如何将指定文本文件转换为{键: [数值列表]}格式的dictionary变量？

Got it! Let's turn your text file into the dictionary format you need. Here's a simple Python solution that does exactly what you're asking for:

def create_mincut_dict(file_path):
    mincut_dict = {}
    with open(file_path, 'r') as f:
        for line in f:
            # Clean up the line and convert all values to integers
            nodes = list(map(int, line.strip().split()))
            if nodes:  # Skip any empty lines in the file
                key_node = nodes[0]
                adjacent_nodes = nodes[1:]
                mincut_dict[key_node] = adjacent_nodes
    return mincut_dict

# Example usage:
# Replace 'kargerMinCut.txt' with the actual path to your file
final_dict = create_mincut_dict('kargerMinCut.txt')
# Print a sample to verify the format
print(f"Sample entry: 1 -> {final_dict[1]}")

How this works: #

• File Handling: We use a with statement to open the file safely—this ensures the file is automatically closed after processing, even if an error occurs.
• Line Processing: Each line is stripped of extra whitespace and split into individual elements, which we convert to integers (since your nodes are numeric).
• Dictionary Construction: The first number in each line becomes the dictionary key, and all subsequent numbers form the list of adjacent nodes for that key.
• Edge Case Handling: We skip empty lines to avoid errors, though your input file likely doesn't have any.

This will output a dictionary exactly in the format you specified: {1: [37, 79, ..., 196], ..., 200: [149,...,35]}.
