txt简易恶搞小代码

下面是一个简易的恶搞小代码示例：

import random

txt = "这是一段普通的文本。"

def evil_joke(txt):
    new_txt = ""
    for char in txt:
        if random.random() < 0.1:
            new_char = char.upper()
        else:
            new_char = char.lower()
        new_txt += new_char
    return new_txt

evil_txt = evil_joke(txt)
print(evil_txt)

这段代码会将输入的文本中的每个字符以一定的概率转换为大写或小写字母，从而实现简单的恶搞效果。你可以根据自己的需要调整概率值，使恶搞效果更或者更少。

android 简易记事本 源代码

以下是一个简单的 Android 记事本应用的源代码，你可以参考一下：

MainActivity.java：

import android.os.Bundle;
import android.view.View;
import android.widget.EditText;

Python银行管理系统简易代码

以下是一个Python版简易银行管理系统的代码示例，实现了开户、账户查询、存取款、转账、改密、锁定、解锁、补卡、销户等银行管理操作。账户信息存在allusers.txt中，通过该文件的读存来实现账户的管理。
