file-- 要写入的文件对象。 file 参数必须是一个具有write(string)方法的对象;如果参数不存在或为None,则将使用sys.stdout。 由于要打印的参数会被转换为文本字符串,因此print()不能用于二进制模式的文件对象。 对于这些对象,可以使用file.write(...)。 🐹 2. 数据的格式化输出 在C语言中,我们可以使用printf(...

Find all indexes of substring There is no built-in function to get the list of all the indexes for the substring. However, we can easily define one using find() function. def find_all_indexes(input_str, substring): l2 = [] length = len(input_str) ...

str.find(substring) 如果子字符串存在于字符串中,则返回最低索引;否则它返回 -1。str.rfind(substring) 返回最高索引。如果找到,str.index(substring) 和str.rindex(substring) 也分别返回子字符串的最低和最高索引。如果字符串中不存在子字符串,则会引发 ValueError 代码语言:javascript 代码运行次数:0 运行 AI...
事实上,这就是我们在代码开头使用行import string的原因——这样我们就可以与字符串对象交互。第二,一旦链接是一个字符串,你可以看到我们如何使用 Python 的in调用。类似于 C#的String.contains()方法,Python 的in调用只是搜索字符串,看它是否包含请求的子串。在我们的案例中如果我们要找的是。pdf 文件,我们可以在...
