去两边字符串:str.strip('d'),相应的也有lstrip,rstrip str=' python String function ' print '%s strip=%s' % (str,str.strip()) str='python String function' print '%s strip=%s' % (str,str.strip('d')) 按指定字符分割字符串为数组:str.
生成字符串变量str='python String function' 字符串长度获取:len(str) 例:print '%s length=%d' % (str,len(str)) 1.字母处理 全部大写:str.upper() 全部小写:str.lower() 大小写互换:str.swapcase() 首字母大写,其余小写:str.capitalize() 首字母大写:str.title() print '%s lower=%s' % (str,str...
which results in the continuous repetition of the string as many times as the number indicates. Also, if we want to find out thelengthof the string, we simply have to use thelen() function as shown in the example below:
Python提供了以下几个拆分字符串的函数,主要将字符串拆分成多个子串。 注意示例中存在string和string1两个字符串,函数 partition 和 rpartition 将字符串拆分为3部分,这两个函数总是返回一个这样的值:由3个字符串组成, 形式为 (head, sep, tail) ;而函数 split 以指定字符串为分隔符,将 字符串划分为一系列子...
A. len() B. length() C. strlen() D. stringLength() 相关知识点: 试题来源: 解析 A。在 Python 中,获取字符串长度的函数是 len()。length()、strlen()、stringLength()在 Python 中都不是获取字符串长度的函数。反馈 收藏

The len() function in Python returns the number of items in an object, such as strings, lists, or dictionaries. To get the length of a string in Python, you use len() with the string as an argument, like len("example"). To find the length of a list in Python, you pass the ...
