for Loop Increment by 2 in PythonPython Python Loop Created: March-04, 2021 | Updated: March-15, 2021 Show In everyiteration, a for loop increases the counter variable by a constant. A for loop with a counter variable sequence of 0, 2, 4, 6 wouldincrement by 2 per iteration. This article will introduce some methods to increment by 2 in the Python for loop. Increment by 2 in Python for Loop With the range() FunctionIn this function, we use the range() function. It has three parameters, start, stop, and step. This function iterates from the start value and increments by each given step but not including the stop value. The complete example code is given below. for x in range(0, 12, 2): print(x)If you are working in Python 2, you can also use the xrange() function. Output: 0 2 4 6 8 10Increment by 2 in Python for Loop Using the Slicing MethodThis method uses the slice operator : to increment the list values by 2 steps. In the code, the first digit represents the starting index (defaults to 0), the second represents the ending slice index (defaults to the end of the list), and the third represents the step. The complete example code is given below. my_list = [1,2,3,4,5,6,7,8,9,10] for x in my_list[1::2]: print (x)Output: 2 4 6 8 10Be aware that this method copies the original list to a new memory space. It will have a bad speed performance if the list is huge. Contribute DelftStack is a collective effort contributed by software geeks like you.
