在列表中的项目中查找字符的索引 - Python3

Question

I'm trying to find the index of a character of an item in a list. For example:

list = ['hello','how','are','you']

How would I write some code that returns the "o" from 'hello', or the "r" from 'are', for example?

Answer 1

To reference a specific member, list[0][1] could be what you're looking for.

>>> list_of_words = ['hello','how','are','you']
>>> list_of_words[0][4]
'o'

If you're trying to find a specific character, you could iterate over your list and then iterate again over each member of the list to see if you've found your character

for word in words:
    for letter in word:
        # do comparison here

To find the number of the index, you can wrap your iteration in enumerate() to get a tuple of both the value and its index

for index, word in enumerate(words):
    ...

Also as a note for later, it's better not to name your list list , but something more descriptive, such as list_of_words , as it steps on the class (this means if you declared a list() in the same scope, it will try to reference your variable instead of the builtin)
