Aloopis a sequence of instructions that is continually repeated until a certain condition is reached. For instance, we have a collection of items and we create a loop to go through all elements of the collection. Loops in Python can be created withfororwhilestatements. Python for statement Py...

This loop will print a sequence of numbers from 0 to 4, iterating a set number of times. Notice how the range function will automatically increment the i counter. The loop iterates through all values of i from 0 to 4, which correspond to a range of 5. In python programming, the coun...
etc. As long as the length of the sequence is not reached, it will iterate over that sequence. The for loop contains initialization, the test expression, and the increment/decrement expression in the C language. Whereas in the case of python, we only have to mention the value and the seq...
However, the for loop in Python works fundamentally differently than for loops in other languages. Most programming languages use a loop variable, which is incremented or decremented with each successful iteration of the loop. Operation Meaning Typical syntax Python syntax Increment Increase the value...
