• understand the need for while loop
• Understand the syntax of the WHILE loop
• Apply the loop to get the desired result
• Predict the output for a group of statements.

Python while loop

• The while loop is also known as a pre-tested loop.
• In general, a while loop allows a part of the code to be executed as long as the given condition is true.
• It can be viewed as a repeating if statement. 
• The while loop is mostly used in the case where the number of iterations is not known in advance.

The syntax is given below. while expression:       statements   Here, the statements can be a single statement or the group of statements. The expression should be any valid python expression resulting into true or false.  The true is any non-zero value. Example 1 i=1;   while i<=10:       print(i);       i=i+1;   Output: 1 2 3 4 5 6 7 8 9 10
