Question

Compare lists and tuples. Which one is not right?

a)"Lists can be edited, but Tuples cannot be edited."
b)Lists are usually faster than tuples
c)Lists consume more memory than tuples
d)Lists are less reliable than Tuples

Answer 1

The incorrect statement when comparing lists and tuples is 'Lists are usually faster than tuples', as the immutability of tuples can enable certain speed optimizations, making tuples generally faster than lists for some operations.

Step-by-step explanation:

When comparing lists and tuples in Python, statement b) 'Lists are usually faster than tuples' is not right. In reality, tuples are generally faster than lists because of their immutability. This means that once a tuple is created, it cannot be modified, which allows Python to make optimizations that make tuples slightly faster for certain operations than lists.

As for the other options:

• a) 'Lists can be edited, but Tuples cannot be edited.' - This is true; lists are mutable, whereas tuples are immutable.
• c) 'Lists consume more memory than tuples.' - This is also true; the mutable nature of lists means they need to have extra space to allow for changes, leading to higher memory usage.
• d) 'Lists are less reliable than Tuples.' - This statement is subjective and depends on the context. In terms of data integrity, immutability can be considered more 'reliable' in that a tuple won't accidentally be altered.
