get index of character in python list

What would be the best way to find the index of a specified character in a list containin开发者_JS百科g multiple characters?

---

>>> ['a', 'b'].index('b')
1

If the list is already sorted, you can of course do better than linear search.

---

Probably the index method?

a = ["a", "b", "c", "d", "e"]
print a.index("c")

---

As suggested by others, you can use index. Other than that you can use enumerate to get both the index as well as the character

for position,char in enumerate(['a','b','c','d']):
    if char=='b':
        print position

def lookallindicesof(char, list):
    indexlist = []
    for item in enumerate(list):
        if char in item:
            indexlist.append(item[0])
    return indexlist

indexlist = lookllindicesof('o',mylist1)
print(indexlist)
