Python error when trying to access list by index - "List indices must be integers, not str"

will help you I have the following Python code : , Were you expecting player to be a dict rather than a list?
>>> player=[1,2,3]
>>> player["score"]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: list indices must be integers, not str
>>> player={'score':1, 'age': 2, "foo":3}
>>> player['score']
1

wish helps you First of all, you want an associative array, so use a dict instead of a list. Second, findall returns a list and you want the element.
id_key = {} # replaced [] with {}

for row in my_data:
    eventid = pattern_id.findall(row.decode('utf-8'))[0] # note added [0]
    eventkey = pattern_key.findall(row.decode('utf-8'))[0]
    id_key[eventid] = eventkey
id_key = {pattern_id.findall(row.decode('utf-8'))[0]: 
          pattern_key.findall(row.decode('utf-8'))[0] for row in my_data}
def id_and_key(line):
    return (pattern_id.findall(line)[0],  
            pattern_key.findall(line)[0])

id_key = dict(id_and_key(row.decode('utf-8')) for row in my_data)

Vowel indices: Python error "'in <string>' requires string as left operand, not int"

it fixes the issue You are trying to check if i, which is an integer, is included in the string vowel.
string = "And now for something completely different"
vowel = "aeiouAEIOU"

for i in range(0, len(string)):
    if string[i] in vowel:  
        print(string[i])

processing a list gives the error "list indices must be integers or slices, not tuple"

like below fixes the issue This code is meant to take a string as input, and then produce a 2d array of the frequency of letter appearing after each other. So for each iteration, it increases the value of the integer in the array (for example HI would be [h][i] =+ 1). , You made the nested list which you can access by below syntax:
x = letterArray[posY][posX]

Error "list indices must be integers or slices, not tuple" occurs when I try to use function parametrs as list

seems to work fine The problem is here gifts[-1, end_verse]. You are using a tuple as an index.
You should use just an integer value instead. Maybe you meant one of these options:
gifts[-1 + end_verse]
gifts[end_verse - 1]
gifts[-1]
gifts[end_verse]
