What is the purpose of the itertools.count() function?
A. To count the number of elements in an iterator
B. To generate an increasing sequence of numbers
C. To calculate the average of elements
D. To calculate the sum of elements
Answer: Option B
Solution (By Examveda Team)
The correct answer is Option B: To generate an increasing sequence of numbers.The purpose of the itertools.count() function is to generate an infinite sequence of numbers starting from a specified start value (default is 0) and incrementing by a specified step value (default is 1). This function returns an iterator that produces an unending sequence of numbers, allowing you to create iterators for counting purposes or for generating sequences of increasing numbers. It is commonly used in scenarios where you need to generate an infinite sequence of numbers or to create an index for iterating over another iterable.
