The Python range() function returns the sequence of the given number between the given range. The most common use of it is to iterate sequence type (Python range() List, string, etc. ) with for and while loop using Python. Show
Syntax of range()
Example of Python range()Python3
Output: 0 2 4 6 8 What is the use of the range function in PythonIn simple terms, range() allows the user to generate a series of numbers within a given range. Depending on how many arguments the user is passing to the function, the user can decide where that series of numbers will begin and end as well as how big the difference will be between one number and the next.range() takes mainly three arguments.
Python range(stop)When the user call range() with one argument, the user will get a series of numbers that starts at 0 and includes every whole number up to but not including, the number that the user has provided as the stop. Example: Demonstration of Python range(stop)Python3
Output: 0 1 2 3 4 5 Python range(start, stop)When the user call range() with two arguments, the user gets to decide not only where the series of numbers stops but also where it starts, so the user don’t have to start at 0 all the time. Users can use range() to generate a series of numbers from X to Y using range(X, Y). Example: Demonstration of Python range(start, stop)Python3
Output: 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 Python range(start, stop, step)When the user call range() with three arguments, the user can choose not only where the series of numbers will start and stop but also how big the difference will be between one number and the next. If the user doesn’t provide a step, then range() will automatically behave as if the step is 1. In this example, we are printing an even number between 0 to 10 so we choose our starting point from 0(start = 0) and stop the series at 10(stop = 10). For printing an even number the difference between one number and the next must be 2 (step = 2) after providing a step we get the following output ( 0, 2, 4, 8). Example: Demonstration of Python range(start, stop, step)Python3
Output: 0 2 4 6 8 Python range() with ExamplesExample 1: Incrementing the range using a positive stepIf a user wants to increment, then the user needs steps to be a positive number. Python3
Output : 0 4 8 12 16 20 24 28 Example 2: Python range() using negative stepIf a user wants to decrement, then the user needs steps to be a negative number. Python3
Output : 25 23 21 19 17 15 13 11 9 7 5 3 1 Example 3: Python range() with floatPython range() function doesn’t support the float numbers. i.e. user cannot use floating-point or non-integer numbers in any of its argument. Users can use only integer numbers. Python3
Output : for i in range(3.3): TypeError: 'float' object cannot be interpreted as an integer Example 4: Concatenation of two range() functions using itertoolsThe result from two range() functions can be concatenated by using the chain() method of itertools module. The chain() method is used to print all the values in iterable targets one after another mentioned in its arguments. Python3
Output: Concatenating the result 0 1 2 3 4 10 12 14 16 18 Example 5: Accessing range() with an index valueA sequence of numbers is returned by the range() function as its object that can be accessed by its index value. Both positive and negative indexing is supported by its object. Python3
Output: First element: 0 Last element: 9 Fifth element: 4 Some Important points to remember about the Python range() function:
How do you use the range of a string in Python?The most common use of it is to iterate sequence type (Python range() List, string, etc. ) with for and while loop using Python.. range(stop) takes one argument.. range(start, stop) takes two arguments.. range(start, stop, step) takes three arguments.. How do you set a range in Python?Steps to use range() function. Pass start and stop values to range() For example, range(0, 6) . Here, start=0 and stop = 6 . ... . Pass the step value to range() The step Specify the increment. ... . Use for loop to access each number. Use for loop to iterate and access a sequence of numbers returned by a range() .. What is range () function in Python?Python range() Function
The range() function returns a sequence of numbers, starting from 0 by default, and increments by 1 (by default), and stops before a specified number.
How do you print the range of a string in Python?“python get range of characters in string” Code Answer. my_string = "Hey, This is a sample text". print(my_string[2:]) #prints y, This is a sample text.. print(my_string[2:7]) #prints y, Th excluding the last index.. print(my_string[2::2]) #prints y hsi apetx.. |
