python with open

Python中的with open语句是一种方便的文件操作方式，它可以自动帮助我们调用close()方法，无需手动关闭文件。这种语句的常见用法是将文件对象赋值给一个变量，并在冒号后面的代码块中对文件进行操作。例如，使用with open语句读取文件内容可以这样写：

with open('/path/to/file', 'r') as f:
    print(f.read())

这样做的好处是代码更简洁且不需要手动调用f.close()方法来关闭文件。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
