Note: As clear from the above example, the variable in for in loop holds the elements of the iterable object one by one, whereas the variable in for in range loop holds the indexes of the elements. Print(array,end=" ") Output T u t o r i a l s If indexes are needed, use for in range loop. This loop iterates over all the elements of the iterable object one by one without taking into account their index. It cannot be used to iterate over some specific integer range. This loop is used to iterate over a iterable object such as string or array. Let’s understand with the help of the below example. The number of steps forward will be specified by this parameter. If the parameter is positive, the loop will iterate in forward order. The number of steps (jumps) backwards will be specified by this parameter. If the third parameter is negative, it specifies that the loop will iterate in reverse order. The third parameter, in actual, specifies the steps the variable should jump. The third parameter in the for loop can be modified to use for loop in different ways. Print(i,end=" ") Output 5 4 3 2 1 Specify third parameter in the for loop The loop starts from starting value and iterates in decreasing order to the end value(not inclusive). The for in range loop can take a third parameter -1, which specifies that the for loop will iterate in reverse order. The starting value is inclusive but the end value is not inclusive. This means that if the starting and end values are 1 and 5 respectively, then the loop will iterate for 1,2,3,4. Note: The for loop in Python iterates one less than the end value. ![]() 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. ![]() Syntax for variable in range( starting value, end value) In simple terms, range () allows the user to generate a series of numbers within a given range. When used in a for loop, range() provides a simple way. If only one integer parameter is specified, then the specified integer is taken as the end of the range and the starting is 0 by default. The range() function generates a sequence of numbers from start up to stop, and increments by step. It takes the two integer values which specify the range within which the variable must iterate. ![]() Most of the programming questions we encounter make use of the for loop in its solution. The for loop is the most frequently used looping statement. The elements might be of an array, string or any other iterative object in Python. The for loop in Python is used to iterate over a number of elements or some specific integer range.
