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:
inBoolean (True/False)Case-sensitiveNo errorsQuick check for substring presence find()Integer (index or -1)Case-sensitiveReturns-1if not foundFinding position without exceptions index()Integer (index)Case-sensitiveRaises ValueError if not foundEnsuring substring is present re.search()Match object or ...
规则3: 比较两个字符串或两个数字类型, 比较结果是符合预期的(字符串是字典顺序, 整型是数字大小的顺序) 原文: When you order two strings or two numeric types the ordering is done in the expected way (lexicographic ordering for string, numeric ordering for integers). 规则4:比较数字类型和非数字类型...
Enum string comparison To compare a string with an enum, extend from thestrclass when declaring your enumeration class, e.g.class Color(str, Enum):. You will then be able to compare a string to an enum member using the equality operator==. How to compare a string with an Enum in Pyt...

The uppercase "A" has a lower Unicode point than the lowercase "a". So, "A" is less than "a". In the end, Python compares characters using integer numbers. So, the same rules that Python uses to compare integers apply to string comparison. When it comes to strings with several chara...

They are case-sensitive: thing, Thing, and THING are different names. They must begin with a letter or an underscore, not a digit. Names that begin with an underscore are treated specially (which you can read about in Chapter 9). They cannot be one of Python’s reserved words (also kn...
Seeimplicit string concatenationfor more on this feature. Boolean Python's two Boolean values areTrueandFalse. These values both have thetypeofbool, which stands for Boolean (named afterGeorge Boole, in case you're curious). These values are used for representing a binary state (meaning there ...
