What if you're trying to do a case-insensitive comparison between strings? You could lowercase or uppercase all of your strings for the comparison. Or you could use the string casefold method: >>> name = "Trey" >>> "t" in name False >>> "t" in name.casefold() True But wait,...
Strings in Python are case-sensitive, which means thatMoonandmoonare considered different words. To do a case-insensitive comparison, you can convert a string to all lowercase letters by using the.lower()method: Python print("The Moon And The Earth".lower()) ...
endswith - ends with string value iendswith - ends with string value, case insensitive regex - matches a regex expression iregex - matches a regex expression, case insensitive 查看具有关系 利用has方法查看节点是否有一种或多种方法,True 为有,False为无 ...
该函数是大小写敏感的,如果想大小写不敏感,那么可以使用 positionCaseInsensitive。还有一点需要注意,该函数是按照字节统计的。 position('古明地觉A', 'A') 得到的是 13,因为一个汉字 3 字节 如果包含中文,想按照字符统计,则需要使用 positionUTF8。
此模块支持模式匹配、搜索和字符串操作。re.search()、re.match()和re.sub()等内置函数允许进行复杂的模式匹配。如果没有re模块,Python 支持使用.find()、.startswith()、.endswith()和.replace()等方法进行基本模式匹配。虽然这些内置方法允许基本匹配,但re模块对于更高级的正则表达式操作是必需的。

The color name string you pass to ImageColor.getcolor() is case insensitive, so passing 'red' ❷ and passing 'RED' ❸ give you the same RGBA tuple. You can also pass more unusual color names, like 'chocolate' and 'Cornflower Blue'. Pillow supports a huge number of color names, ...
