Why does my code give the TypeError: TypeError: 'int' object has no attribute '__getitem__'?

Question

我正在 Python 上编写一个脚本，你给一个字符串，它会找到字符串中字母的计数，将其输入到一个列表中，然后将该列表相加。我的脚本运行程序不断出现此错误：

Traceback (most recent call last):
File "Untitled.py", line 9, in <module>
countersplit = len(tosplit[counter])
TypeError: 'int' object has no attribute '__getitem__'

我的代码如下：

userin = raw_input("Enter sentence: ")
split = userin.split()
tosplit = len(split)
print(tosplit)
counter = 0
countersplit = 0
while counter < tosplit:
    countersplit = len(tosplit[counter])
    wordcount = [countersplit]
    print(wordcount)
    print(countersplit)
    counter = counter + 1

你能解决这个问题吗？

Answer 1

也许这就是您要实现的目标。

userin = raw_input("Enter sentence: ")
split = userin.split()
word_counts = list()
total_letters = 0
for i in split:
    word_count = len(split)
    print(word_count)
    word_counts.append(word_count)
    total_letters += word_count
print(total_letters)

Answer 2

您收到此错误是因为 "tosplit[counter]"。根据您的定义 "tosplit" 是一个等于 "split" 长度的整数。因此，您不能像在 tosplit[counter] 中那样拥有和索引。为了解决您的问题，这是您需要的吗？

from collections import defaultdict
import string
letters = list(string.ascii_lowercase)
string  = input('Enter a String : ')

string = string.lower()

d = defaultdict(int)

for i in string:

    if i in letters:
        d[i]+=1
