如何在python中处理非常大的文件(13 do )而不崩溃？

def process_large_file_line_by_line(file_path):
    with open(file_path, 'r') as file:
        for line in file:
            # 处理每一行数据
            process_line(line.strip())

def process_line(line):
    # 这里可以添加具体的处理逻辑
    print(line)

# 使用示例
process_large_file_line_by_line('path_to_large_file.txt')

def process_large_file_chunk_by_chunk(file_path, chunk_size=1024*1024):
    with open(file_path, 'rb') as file:
        while True:
            chunk = file.read(chunk_size)
            if not chunk:
                break
            # 处理每一块数据
            process_chunk(chunk)

def process_chunk(chunk):
    # 这里可以添加具体的处理逻辑
    print(chunk[:100])  # 示例：打印前100个字节

# 使用示例
process_large_file_chunk_by_chunk('path_to_large_file.bin')
