Using range() Function
The range( ) function is an inbuilt function that is used to generate a sequence of values between the specified
range. The syntax to use the for loop with a range() function is:
for <Var> in range(<Start>,<End>,<Step>):
<Statements>
Where,
• for is a reserved keyword.
• Start, end, step are parameters of range() function and will always be integers.
• Start is a starting value of loop, End is an ending value (not inclusive) of loop, and Step is the number by which
counter variable will be incremented or decremented. By default step value is 1.
• If only one parameter is used the start becomes 0 and step becomes 1 as default.
• If Start > End then Step = is a negative integer.
• If Start < End then Step = is a positive integer.
• If Start >= End and Step value is not specified, the loop will not execute as this is an invalid condition.
For example:
[1]: for Count in range(1,5,1):
print("Welcome")
print("Iteration Finished")
Welcome
Welcome
Welcome
Welcome
Iteration Finished
