In Python programming, we use while loops to do a task a certain number of times repeatedly. The while loop checks a condition and executes the task as long as that condition is satisfied. The loop will stop its execution once the condition becomes not satisfied.

2 Looping with a for() statement. The formula Tn = n(n+1) evaluates the n-th. 2 triangular number, which counts the total number of dots in a triangular grid whose base has n dots. For example, there are 10 pins in a standard game of bowling because T4 = 10, and 15 balls in pool because T5 = 15.
Python Loop Exercises: For loop() and while loop() is used to iterate over each element or data depending upon the condition satisfied. While on the other side to control the flow of a program, we have control flow statements i.e. if, if-else statements in Python.
The keys method returns all keys in a dictionary, the values method returns all values in a dictionary and items method returns all key-value pairs in a dictionary. > a.keys() ['x', 'y', 'z'] > a.values() [1, 2, 3] > a.items() [('x', 1), ('y', 2), ('z', 3)] The for statement can be used to iterate over a dictionary.
