bookWriting your own functions (2/5)

All we have learned till now can be used inside the function. For example, you can easily put conditional statements inside the function body.

For example, we can define a function that will check if the number is odd or even.


              
12345678910

            
# define a function
def is_odd(n):
  if n % 2 == 0:
    return "even"
  else:
    return "odd"

# testing function
print('2 is', is_odd(2))
print('3 is', is_odd(3))
copy

Tarefa

Define a function is_positive checking if the number is positive (in that case return positive), negative (return negative), or equals zero (return zero).
