在需要进行字符串拼接时建议使用 str类型的join方法,而非+ ,因为join()方法是先计算出所有字符中的长度,然后再拷贝,只new一次对象,效率要比"+"效率高 。 二、字符串类型的操作 Python类str内置源码: class str(object): """ str = "(对象)——> str ...
字符串:str(注:\t等于一个tab键) 布尔值: bool 列表:list 列表用[] 元祖:tuple 元祖用() 字典:dict 注:所有的数据类型都存在想对应的类列里 二.字符串所有数据类型: 基本操作: 索引,切片,追加,删除,长度,切片,循环,包含 classstr(object):
str.split(" ") # Iterate through each word 'x' in the list of words 'txt' for x in txt: # Check if the length of the current word 'x' is greater than 'n' if len(x) > n: # If the word is longer than 'n' characters, add it to the 'word_len' list word_len.append(x...
