写入文件会将整数打印到我的 IDLE shell [英] Writing to a file prints integers to my IDLE shell

问题描述

写入文件会将整数打印到我的 IDLE shell.它们似乎在 15 到 40 之间，而且我的文件中打印的每一行都有一个.

Writing to a file prints integers to my IDLE shell. They seem to range from 15-40 and there's one for every line printed to my file.

这仅发生在我直接在 IDLE 中、在函数之外编写语句时.这会导致整数打印:

This only occurs if I write the statement directly in IDLE, outside of a function. This causes the integers to print:

>> file = open('filename', 'w')
>> for element in list:
       file.write('{}\n'.format(element))

虽然没有:

>> def print_to_file():
       file = open('filename', 'w')
       for element in list:
           file.write('{}\n'.format(element))
       file.close()
>> print_to_file()

我在 Windows 7 上使用 IDLE 3.4.0.我还没有机会在另一台机器或其他版本的 IDLE 上测试它.

I'm using IDLE 3.4.0 on Windows 7. I haven't had the opportunity to test it on another machine or another version of IDLE.

推荐答案

当您在交互式解释器中执行语句并且该语句是返回值的表达式时，将显示结果.write() 返回写入的字节数.

When you execute a statement in the interactive interpreter and that statement is an expression that returns a value, the result will be displayed. write() returns how many bytes were written.
