这个问题可能已经回答，但是经过大量时间搜索，网络和网络没有找到合适的答案。

我连续3个循环如下：

    w = my_text0.get(1.0, END).split()

    data = []
    # get & set the matching dict keys and values
    for i in w:
        if i in [*dictionary]:
            word = i.title()
            my_text.insert(END, word)
            my_text.insert(END, ", " + dictionary[i] + "\n")

            keys_len = len(word)
            print("keys_len", keys_len)
            data.append(keys_len)

    print("data", data)

    # print("keys_len", keys_len)
    # get text widget lines count
    txtwidg_lnescnt = int(my_text.index("end-1c").split(".")[0])

    for j in range(0, len(data)):
        k_l = data[j]
        print("k_l", k_l)
    print("k_l out", k_l)

    # get index start and end for tag_add method
    for k in range(1, txtwidg_lnescnt):
        lne_idx = k
        str_idx = f"{lne_idx}.0"
        end_idx = f"{lne_idx}.{k_l}"
        print("end_idx", end_idx)
        my_text.tag_add("start", str_idx, end_idx)
        my_text.tag_config(
            "start",
            background="red",
            foreground="black",
            font=bdfont,
        )

我需要在3rd loop中处理2nd loop的k_l值。 但是目前只处理2nd loop的最后一个值(9)。

这是我得到的输出：

keys_len 5
keys_len 6
keys_len 9
data [5, 6, 9]
k_l 5
k_l 6
k_l 9
k_l out 9
end_idx 1.9
end_idx 2.9
end_idx 3.9

我需要它：

keys_len 5
keys_len 6
keys_len 9
data [5, 6, 9]
k_l 5
k_l 6
k_l 9
k_l out 9
end_idx 1.5
end_idx 2.6
end_idx 3.9

我熟悉append to an empty list method来存储循环中的所有值。

但是我不能在这里重复，因为它已经在1st loop中完成了。

我还尝试使用return from a separate function method，但它像嵌套环一样输出，这不是我需要的：

def mykeyslengths():
    # get the user's entered words
    w = my_text0.get(1.0, END).split()

    data = []
    # get & set the matching dict keys and values
    for i in w:
        word = i

        keys_len = len(word)
        print("keys_lenzz", keys_len)
        data.append(keys_len)

    for j in range(0, len(data)):
        k_l = data[j]
        print("k_l", k_l)

    return k_l


def generate():
    # Clear The text
    my_text.delete(1.0, END)

    # get the user's entered words
    w = my_text0.get(1.0, END).split()

    # data = []
    # get & set the matching dict keys and values
    for i in w:
        if i in [*dictionary]:
            word = i.title()
            my_text.insert(END, word)
            my_text.insert(END, ", " + dictionary[i] + "\n")

    #         keys_len = len(word)
    #         print("keys_len", keys_len)
    #         data.append(keys_len)

    # print("data", data)

    # print("keys_len", keys_len)
    # get text widget lines count
    txtwidg_lnescnt = int(my_text.index("end-1c").split(".")[0])

    # for j in range(0, len(data)):
    #     k_l = data[j]
    #     print("k_l", k_l)
    # print("k_l out", k_l)

    # get index start and end for tag_add method
    for k in range(1, txtwidg_lnescnt):
        lne_idx = k
        str_idx = f"{lne_idx}.0"
        end_idx = f"{lne_idx}.{mykeyslengths()}"
        print("end_idx", end_idx)
        my_text.tag_add("start", str_idx, end_idx)
        my_text.tag_config(
            "start",
            background="red",
            foreground="black",
            font=bdfont,
        )

这样的输出：

keys_lenzz 5
keys_lenzz 6
keys_lenzz 9
k_l 5
k_l 6
k_l 9
end_idx 1.9
keys_lenzz 5
keys_lenzz 6
keys_lenzz 9
k_l 5
k_l 6
k_l 9
end_idx 2.9
keys_lenzz 5
keys_lenzz 6
keys_lenzz 9
k_l 5
k_l 6
k_l 9
end_idx 3.9

如果从示例中不清楚，我需要5, 6, 9到bold的长度，并修改由end_idx变量值以tkinter tag_add END INDEX属性确定的相应子线的长度的backgrounds和foregrounds。

我目前遇到的问题是，所有3个子字节（字典键）都是(9)相同的长度，而它们的长度都应相同（5、6、9）。
