    dosomething()
#The i is an iteration variable that you can replace by anytthing. You do not need to define it.

Example 2: Range python iterate by 2

for i in range(0,10,2):
  print(i)

Example 3: 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
