      Python Tutorial

      This Python tutorial has been written for the beginners to help them understand the basic to advanced concepts of Python Programming Language. After completing this tutorial, you will find yourself at a great level of expertise in Python, from where you can take yourself to the next levels to become a world class Software Engineer.

      Loops

      In general, statements are executed sequentially: The first statement in a function is executed first, followed by the second, and so on. There may be a situation when you need to execute a block of code several number of times.
      Programming languages provide various control structures that allow for more complicated execution paths.
      A loop statement allows us to execute a statement or group of statements multiple times. The following diagram illustrates a loop statement
      
      Python programming language provides following types of loops to handle looping requirements.
      Sr.No.
      Loop Type & Description
      1
      while loop
      Repeats a statement or group of statements while a given condition is TRUE. It tests the condition before executing the loop body.
      2
      for loop
      Executes a sequence of statements multiple times and abbreviates the code that manages the loop variable.
      3
      nested loops
      You can use one or more loop inside any another while, for or do..while loop.

      Loop Control Statements

      Loop control statements change execution from its normal sequence. When execution leaves a scope, all automatic objects that were created in that scope are destroyed.
      Python supports the following control statements. Click the following links to check their detail.
      Let us go through the loop control statements briefly
      Sr.No.
      Control Statement & Description
      1
      break statement
      Terminates the loop statement and transfers execution to the statement immediately following the loop.
      2
      continue statement
      Causes the loop to skip the remainder of its body and immediately retest its condition prior to reiterating.
      3
      pass statement
      The pass statement in Python is used when a statement is required syntactically but you do not want any command or code to execute.
