The first “one line for loop” is applied on the range from “(1,6)”, and the print statement is used to print out all the elements in the specified range. In the second part, a variable named “list_1” is initialized, and the “One line for loop” iterates through the element...
Python provides various ways to writing for loop in one line. For loop in one line code makes the program more readable and concise. You can use for
We use the exec() function to dynamically execute a nested for loop, iterating through all combinations of elements from listOne and listTwo. Inside the loop, we print the sum of each pair (a, b) using the print(a + b) statement. Now, let’s have another example using the .join()...
a Simple One-LineforLoop in Python A simple one-lineforloop is the basicforloop that iterates through a sequence or an iterable object. You can use either an iterable object with theforloop or therange()function, and the iterable object can be a list, array, set, or dictionary. ...
