1. Use the Simplest Python Return Tuple You can use a tuple as the return value from a function in Python by simply enclosing the values you want to return inparentheses– (), separated by commas. Returning a tuple from a function enables us to return multiple types of values from a fun...
max()andmin()function To find the maximum value in a tuple, we can use themax()function, while for finding the minimum value,min()function can be used. >>> t = (1, 4, 2, 7, 3, 9) >>> print (max(t)) >>> print (min(t)) ...

在删除列表元素时,Python会自动对列表内存进行收缩并移动列表元素以保证所有元素之间没有空隙,增加列表元素时也会自动扩展内存并对元素进行移动以保证元素之间没有空隙。每当插入或删除一个元素之后,该元素位置后面所有元素的索引就都改变了。 x = [1,2,1,2,1,1,1] for item in x: if item == 1: x.remov...
To return a tuple in your Python function, simply create your tuple object and return it in your function as you would return any other value, or simply list all components of your tuple in the return statement.
L.remove(value) -- remove first occurrence of value. insert() 在某个场索引前插入一个元素 L.insert(index, object) -- insert object before index sort() 给列表陫序 L.sort(cmp=None, key=None, reverse=False) -- stable sortIN PLACE; ...
