Python Loops Tutorial

Range() in a for Loop 1/2

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

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!

Take a look at the following code:


              123
            
# Printing all numbers from 0 to 100
for i in range(101):
  print(i)

How does the code work?

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.

Look at the code below:


              123456789
            
# 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)

Tarea

Print numbers from -1 to -5, follow these steps:

Configure the for loop to display decreasing numbers from -1 to -5.
Print each number within the loop.
