what does elif do in python code example

Example 1: elif python

The elif statement allows you to check multiple expressions for TRUE 
and execute a block of code as soon as one of the conditions evaluates
to TRUE. Similar to the else, the elif statement is optional. However,
unlike else, for which there can be at most one statement, there can 
be an arbitrary number of elif statements following an if.

if expression1:
   statement(s)
elif expression2:
   statement(s)
elif expression3:
   statement(s)
else:
   statement(s)

Example 2: python if elif

num = 20
if num > 30:
  print("big")
elif num == 30:
  print("same")
else:
  print("small")
#output: small

Example 3: else if python

if (condion):
   result
    
elif (condition):
   results
    
else:
   result

Example 4: python else elif

>>> a = 5
>>> if a > 5:
...     a = a + 1
... elif a == 5:
...     a = a + 1000
... else:
...     a = a - 1
... 
>>> a
1005
