用于解答算法题目的Python3代码框架，,前言最近在实习，任务

前言

最近在实习，任务并不是很重，就利用闲暇时间使用Python3在PAT网站上刷题，并致力于使用Python3的特性和函数式编程的理念，其中大部分题目都有着类似的输入输出格式，例如一行读入若干个数字，字符串，每行输出多少个字符串等等，所以产生了很多重复的代码。

Python代码

于是我就利用VS Code的代码片段功能编写了一个用于处理这些输入输出的代码框架，并加入了测试功能（写函数前先写测试时正确的事情）。代码如下

"""Simple Console Program With Data Input And Output."""import sysimport iodefread_int():    """Read a seris of numbers."""    return list(map(int, sys.stdin.readline().split()))deftest_read_int():    """Test the read_int function"""    test_file = io.StringIO("1 2 3\n")    sys.stdin = test_file    assert read_int() == [1, 2, 3], "read_int error"defread_float():    """Read a seris of float numbers."""    return list(map(float, sys.stdin.readline().split()))deftest_read_float():    """Test the read_float function"""    test_file = io.StringIO("1 2 3\n")    sys.stdin = test_file    assert read_float() == [1.0, 2.0, 3.0], "read_float error"defread_word():    """Read a seris of string."""    return list(map(str, sys.stdin.readline().split()))deftest_read_word():    """Test the read_word function"""    test_file = io.StringIO("1 2 3\n")    sys.stdin = test_file    assert read_word() == ["1", "2", "3"], "read_word error"defcombine_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 ‘\n‘ +                 str(seq[element])    return resdeftest_combile_with():    """Test the combile_with function."""    assert combine_with([1, 2, 3, 4, 5], ‘*‘, 2) == """1*2 3*4 5""", "combine_with error."defmain():    """The main function."""    passif __name__ == ‘__main__‘:    sys.exit(int(main() or 0))

VS Code代码片段

添加到VS Code的默认代码片段的操作大致如下：

{/*   // 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.\"\"\"\nimport sys\n\ndef read_int():\n \"\"\"Read a seris of numbers.\"\"\"\n return list(map(int, sys.stdin.readline().split()))\n\n\ndef read_float():\n \"\"\"Read a seris of float numbers.\"\"\"\n return list(map(float, sys.stdin.readline().split()))\n\n\ndef read_word():\n \"\"\"Read a seris of string.\"\"\"\n return list(map(str, sys.stdin.readline().split()))\n\n\ndef combine_with(seq, sep=‘ ‘, num=None):\n \"\"\"Combine list enum with a character and return the string object\"\"\"\n res = sep.join(list(map(str, seq)))\n if num is not None:\n res = str(seq[0])\n for element in range(1, len(seq)):\n res += sep + str(seq[element]) if element % num != 0 else ‘\\n‘ + str(seq[element])\n return res\n\n\ndef main():\n \"\"\"The main function.\"\"\"\n pass\n\n\nif __name__ == ‘__main__‘:\n sys.exit(int(main() or 0))\n"      ],      "description": "Simple Console Program With Data Input And Output"  }}
