range(start, end, step) code example

Example 1: python range from n to 0

range(N, -1, -1) is better

Example 2: range(n,n) python

# if numbers are same in the range function then,
# the range function outputs empty range
# this is because, there are no integers b/w n and n
for i in range(1,1):
  print("runs")

# prints nothing
