find the index of a character in a string python

my_var = 'mummy'. #Find the position of 'm'

#Using find - find returns the index for the first instance from the left.
my_var.find('m')
# Output: 0

#Using rfind - rfind returns the index for the first instance from the right.
my_var.rfind('m')
# Output: 3
# With find() and rfind(), when substring is not found, it returns -1.

#NB: You can use index() and rindex(). In this case, when the substring is not
# found, it raises an exception.
