Write a note on different loop statements in python.

In Python, loop statements are used to execute a block of code repeatedly. There are two main types of loops in Python: "for" loops and "while" loops.

  1. For Loops:
    • The "for" loop in Python is used to iterate over a sequence (such as a list, tuple, string, or range) or any other iterable object.
    • Syntax:
      for item in iterable: # code block to be executed
    • Example:
      fruits = ["apple", "banana", "cherry"] for fruit in fruits: print(fruit)
  2. While Loops:
    • The "while" loop in Python repeatedly executes a target statement as long as a given condition is true.
    • Syntax:
      while condition: # code block to be executed
    • Example:
      i = 1 while i < 6: print(i) i += 1

These loops play a crucial role in automating repetitive tasks and iterating through data structures in Python. It's important to use loops efficiently to avoid infinite loops and optimize code execution.
