您可以在autbor.com/convertlowercase查看该程序的执行情况。如果字符串至少有一个字母并且所有字母都是大写或小写,那么isupper()和islower()方法将返回一个布尔值True。否则,该方法返回False。在交互式 Shell 中输入以下内容,并注意每个方法调用返回的内容:
uppercase; else, it will return the same original string itself. To do the opposite of this method, an upper() function does exactly the opposite of the lower() function; it returns the capital letters from the given string, which is in lowercase and converts it into upper. The lower(...

lowercased: hello python!uppercased: HELLOPYTHON!字符串数据处理 2.DRY（不要重复自己）DRY（不要重复自己）的原理是每个程序员都应该实践的最基本的规则之一。其含义很简单：如果发现代码中有任何重复，那么就表明需要进行一些重构，以实现最大程度地减少重复代码，或在可能的情况下完全删除任何重复信号。以下示例...
uppercase_string = combined_string.upper() # 结果为 'HELLO, WORLD!' lowercase_string = combined_string.lower() # 结果为 'hello, world!' (8)字符串替换 使用replace()方法可以替换字符串中的子串。 replaced_string = combined_string.replace('World', 'Python') # 结果为 'Hello, Python!' ...
