s, representing the running total sum, is set to 0. The outer for-loop begins with looping variable, i, set to 0. Inner for-loop begins with looping variable, j, set to 0. s is incremented by x [i,j] = x [0,0] = 5. So s = 5. Inner for-loop sets j = 1. s is incremented by x [i,j] = x [0,1] = 6. So s ...

Jul 14, 2022 · Python For loop is used for sequential traversal i.e. it is used for iterating over an iterable like String, Tuple, List, Set or Dictionary. In Python, there is no C style for loop, i.e., for (i=0; i<n; i++). There is “for” loop which is similar to each loop in other languages. Let us learn how to use for in loop for sequential traversals

Python For Loops. A for loop is used for iterating over a sequence (that is either a list, a tuple, a dictionary, a set, or a string). This is less like the for keyword in other programming languages, and works more like an iterator method as found in other object-orientated programming languages. With the for loop we can execute a set of statements, once for each item in a list, tuple, set etc.
