Imagine that we wish to print numbers from 1 to 100. Naturally, we could do this manually:

```python
print(1, 2, 3, 4, 5, 6, ... 100)
```

But that would be incredibly time-consuming!

If we had to print numbers from 1 to 1,000,000, we'd be counting manually for the rest of our lives!

To tackle this challenge, we'll employ the `for` loop in conjunction with the `range()` function!

# Printing all numbers from 0 to 100
for i in range(101):
  print(i)

The ``range()`` function provides a sequence of numbers that starts at 0 (by default) when the initial limit is unspecified. It increments by 1 (by default) until it reaches a final limit (the final limit itself is not included).

The format of the ``range()`` function is: ``range(start, end, step)``.

If our intention is to operate with decreasing numbers, we can achieve this by inputting a negative **step** argument into the ``range()`` function.

# Increasing
# Printing numbers from 0 to 10
for i in range(0, 11, 1):
  print(i)

# Decreasing
# Printing numbers from 10 to 0
for i in range(10, -1, -1):
  print(i)

Python provides three ways for executing the loops. While all the ways provide similar basic functionality, they differ in their syntax and condition checking time. Today we start learning these loops. Welcome to Python Loops Tutorial!

We start learning Python loops with the for loop. A for loop is used for iterating over a sequence. Let's go!

With the while loop, we can execute a set of statements as long as a condition is true. We are going to work with this loop and handle different problems!

A nested loop is a loop inside a loop. Sound difficult? Don't worry! We will handle this loop!
