range¶

range(X) generates sequence of integer object

range (lower_bound, upper_bound, step_size)  
# lower bound is optional, default = 0
# upper bound is not included in result
# step is optional, default = 1

Use list() to convert in order to view actual sequence of data

In [68]:

r = range(10)     # default lower bound =0, step =1
print (type (r))
print (r)
print (list(r))

<class 'range'>
range(0, 10)
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]

More Examples

In [69]:

print (list(range(2,8)))    # step not specified, default 1
print ('Odds Number : ' , list(range(1,10,2))) # generate odds number

[2, 3, 4, 5, 6, 7]
Odds Number :  [1, 3, 5, 7, 9]
