Python range() is a built-in function available with Python from Python(3. x), and it gives a sequence of numbers based on the start and stop index given. This by default uses 1 as the increment/step value. Python doesn't stop you from doing i = i + 1 inside the loop, but as soon as control goes back to the top of the loop i gets reset to whatever value is next in the sequence. For example, if(typeof ez_ad_units != 'undefined'){ez_ad_units.push([[580,400],'sparkbyexamples_com-box-4','ezslot_6',139,'0','0'])};__ez_fad_position('div-gpt-ad-sparkbyexamples_com-box-4-0'); If we want to increment for loop with a specified value we can pass step parameter along with start and stop of range() function.
