摘要：代碼于是我就利用的代碼片段功能編寫了一個用于處理這些輸入輸出的代碼框架，并加入了測試功能寫函數前先寫測試時正確的事情。

最近在實習，任務并不是很重，就利用閑暇時間使用Python3在PAT網站上刷題，并致力于使用Python3的特性和函數式編程的理念，其中大部分題目都有著類似的輸入輸出格式，例如一行讀入若干個數字，字符串，每行輸出多少個字符串等等，所以產生了很多重復的代碼。

于是我就利用VS Code的代碼片段功能編寫了一個用于處理這些輸入輸出的代碼框架，并加入了測試功能（寫函數前先寫測試時正確的事情）。代碼如下

"""Simple Console Program With Data Input And Output."""
import sys
import io


def read_int():
    """Read a seris of numbers."""
    return list(map(int, sys.stdin.readline().split()))


def test_read_int():
    """Test the read_int function"""
    test_file = io.StringIO("1 2 3
")
    sys.stdin = test_file
    assert read_int() == [1, 2, 3], "read_int error"


def read_float():
    """Read a seris of float numbers."""
    return list(map(float, sys.stdin.readline().split()))


def test_read_float():
    """Test the read_float function"""
    test_file = io.StringIO("1 2 3
")
    sys.stdin = test_file
    assert read_float() == [1.0, 2.0, 3.0], "read_float error"


def read_word():
    """Read a seris of string."""
    return list(map(str, sys.stdin.readline().split()))


def test_read_word():
    """Test the read_word function"""
    test_file = io.StringIO("1 2 3
")
    sys.stdin = test_file
    assert read_word() == ["1", "2", "3"], "read_word error"


def combine_with(seq, sep=" ", num=None):
    """Combine list enum with a character and return the string object"""
    res = sep.join(list(map(str, seq)))
    if num is not None:
        res = str(seq[0])
        for element in range(1, len(seq)):
            res += sep + 
                str(seq[element]) if element % num != 0 else "
" + 
                str(seq[element])
    return res


def test_combile_with():
    """Test the combile_with function."""
    assert combine_with([1, 2, 3, 4, 5], "*", 2) == """1*2
3*4
5""", "combine_with error."


def main():
    """The main function."""
    pass


if __name__ == "__main__":
    sys.exit(int(main() or 0))

添加到VS Code的默認代碼片段的操作大致如下：

文件->首選項->用戶代碼片段，選擇Python

編輯"python.json"文件如以下內容

{
/*
     // Place your snippets for Python here. Each snippet is defined under a snippet name and has a prefix, body and 
     // description. The prefix is what is used to trigger the snippet and the body will be expanded and inserted. Possible variables are:
     // $1, $2 for tab stops, ${id} and ${id:label} and ${1:label} for variables. Variables with the same id are connected.
     // Example:
     "Print to console": {
        "prefix": "log",
        "body": [
            "console.log("$1");",
            "$2"
        ],
        "description": "Log output to console"
    }
*/
 "Simple Console Program With Data Input And Output": {
        "prefix": "simple",
        "body": [""""Simple Console Program With Data Input And Output."""
import sys

def read_int():
    """Read a seris of numbers."""
    return list(map(int, sys.stdin.readline().split()))


def read_float():
    """Read a seris of float numbers."""
    return list(map(float, sys.stdin.readline().split()))


def read_word():
    """Read a seris of string."""
    return list(map(str, sys.stdin.readline().split()))


def combine_with(seq, sep=" ", num=None):
    """Combine list enum with a character and return the string object"""
    res = sep.join(list(map(str, seq)))
    if num is not None:
        res = str(seq[0])
        for element in range(1, len(seq)):
            res += sep + str(seq[element]) if element % num != 0 else "
" + str(seq[element])
    return res


def main():
    """The main function."""
    pass


if __name__ == "__main__":
    sys.exit(int(main() or 0))
"
        ],
        "description": "Simple Console Program With Data Input And Output"
    }
}```
 然后再編寫Python代碼的時候，鍵入"simple"就可以自動輸入以上模板。
