在编程中,控制结构用于决定程序的执行流程。Python 提供了丰富的控制结构,如条件语句(if-else)、循环语句(for 和 while)等。条件语句允许我们根据不同的条件执行不同的代码块。例如: 循环语句则用于重复执行一段代码。for 循环常用于遍历一个序列,如: while 循环则在条件为真时一直执行,如: 三、Python 函数与模...
1.strip(): Return a copy of the string s with leading and trailing whitespace removed. >>> test_str = ' I Love Python ' >>> string.strip(test_str) 'I Love Pyhon' Note that : whitespace at the two side of the string were removed ,but it did not worked on the whitespace between...
The lambda function calls .strip() on the string object s and removes all the leading and trailing dots.This technique can be handy when, for example, you’re processing text files in which lines can have trailing spaces (or other characters) and you need to remove them. If this is the...

25、rstrip() string method to strip trailing whitespace from each line. (Strings also have an lstrip() method to strip leading whitespace, and a strip() method which strips both.) 26、zip()、tuple()、dict()、translate()、eval() characters = ('S', 'M', 'E', 'D', 'O', 'N',...
