在python中快速迭代读取文件

def file_iterator(file_path):
    with open(file_path, 'r') as file:
        for line in file:
            yield line.strip()

# 使用迭代器逐行读取文件
for line in file_iterator('file.txt'):
    print(line)

def file_generator(file_path, chunk_size=4096):
    with open(file_path, 'r') as file:
        while True:
            chunk = file.read(chunk_size)
            if not chunk:
                break
            yield chunk

# 使用生成器按块读取文件
for chunk in file_generator('file.txt'):
    print(chunk)
