Write a Python program to take user input and display the text in both uppercase and lowercase formats. Write a Python program to accept a sentence and print it in all capital letters on one line and all small letters on another. Write a Python program to convert the input string into up...
string.upper(), string.lower() and string.title() Methods are inbuilt methods inPython, these are used to format string in a particular format like uppercases, lowercase or little case format. string.upper(),string.lower()和string.title()方法是Python中的内置方法,用于将字符串格式化为特殊格式...
In this short tutorial, we are going to look into what Python lowercase methods are. We will also consider some examples to clearly understand the concepts. An Introduction to Python lowercase While working with strings, there might be instances where we need to convert uppercase strings to lowe...
Return a copy of the string S converted to lowercase. >>>str3="HELLO WORLD">>>str3.lower()'hello world' upper S.upper() -> str #把字符串里所有的字符都转换为大写字母 Return a copy of S converted to uppercase. >>>str1="hello world">>>str1.upper()'HELLO WORLD' ...
以一致的规则为你的类和函数命名;按照惯例应使用 UpperCamelCase 来命名类,而以 lowercase_with_underscores 来命名函数和方法。 始终应使用 self 来命名第一个方法参数 (有关类和方法的更多信息请参阅 初探类)。 如果你的代码旨在用于国际环境,请不要使用花哨的编码。Python 默认的 UTF-8 或者纯 ASCII 在任何...
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...
-b(单个小写字母) -B(单个大写字母) -lowercase(单个小写单词) -lower_case_with_underscores(多个单词,下划线表示) -UPPERCASE(单个大写单词) -UPPER_CASE_WITH_UNDERSCORES(单个大写单词下划线表示) -CapitalizedWords(驼峰命名,通常用于类名) - 在CapWords中使用首字母缩写时,首字母缩写的所有字母都要大写。因此,...
