(python 3) When using raw_input(), why does the function add "\n" to the input?

I searched the first page of Google but couldn't find an answer. This won't happen for int(raw_input()) weirdly enough. But if i type:

a = [raw_input() for i in range(int(raw_input()))]
print(a)

Example input: 5 1 2 3 4 5

The output will be: ['1\n', '2\n', '3\n', '4\n', '5\n']

I know this has something to do with the IDE (I run VSCode) but I have no clue how to fix it. Thank you.

Solution

  • In Python3.x, raw_input() and input() are integrated, raw_input() is removed, only the input() function is retained, which receives any input, defaults all input to string processing, and returns the string type.

    When use Python2.7:

    When use Python3.8:

    In addition, if you use extensions for debugging other than the python extension in VS Code, please try to disable it to avoid affecting the results.

    My environment:

    VS Code: 1.52.1 (user setup); OS: Windows_NT x64; VS Code extension: Python; Pylance;
