Looping Statements For Loop
The process of repetition of a set of instructions based on a criteria is
called a loop. There are two types of looping statements in Python, let us
study about them in detail.
Condition
Last item in True
The for Loop sequence?
The for loop is used to repeat a set of instructions for a fixed number of
times. It means when the number of iterations is known/definite before we False
start with the execution of a loop. It is therefore also known as a definite
loop. Indentation of statements is must to specify the block of statements Body for
to be repeated using for loop. Let us understand the flow of for loop Execute statements
with the help of a flowchart.
There are commonly two different ways of using for loop.
Exit for loop
Using Sequence
for <counter variable> in <sequence>:
Statements
Where,
• for is a reserved keyword.
• counter variable can be any identifier that keeps a count of the loop.
• sequence can be any value like integer, string, list etc.
• Statements always indented can be single or a block.
For examples:
Using range() Function
for <Var> in range(<Start>,<End+1>,<Step>):
<Statement>
Where,
• for is a reserved keyword.
• Start, end, step are parameters of range() function and will always be integers.
• Start=starting value of loop. end=ending value+1 of loop, Step=number of steps taken to reach the end
value.
