python, list, index function

list.index(element)

#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
print(list[Index_Number_For_Bannas])

my_string = "Hello World!"

my_string.index("l") # outputs 2
# this method only outputs the index of the first "l" value in the string/list

# Make the list
list = ['bananas', 'apples', 'watermellon']
# Print the word apples from the list
print(list[1])

# vowels list
vowels = ['a', 'e', 'i', 'o', 'i', 'u']

# index of 'e' in vowels
index = vowels.index('e')
print('The index of e:', index)

# element 'i' is searched
# index of the first 'i' is returned
index = vowels.index('i')

print('The index of i:', index)
