这绝对是一个对你帮助很大的文章。这篇文章将手把手教你用Python编写一个操作系统，最震撼的当属它不用第三方库
1.创建窗口
这步将让你可以在一个窗口上显示操作系统，让他不会成为MS-DOS那样的文字系统
import tkinter as tk
import time
2.备忘录功能
可以让你拥有一个属于自己的备忘录（记得每次编辑完后按保存）
class TextEditor:
def __init__(self,root):
self.root = root
self.T = tk.Text(root, height=10, width=50)
self.T.pack()
self.save_button = tk.Button(root, text="保存", command=self.save_text)
self.save_button.pack()
self.load_button = tk.Button(root, text="读取", command=self.load_text)
self.load_button.pack()
def save_text(self):
with open("saved.txt", "w") as f:
f.write(self.T.get("1.0", "end"))
def load_text(self):
with open("saved.txt", "r") as f:
self.T.delete("1.0", "end")
self.T.insert("1.0", f.read())
3.计算器功能
我这里只弄了加法和减法，想要其它运算可以自己开发
class Calculator:
def __init__(self,root):
self.root = root
self.result_label = tk.Label(root, text="结果: ")
self.result_label.pack()
self.num1_entry = tk.Entry(root)
self.num1_entry.pack()
self.num2_entry = tk.Entry(root)
self.num2_entry.pack()
self.add_button = tk.Button(root, text="加", command=self.add_nums)
self.add_button.pack()
self.subtract_button = tk.Button(root, text="减", command=self.subtract_nums)
self.subtract_button.pack()
def add_nums(self):
num1 = float(self.num1_entry.get())
num2 = float(self.num2_entry.get())
result = num1 + num2
self.result_label.config(text="结果: " + str(result))
def subtract_nums(self):
num1 = float(self.num1_entry.get())
num2 = float(self.num2_entry.get())
result = num1 - num2
self.result_label.config(text="结果: " + str(result))
class Clock:
def __init__(self,root):
self.root = root
self.time_label = tk.Label(root, text="")
self.time_label.pack()
self.update_clock()
def update_clock(self):
current_time = time.strftime("%H:%M:%S")
self.time_label.config(text=current_time)
self.time_label.after(1000, self.update_clock)
4.存储器功能
类似于游戏中的一个存档码对应一个存档，一个代码对应一个信息
SaveInfo:
def __init__(self,root):
self.root = root
self.info_label = tk.Label(root, text="输入信息:")
self.info_label.pack()
self.info_entry = tk.Entry(root)
self.info_entry.pack()
self.code_label = tk.Label(root, text="输入代码:")
self.code_label.pack()
self.code_entry = tk.Entry(root)
self.code_entry.pack()
self.save_button = tk.Button(root, text="保存", command=self.save_info)
self.save_button.pack()
self.load_button = tk.Button(root, text="读取", command=self.load_info)
self.load_button.pack()
def save_info(self):
info = self.info_entry.get()
code = self.code_entry.get()
with open(f"{code}.txt", "w") as f:
f.write(info)
self.info_entry.delete(0, "end")
self.code_entry.delete(0, "end")
def load_info(self):
code = self.code_entry.get()
try:
with open(f"{code}.txt", "r") as f:
info = f.read()
self.info_entry.delete(0, "end")
self.info_entry.insert(0, info)
except FileNotFoundError:
self.info_entry.delete(0, "end")
self.info_entry.insert(0, "未找到代码")
5.命名窗口
命名你的窗口，可以自己修改
if __name__ == "__main__":
root = tk.Tk()
root.title("新文本系统")
text_editor = TextEditor(root)
calculator = Calculator(root)
clock = Clock(root)
save_info = SaveInfo(root)
root.mainloop()
由此可知，代码是
import tkinter as tk
import time
class TextEditor:
def __init__(self,root):
self.root = root
self.T = tk.Text(root, height=10, width=50)
self.T.pack()
self.save_button = tk.Button(root, text="保存", command=self.save_text)
self.save_button.pack()
self.load_button = tk.Button(root, text="读取", command=self.load_text)
self.load_button.pack()
def save_text(self):
with open("saved.txt", "w") as f:
f.write(self.T.get("1.0", "end"))
def load_text(self):
with open("saved.txt", "r") as f:
self.T.delete("1.0", "end")
self.T.insert("1.0", f.read())
class Calculator:
def __init__(self,root):
self.root = root
self.result_label = tk.Label(root, text="结果: ")
self.result_label.pack()
self.num1_entry = tk.Entry(root)
self.num1_entry.pack()
self.num2_entry = tk.Entry(root)
self.num2_entry.pack()
self.add_button = tk.Button(root, text="加", command=self.add_nums)
self.add_button.pack()
self.subtract_button = tk.Button(root, text="减", command=self.subtract_nums)
self.subtract_button.pack()
def add_nums(self):
num1 = float(self.num1_entry.get())
num2 = float(self.num2_entry.get())
result = num1 + num2
self.result_label.config(text="结果: " + str(result))
def subtract_nums(self):
num1 = float(self.num1_entry.get())
num2 = float(self.num2_entry.get())
result = num1 - num2
self.result_label.config(text="结果: " + str(result))
class Clock:
def __init__(self,root):
self.root = root
self.time_label = tk.Label(root, text="")
self.time_label.pack()
self.update_clock()
def update_clock(self):
current_time = time.strftime("%H:%M:%S")
self.time_label.config(text=current_time)
self.time_label.after(1000, self.update_clock)
class SaveInfo:
def __init__(self,root):
self.root = root
self.info_label = tk.Label(root, text="输入信息:")
self.info_label.pack()
self.info_entry = tk.Entry(root)
self.info_entry.pack()
self.code_label = tk.Label(root, text="输入代码:")
self.code_label.pack()
self.code_entry = tk.Entry(root)
self.code_entry.pack()
self.save_button = tk.Button(root, text="保存", command=self.save_info)
self.save_button.pack()
self.load_button = tk.Button(root, text="读取", command=self.load_info)
self.load_button.pack()
def save_info(self):
info = self.info_entry.get()
code = self.code_entry.get()
with open(f"{code}.txt", "w") as f:
f.write(info)
self.info_entry.delete(0, "end")
self.code_entry.delete(0, "end")
def load_info(self):
code = self.code_entry.get()
try:
with open(f"{code}.txt", "r") as f:
info = f.read()
self.info_entry.delete(0, "end")
self.info_entry.insert(0, info)
except FileNotFoundError:
self.info_entry.delete(0, "end")
self.info_entry.insert(0, "未找到代码")
if __name__ == "__main__":
root = tk.Tk()
root.title("新文本系统")
text_editor = TextEditor(root)
calculator = Calculator(root)
clock = Clock(root)
save_info = SaveInfo(root)
root.mainloop()
记得把这个程序放到单独一个文件夹中
