以下是Python代码实现：

    print(f"time = {time}, prob = {prob}")
    
    # 找到字符串前面最接近字符串的时间
    idx = content.rfind(matches[i][0])
    if idx != -1:
        text = content[:idx]
        idx_start = text.rfind('[')
        idx_end = text.rfind(']')
        if idx_start != -1 and idx_end != -1:
            time_closest = text[idx_start+1:idx_end]
            print(f"closest time = {time_closest}")

输出结果：

closest time = 00:04:29
time = 00:11:14, prob = 0.937645

python如何查找TXT中指定字符后的字符串

可以使用Python中的字符串方法`find()`来查找指定字符后的字符串。具体步骤如下：

1. 打开TXT文件，读取文件内容。
2. 使用`find()`方法查找指定字符在文件内容中的位置。
3. 根据指定字符在文件内容中的位置，截取指定字符后的字符串。

下面是一个示例代码：

# 打开TXT文件，读取文件内容
with open('example.txt', 'r') as f:
    file_content = f.read()

# 指定字符
char = 'a'

# 使用find()方法查找指定字符在文件内容中的位置
char_index = file_content.find(char)

# 判断指定字符是否在文件内容中存在
if char_index != -1:
    # 根据指定字符在文件内容中的位置，截取指定字符后的字符串
    result = file_content[char_index + 1:]
    print(result)
else:
    print('指定字符不存在')

在上面的代码中，假设我们要查找文件中第一个出现的字母`a`后面的字符串。我们先打开文件`example.txt`，读取文件内容，并且指定字符为`a`。然后使用`find()`方法查找`a`在文件内容中的位置，如果`find()`方法返回的位置不是`-1`，则说明指定字符在文件内容中存在，我们就可以根据`a`在文件内容中的位置，使用切片截取`a`后面的字符串并输出。如果`find()`方法返回的位置是`-1`，则说明指定字符在文件内容中不存在，我们就输出一条相应的提示信息。
