1find 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.find an index of an item in a list python
#Example List
list = ['apples', 'bannas', 'grapes']
#Use Known Entites In The List To Find The Index Of An Unknown Object
Index_Number_For_Bannas = list.index('apples')
#Print The Object
