Python 如何将文件拆分为字符

我正在制作一个python函数来查找文件中最常见的字母。但是，我无法将文件拆分为字符

以下是我目前的代码：

def common_letter_file(file):
    try:
        handle = open(file)
    except:
        print('Enter a valid file. Make sure the file is in the same directory as your python program')
        quit()
    for line in handle:
        words = line.split()
        for word in words:
            letter_list = [char for char in word]
        print(letter_list)
    counts = dict()
    for letter in letter_list:
        counts[letter] = counts.get(letter, 0) + 1
    biggest_count = None
    common_letter = None
    for letter,count in counts.items():
        if biggest_count is None or count > biggest_count:
            biggest_count = count
            common_letter = letter
    print('The most common letter was',common_letter,'and its count was',biggest_count)

尝试和排除以及找到频率最高的角色是有效的。但是，将文件扩展到列表中是不起作用的

请帮助，谢谢

您可以将字符串拆分为单独的字符，如下所示：

>>> my_str = "foo"
>>> list(my_str)
['f', 'o', 'o']

编辑： 就KAVAY而言，这就足够了：

list(handle.read().replace("\n", ""))

---

并且会按文件顺序返回列表中的每个字符。

我想将文件拆分为字符，而不是字符string@KAVAYSHARMA_ITSMEKAV在您的情况下，您可以使用

列表（handle.read（）.replace（“\n”，”）

非常感谢您的帮助answer@KAVAYSHARMA_ITSMEKAV如果答案回答了你的问题，就接受它！是的，它显示在3分钟内接受答案

line = "Ihavebeenworkingfor9hours"
line.split()

for i in line.split(): # need not to convert it to explicitly
    print(i)           # the better to check the lines
    for j in i:
        print(j)
