Range

Python range() function¶

The range() function gives you a bunch of numbers. An ordered bunch of numbers. Simple series like 1, 2, 3, 4.

# A typical use of range. This gives you 0, 1, 2
range(3)

Now, the output type of the range() function is a range object. Don't get confused, the output of range() is always a bunch of numbers.

The range() function and for loops are like best buddies in Python. One creates a sequence of numbers, and the other loops through it.

 print(*(i for i in range(3))) 
 0 
 1 
 2 
 range(3) -> 0, 1, 2 

 range(10)[-1] 
 9 

 print(*(fruits[i] for i in range(len(fruits)))) 
 apple 
 banana 
 cherry 
 date 
 * unpacks the items 

 print(*(i for i in range(10, 0, -2))) 





 Backwards using minus number 

  list( range( 5))  
 [0,1,2,3,4] 

print(*(fruits[i] for i in range(len(fruits))))
