Python programming language is extensively used due to its clean and easy-to-understand syntax. Executing iteration a certain number of times is a common programming task.

Using loops in Python, particularly the **for** loop, allows programmers to iterate a block of code several times. This tutorial will guide you on how to perform a loop a specific number of times in Python.

### Using the for Loop

The **for** loop in Python is commonly used for iterating over a sequence like lists, tuples, dictionaries, strings, or a range of numbers. Here is a simple way how you can loop a certain number of times:

1 2 |
for i in range(5): print(i) |

In the above example, **range(5)** generates a sequence of numbers from 0 up to 4, and for each number i in this range, the print function will be executed.

### Understanding the range() function

**Range()** is a built-in function of Python that is used to generate a sequence of numbers. If given one parameter, **range()** generates numbers from 0 to the specified number. If given two parameters, **range()** generates numbers from the first given number up to the second given number.

Finally, if given three parameters, **range()** generates numbers from the first number up to the second number with a step size defined by the third parameter.

1 2 |
for i in range(0, 10, 2): print(i) |

In this code, numbers from 0 to 8 with a step size of 2 are generated, printing even numbers from 0 to 8.

### Looping in Reverse Order

You may want to loop in reverse order which can be done using the **reversed()** function:

1 2 |
for i in reversed(range(5)): print(i) |

In this example, the **reversed()** function is used to reverse the sequence generated by **range(5)**.

## Full code

1 2 3 4 5 6 7 8 |
for i in range(5): print(i) for i in range(0, 10, 2): print(i) for i in reversed(range(5)): print(i) |

## Output

0 1 2 3 4 0 2 4 6 8 4 3 2 1 0

## Conclusion

Python offers the **for** loop to iterate a block of code a definite number of times. The flexibility of performing actions a specific number of times, with the possibility of controlling the start and stop points of the loop, as well as the step size, is a powerful feature. With the **range()** function and the **reversed()** function, you have numerous methods to control your loop operations.
