General UsageAs it returns a sequence of numbers, most of the developers use the range to write loops. This comes handy when you don’t have a list or tuple, but only a specific value to implement the loop. Variation OneHere we will implement a for loop with only one parameter — Here Variation TwoHere we will implement the for loop using start and stop as parameters. Variation ThreeNow, we will use all three parameters: As the step value is 2, instead of incrementing by 1, the loop increment by 2 on each iteration. One of the important things that we need to keep in mind is the step value should never be zero; else, It will throw a Iteration over list typesAlong with loops, Reverse RangeWe can give either positive or negative numbers for any of the parameters in the range. This feature offers the opportunity to implement reverse loops. We can do this by passing a higher index as a Create List, Set and Tuple using Rangerange() comes handy in many situations, rather than only using to write loops. For example, we create List, Set, and Tuple using range function instead of using loops to avoid boilerplate code. Have a look: To make it a bit more fun, we can pass negative values in step to create ascending order lists. Have a look: Indexing RangeLike the way we access values in the list using the index, we can do the same for range. The syntax is also similar to list index access. Float Arguments in RangeBy default, the TypeError: 'float' object cannot be interpreted as an integer But there is a workaround for this; we can write a custom Python function similar to the one below. It will allow you to specify a float value for the step argument. That is all for now, hope you learned something useful, thanks for reading. You can find me on Medium, Twitter, Quora and LinkedIn. What is range () in python give an example to explain it?Use a negative step value in a range() function to generate the sequence of numbers in reverse order. For example, range(5, -,1, -1) will produce numbers like 5, 4, 3, 2, and 1. I.e., you can reverse a loop by setting the step argument of a range() to -1. It will cause the for loop to iterate in reverse order.
What is range in list python?The range() function is used to get a sequence of numbers, starting from 0 by default, and increments by 1 by default, and ends at a specified number. Note: Sequence Types - list, tuple, range etc. An integer number specify starting position.
Does range () return a list?Python range() function
In Python 2, the range() returns a list which is not very efficient to handle large data.
What is range in for loop in python?The range() is a built-in function in Python. It's like the print() function in the sense that it's always available in the program. The range(n) generates a sequence of n integers starting at zero. It increases the value by one until it reaches n . So the range(n) generates a sequence of numbers: 0 , 1 , 2 , … n-1 .
