store the initial elements. To get the size of an object, you use the getsizeof function from the sys module. When you copy a list, Python creates a new list. The following example illustrates copying a list to another:. However, when copying a tuple, Python just reuses an existing tuple.

TypeError : 'tuple' object does not support item assignment. The size of the list is 80 bytes. The size of the tuple is 64 bytes. What are the differences between Lists and Tuples? Which one is faster to access list or a tuple and why?

What is List Comprehension in Python? What is the use of negative indexing in the list? What are generators in Python? What is context manager in Python? Tuple is slightly faster to access than list. Following program compares speed benchmark for list and tuple. The main image from this piece is a Photo by Julia Joppien on Unsplash. What is a List List in python is simply a collection which is ordered and changeable.

Why should lists be used for homogeneous data and tuple for heterogeneous data? Main reason why list is preferred for homogeneous data is because it is mutable If you have list of several things of same kind, it make sense to add another one to the list or take one from it. You are still left with a list of same things But why is tuple different?

Since tuple is immutable, it can be used as key for dictionary Why is tuple faster than list? Whats the problem with list, anyway? What does tuple do? Thus, making a tuple of five elements will cost only five elements worth of memory.
