根据函数名生成代码

import time

def getUnixTimeStamp():
    return int(time.time())

生成测试用例

import os


def get_file_content(filename):
    if not os.path.exists(filename):
        raise Exception("File does not exist: " + filename)
    with open(filename) as f:
        return f.read()


if __name__ == '__main__':
    # test get_file_content
    print(get_file_content("test.py"))

使用 JSON 生成类

# create User class from json {"code": 200, "username":"test", "email":"123@asd.com", "date":"2022-04-17"}
class User:
    def __init__(self, code, username, email, date):
        self.code = code
        self.username = username
        self.email = email
        self.date = date

    def __repr__(self):
        return f"User(code={self.code}, username={self.username}, email={self.email}, date={self.date})"

    def __eq__(self, other):
        return self.code == other.code and self.username == other.username and self.email == other.email and self.date == other.date

    def __hash__(self):
        return hash((self.code, self.username, self.email, self.date))

    def to_dict(self):
        return {"code": self.code, "username": self.username, "email": self.email, "date": self.date}

    @staticmethod
    def from_dict(obj):
        assert isinstance(obj, dict)
        code = obj.get("code")
        username = obj.get("username")
        email = obj.get("email")
        date = obj.get("date")
        return User(code, username, email, date)

    def to_json(self):
        return json.dumps(self.to_dict(), indent=2)

    @staticmethod
    def from_json(json_str):
        return User.from_dict(json.loads(json_str))

使用建表语句生成代码

# create User class from sql
# CREATE TABLE User( `id` INT UNSIGNED AUTO_INCREMENT KEY,`username` VARCHAR(20) NOT NULL UNIQUE, `password` CHAR(32) NOT NULL,`email` VARCHAR(50) NOT NULL) CHARSET=UTF8;
class User:
    def __init__(self, id, username, password, email):
        self.id = id
        self.username = username
        self.password = password
        self.email = email

    def __repr__(self):
        return '<User %r>' % self.username
