多列代码块进行技术配置对比: # 方案A: 使用内置字符串方法defcompare_case_sensitive(str1,str2):returnstr1==str2# 方案B: 使用内置方法忽略大小写defcompare_case_insensitive(str1,str2):returnstr1.lower()==str2.lower() 1. 2. 3. 4. 5. 6. 7.
下面是一个示例代码: defcompare_case_insensitive(str1,str2):returnstr1.lower()==str2.lower()# 示例print(compare_case_insensitive("Hello","hello"))# 输出: Trueprint(compare_case_insensitive("Python","PYTHON"))# 输出: Trueprint(compare_case_insensitive("Test","Test123"))# 输出: False 1...

The message field matches the start of the warning mes- sage printed; this match is case-insensitive. The SunOS 5.11 Last change: $Date$ 3 User Commands PYTHON(1) category field matches the warning category. This must be a class name; the match test whether the actual warning category of...
str.casefold() is the way to go for case-insensitive comparisons. If you work with text in many languages, a pair of functions like nfc_equal and fold_equal in Example 4-13 are useful additions to your toolbox. Example 4-13. normeq.py: normalized Unicode string comparison """ Utility...
Note that while lookup() and \N{} are case-insensitive, name() always returns the character’s name in uppercase. Lastly, a pretty common use case for escape sequences that you might encounter in Python is ANSI escape codes, which control the formatting and display of text in your ...
