Python has a set of built-in methods that you can use on strings.Note: All string methods return new values. They do not change the original string.MethodDescription capitalize() Converts the first character to upper case casefold() Converts string into lower case center() Returns a ...
The .upper() and .lower() string methods are self-explanatory. Performing the .upper() method on a string converts all of the characters to uppercase, whereas the lower() method converts all of the characters to lowercase.>>> s =“Whereof one cannot speak, thereof one must be silent....
1. str.capitalize() View Code 2. center(width[, fillchar]) View Code 3. count(sub, start= 0,end=len(string) View Code 4. decode(encoding='UTF-8',errors='strict') encode(encoding='base64',errors='strict') View Code 5. endswith(suffix[, start[, end]]) View Code 6. expandtabs...
str.index(sub[, start[, end]]) --> int检测字符串string中是否包含子字符串,如果存在,则返回sub在string中的索引值(下标),如果指定began(开始)和end(结束)范围,则检查是否包含在指定范围内,该方法与python find()方法一样,只不过如果str不在string中会报一个异常(ValueError: substring not found)。 >>>...
Python's strings have dozens of methods, but some are much more useful than others. Let's discuss the dozen-ish must-know string methods and why the other methods aren't so essential.
Sometimes a Python string method returns true if the string matches a specific case. Otherwise, it returns false. Other Python string methods are just used to format text — it returns a string that’s been properly formatted. From machine learning to GUIs, string methods are important to ensu...
官网文档地址:https://docs.python.org/3/library/stdtypes.html#string-methods 官网文档里的所有String的方法都在下面,基于Python3.X 版本。花了一天的时间学习并记录了一下String方法的详细内容。 4.7.1. String Methods str.capitalize() --> String 返回字符串,其首字母大写,其余部分小写 ...
Python String Methods 3 Python ljust()方法 --rjust())#返回一个原字符串左对齐,并使用空格填充至指定长度的新字符串。如果指定的长度小于原字符串的长度则返回原字符串 View Code Python lower()方法 --Python upper() #转换字符串中所有大写字符为小写...
In this unit, you use the most common string methods in Python to manipulate strings, from simple transformations to more advanced search-and-replace operations.
There are a bunch of fun methods for transforming our string text. Among those that are more important to understand to make real-world applications we can find thelower(),upper(), strip(), count()andjoin()methods. Thestrip()method is useful when dealing with user input as it gets rid...
