预置语句: while循环内的while循环。如何按组显示有序文件？

def display_ordered_file_by_group(file_path):
    groups = []
    current_group = None

    # 读取有序文件并存储在数据结构中
    with open(file_path, 'r') as file:
        for line in file:
            line = line.strip()
            if line.startswith('Group:'):
                current_group = line.split(':')[1].strip()
                groups.append({'group': current_group, 'lines': []})
            else:
                groups[-1]['lines'].append(line)

    # 按组显示有序文件
    for group in groups:
        print(f"Group: {group['group']}")
        sorted_lines = sorted(group['lines'])  # 对结果集进行排序
        for line in sorted_lines:
            print(line)

# 调用函数并传入有序文件的路径
display_ordered_file_by_group('path/to/ordered_file.txt')

Group: Group1
Line 1
Line 2
...

Group: Group2
Line 1
Line 2
...
