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()) ...
This membership test returns False because strings comparisons are case-sensitive, and "PYTHON" in uppercase isn’t present in greeting. To work around this case sensitivity, you can normalize all your strings using either the .upper() or .lower() method:...
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....
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...

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...
