Python - 将控制台 output 与 a.txt 进行比较

Question

I wrote a simple python application to print to console:我写了一个简单的 python 应用程序打印到控制台：

print("Hello!")
print("How's it going?")

I than created a text file called 'file.txt' with the following content:然后，我创建了一个名为“file.txt”的文本文件，其内容如下：

Hello!
How's it going?

Is there a way to check if code's output to the console is the same as content in 'file.txt'?有没有办法检查代码的 output 到控制台是否与'file.txt'中的内容相同？

(using windows) （使用窗户）

You can probably use the diff command.您可能可以使用diff命令。

diff a.txt <(python a.py)

Output: Output：

2c2
< How's it going?
\ No newline at end of file
---
> How's it going?

Note: This works in bash, ksh, and zsh.注意：这适用于 bash、ksh 和 zsh。
