How does range() differ from enumerate()?

The range() and enumerate() functions serve different purposes in Python:

range()

• Purpose: Generates a sequence of numbers.
• Usage: Commonly used in loops to iterate over a sequence of numbers.
• Example:

  for i in range(5):
      print(i)

  This will output numbers from 0 to 4.

enumerate()

• Purpose: Adds a counter to an iterable (like a list or a string) and returns it as an enumerate object.
• Usage: Useful when you need both the index and the value of items in a loop.
• Example:

  fruits = ["apple", "banana", "cherry"]
  for index, fruit in enumerate(fruits):
      print(index, fruit)

  This will output:

  0 apple
  1 banana
  2 cherry

Summary

• Use range() when you need a sequence of numbers.
• Use enumerate() when you need to iterate over an iterable and also keep track of the index.
