print( "Strip unwanted characters: {}" .format(s.rstrip( "A" ))) 1. 2. 必要时不要忘记检查字符串 format()文档。 2.字符串拆分 利用Python中的 split() 方法可以轻易将字符串拆分成较小的子字符串列表 split() 方法:https://docs.python.org/3/library/stdtypes.html#str.split s = "KDnuggets...
1、调用方法split和rsplit劈分字符串,split从字符串左侧劈分,rsplit从右侧劈分。 默认的劈分符是空格字符串,这两种方法的返回值都是一个列表。 代码语言:javascript 复制 s='Python Swift Kotlin'print(s.split())#['Python','Swift','Kotlin']print(s.rsplit())#['Python','Swift','Kotlin']# 可以通...

Thestr.splitmethod returns a list of the words in the string, separated by the delimiter string. The parameters are: sep − Optional. Character dividing the string into split groups; default is space. maxsplit − Optional. Number of splits to do; default is -1 which splits all the ...
str.rindex(sub[, start[, end]]) --> String 返回子字符串str 在字符串中最后出现的位置,如果没有匹配的字符串会报异常,你可以指定可选参数[beg:end]设置查找的区间。 str.split(sep=None, maxsplit=-1) --> list 通过指定分隔符对字符串进行切片,如果参数num有指定值,则仅分隔num 个子字符串str.r...
我们可以使用Python内置的字符串函数split()将字符串拆分成单个字符。然后,使用Python的字典数据结构来记录每个字符出现的次数。最后,使用第三方库matplotlib中的pyplot模块绘制饼状图。 下面是具体的实现代码: 代码解读 importmatplotlib.pyplotaspltdefcount_characters(text):characters={}# 用于记录字符出现次数的字典# ...
