For - Range

To loop through a set of code a specified number of times, we can use the range() function,
The range() function returns a sequence of numbers, starting from 0 by default, and increments by 1 (by default), and ends at a specified number.
Note that range(6) is not the values of 0 to 6, but the values 0 to 5.

for x in range(6): 
  print(x) 

The range() function defaults to 0 as a starting value, however it is possible to specify the starting value by adding a parameter: range(2, 6), which means values from 2 to 6 (but not including 6):

for x in range(2, 6): 
  print(x) 

for x in range(2, 30, 3): 
  print(x)
