The range() function is used to generate a list of numbers. Only integer numbers are allowed, and hence, parameters can be both negative and positive. The following parameters are
acceptable:
range(stop)
Where ‘stop’ is the no. of integers to generate, starting from 0. Example: range(5) == [0,1,2,3,4]
range([start], stop[, step])
Start: gives the starting no. of the sequence
Stop: specifies the upper limit for the sequence
Step: is the incrementing factor in the sequence
